The dial on the latest elegant Grand Seiko Spring Drive watch beautifully mimics the undulations of lake Suwa when its surface is frozen, a natural phenomenon called Omiwatari.
Grand Seiko says its watchmakers and dial designers were inspired by the lake to create the ice-blue dial on the new SBGY007, a 38.5mm steel watch.
To make the dial, Grand Seiko artisans at the Shinshu Watch Studio near Lake Suwa hammered the dial’s mold to create the visible edges and the round shape, then polished the indexes and sharpened the hands.
Thanks to these angles and colors, light glimmers across the hands and dial, a result said to reflect Grand Seiko’s Nature of Time design philosophy.
Grand Seiko powers the watch with its own hybrid, super-precise Spring Drive Caliber 9R31, with dual barrels that deliver a power reserve of 72 hours when fully wound. Turning the watch over, viewers can eye the nicely finished Spring Drive movement, beautifully flecked with tempered blue screws and its power reserve indicator.
Grand Seiko expects this new SBGY007 to be made available in early July at Grand Seiko Boutiques and retail partners. Price: $8,300.
Specifications: Grand Seiko Elegance Collection SBGY007
Movement: Manual-winding Spring Drive Caliber 9R31. Driving system: Spring Drive with accuracy: ±1 second per day / ±15 seconds per month (average) power reserve: 72 Hours.
Dial: Hand-hammered ice blue, polished and faceted hands and markers.
Case: 38.5mm by 10.2mm steel, water resistant to 30 meters.
De Bethune’s new diver, introduced late last year and affectionately called the Yellow Submarine, brings a whole new look to the dive genre. While the DB28GSVY embraces the warmer tones of gold, amber and orange, its case and components are not crafted in gold but are actually made from heat-treated titanium and steel.
Mounted on De Bethune’s articulated case/lug platform, the Yellow Submarine embodies the past and future of watchmaking in a single case. Space-age design and materials are married to traditional watchmaking solutions and then taken to the next level.
Powering the watch is the DeBethune manual-wind caliber DB2080, which is comprised of 400 individual components, including 51 jewels. Power reserve is stretched to five days thanks to a dual-barrel system as well as the fine-tuned escapement, with its titanium balance, white gold inserts and a profile designed to minimize fluid friction. The balance wheel cycles at 28,800 beats per hour.
Releasing power to the unique balance is an escape wheel crafted in silicon. The entire escapement assembly is protected by a triple Pare-Chute system developed in-house by De Bethune. Other unique aspects to this particular timepiece include that it eschews the normal practice of slathering luminous paint everywhere to read the time. Only the hands have slim strips of lume while an amazing electro-mechanical system creates light via a micro-dynamo and LED lighting system activated by the push of the actuator at 6 o’clock.
Push the button and watch the repeater-like regulator spin while four LED sources cast light across the dial. Since this is technically a dive watch it also incorporates a rotating bezel, but in this case the outer coin-edge grip actually rotates an inner rehaute with pierced cutouts showing beautiful blue numerals. The 44mm case mounts the crown at 12 o’clock. Each example of the twenty-five in this very limited edition is priced at $110,000.
MB&F has expanded and updated its popular Legacy Machine 101 collection, which features one of the independent watchmaker’s most compact (40mm) creations and the first to be powered by a movement entirely designed and built by the watchmaker’s own engineering team.
A dramatic suspended balance wheel still dominates the LM101, but this latest design enhances the dial display with a double hairspring. You might recognize the addition: It’s the same hairspring found in the LM101 MB&F x H. Moser collaboration, which sold out quickly after its debut last year.
Reading the time and the power reserve on the new LM101 is also made easier thanks to larger subdials and a slimmer bezel than we’ve seen on previous versions of the watch. Underneath the new hairspring and larger subdials MB&F is offering a new dial for this latest LM101.
In addition to the three new lacquered dial colors, note the new finely engraved sunray pattern, which MB&F places directly on top of the movement plate.
And finally, one of the three LM101 debuts is cased in steel, which MB&F utilizes fairly infrequently as a case material. The debut includes three editions: white gold with a striking purple dial, red gold with a handsome dark blue dial ($68,000) and in a stainless steel case with a light blue dial ($56,000).
Specifications: MB&F Legacy Machine 101
Movement: Three-dimensional horological movement developed in-house by MB&F. Aesthetics and finishing specifications by Kari Voutilainen. Manual winding with single mainspring barrel and power reserve of 45 hours. The balance is 14mm balance wheel with four traditional regulating screws floating above the movement. The balance spring, via H. Moser, features a traditional Breguet curve terminating in mobile stud holder and a Straumann double hairspring. Balance frequency is 18,000bph (2.5Hz). Finishing includes gold chatons with polished countersinks, fine hand finishing with superlative 19th century-style; internal bevel angles, polished bevels, Geneva waves; hand-made engravings, NAC black bridges for the 2021 editions.
Dial: Lacquered royal blue, light blue or purple. Hours, minutes and power reserve indicator and large 14mm suspended balance wheel.
Case: 40mm x16mm in white gold, red gold and stainless steel. High domed crystal sapphire on top and box sapphire crystal on back, both with anti-reflective coating on both sides.
Strap: Hand-stitched alligator or veal strap with buckle to match the case.
Junghans celebrates its 160th anniversary this year with an impressive array of new watches that primarily feature the German-based watchmaker and clockmaker’s historically based Max Bill and Meister collections.
In addition, Junghans adds a limited-edition model to its newer, minimalist Form line while also reviving a long-time favorite kitchen clock/timer it originally debuted in the 1950s.
Here, we’ll focus on the additions to the Meister line, with special attention to the Meister Signature Hand-winding Edition 160. Look to future postings for details about the clock and the Max Bill collection updates, or check them out here on the Junghans website.
The new Meister Signature Hand-winding Edition 160 is a manual-wind model cased in 18-karat gold and fit with an interesting Junghans movement that oscillates at a leisurely 18,000 bph. Measuring a wrist-friendly 39mm in diameter, the limited edition (of 160) watch recalls dress watch styling from the 1960s and 1970s, which Junghans underscores with a decidedly retro rendition of its brand name, as seen on Junghans products of yore.
Junghans produced the original J620 hand-winding movement between 1966 and 1975 and utilized it for a wide range of mechanical three-hand wristwatches. The J620 can also be found in the Junghans Olympic series of 14-karat gold watches made in 1971 and 1972.
For the new watch, Junghans has disassembled, decorated and reassembled existing, historical J620 movements, plating each with a coat of 18-karat rose gold for good measure. And Junghans has thoughtfully provided a clear sapphire caseback to view the work. Price: $9,800.
Meister Power Reserve
Displaying an unusual vertical power reserve indicator just above the 6 o’clock position, the new Meister Gangreserve (power reserve) Edition 160 echoes a similar design Junghans released in the 1950s.
As the power reserve recedes, the indicator’s color on the steel-bracelet model gradually changes from green to yellow and finally to red, which indicates that it’s time to wind the automatic watch again. Two leather-strap models are more subtle: When fully charged, the indicator shows the dial color (see example below). At fifty percent power, the indicator turn gray, and when power drops to zero, the indicator shows red. The Meister Gangreserve Edition 160 is limited to only 160 watches in each of three versions. Prices start at $1,700.
Meister Fein Automatic
This very modern design features a new convex case to frame its minimalist dial. Though not technically thin, it appears so on the wrist with a 39.5mm diameter, almost absent bezel and long hands and markers.
Only a date window interrupts the finely detailed dial. Inside, Junghans places a self-winding (ETA-based) J800.1 movement with a power reserve of up to 38 hours. Prices begin at $1,450.
Meister S Chronoscope, Platinum Edition 160
Junghans cases its most limited anniversary model in polished platinum. The Chronoscope is one of the brand’s top sellers, and here Junghans creates a twelve-piece numbered edition, with the limited edition number cleverly noted within the twelve-hour counter.
The 45mm by 15.9mm watch features a screwed solid platinum case back with edition logo engraving and a platinum screwed crown (and tube). Its dial reflects the precious case with a gold-hued markers and a nice lacquer finish that fades from matte silver-plate in the center to grey at the edge, set with luminous markers.
The synthetic rubber strap features an alligator leather inlay and a platinum buckle. Price: $19,200.
Movement: Historical hand-winding Junghans movement J620 with a power reserve of up to 45 hours, 18,000 bph, rose-gold plated, sunburst ratchet wheel, polished barrel bridge, gear bridge and balance cock with fine longitudinal grinding, stones in polished, bowl-shaped countersinks, outside with fine diamond cut, polished steel screws, Junghans star and caliber number engraving.
Case: 39mm by 10.3mm rose gold, five-times screwed gold caseback with sapphire crystal with anti-reflection coating on both sides, domed sapphire crystal with anti-reflection coating on both sides. Water resistant to 100 meters.
Dial: Matte silver-plated, minute track with applied dots, dauphin hands with diamond cut.
Bulova adds a new chronograph to its Joseph Bulova Collection, a set of automatic watches with designs inspired by Bulova watches made in the decades between 1920 and 1950.
This latest addition to the retro-themed collection is a three-subdial, 42mm steel-cased chronograph offered with either a black dial with rose-gold tone accents or a silver white dial with blue-tone accents.
While the new watch is larger than the original, and it now shows chronograph timing using three sub-dials instead of two, the new model retains several features that contributed to the character of the original watch.
The original features retained by Bulova include the telemeter scale around the perimeter of the dial, a domed crystal, railroad-track scales around the subdials and distinctive, squared chronograph pushers. In addition, Bulova has transferred the dial font and hand style from the original onto the new Joseph Bulova chronograph.
Of course, updates for both aesthetic and technical reasons are inevitable. For this piece, these include using anti-reflective sapphire to create the domed crystal, a day/date window and an exhibition caseback, exposing the rotor. Inside you’ll find a Swiss-made Sellita SW-500 chronograph caliber with a 48-hour power reserve.
Bulova is offering either style on a black leather strap engraved with Joseph Bulova’s signature on the inside. Finally, Bulova offers each watch in the Joseph Bulova collection as a limited edition of 350. Price: $2,495.
Alongside a new dive watch (Diver X Skeleton) and a new chiming watch (the Blast Hourstriker), Ulysse Nardin just ahead of Watches & Wonders 2021 debuts UFO, a table clock that literally rocks as it displays time on three dials, all under a glass dome.
We’ll provide details about the watches in upcoming posts. Below we help you identify the new Ulysse Nardin UFO.
Teaming with Swiss clockmaker Maison L’Epée, well known in recent years for its whimsical collaborations with pioneering independent watchmaker MB&F, Ulysse Nardin has constructed UFO, a sixteen-pound, 10.3-inch tall aluminum and glass clock built with a rounded base that allows the clock to swing from side to side like mechanical waves around its axis. The UFO swings up to 60° from its axis – an amplitude of 120 degrees, with no affect on its precision.
The UFO, or unidentified floating object, is the futuristic interpretation of what Ulysse Nardin’s designers, engineers, and watchmakers think a marine chronometer should look like in 175 years, according to Ulysse Nardin CEO Patrick Pruniaux. “We always look ahead,” he says. “We wondered what a marine chronometer designed in 2196 would be like.”
The clock’s imbalance and swinging motion is meant to conjure images of the perpetual movement of the ocean. Ulysse Nardin’s 175-year history, which this clock honors, includes more than a century of making award-winning marine chronometers.
Glass and dials
The clock’s ‘imbalance’ starts with a blue half-spherical aluminum base fitted with a tungsten mass. The base and glass bell are connected to a bayonet mounting system, which echoes marine chronometer construction where the top glass could be unscrewed.
Romain Montero, a 26-year-old artisan glass blower who works for the Swiss-based Verre et Quartz, a technical glass-blowing workshop near Lake Neuchâtel, creates each glass cover by hand. The process is labor-intensive, and for each cover finished, two others were attempted without success, according to Ulysse Nardin.
L’Epée requires 663 components, and plenty of time, to build each UFO, with the three trapezoidal dials being among the clock’s most complex components to construct. According to the manufacturer it takes twenty-eight hours to manufacture eight of the dials. Three are placed into the UFO, which allows the owner to display three different time zones at once, each seen from a different angle.
The three blue-hued dials face outward around the top the clockworks, which are fully visible. And among the many spectacular sights within the clock are the six massive barrels that confer an incredible year of power reserve when fully wound with forty turns of a key. Each dial has its wind-up notch, which is also used to the set the time (four notches in total, one for winding up and one for each time zone wound up using a single key).
At the top of the movement L’Epee and Ulysse Nardin have installed a dramatic slow-beat, large-diameter (49mm) brass balance wheel. The size and the leisurely 3,600 bph frequency (one per second) of the balance is meant to both soothe the viewer while also contributing to movement’s ultra-long power reserve. And to put a finer point on the clock’s meditative rate, you’ll find a dead-beat second indicator just below the balance.
Specifications: Ulysse Nardin UFO
Movement: UN-902 caliber table clock, manually wound movement displaying three time zones, hours, minutes, deadbeat second, 675 components, six barrels, extra-large oscillator (49mm),0.5 Hz /3,600 Alt/H, one-year power reserve.
Case: Aluminum and blown glass measuring 263mm (H) x 159mm. Weight: 15.8 pounds, 75 timepieces
Greubel Forsey debuts its first metal bracelet today as it adds contemporary updates to its titanium GMT Sport. The all-new, fully integrated titanium bracelet echoes the new look of the unusual elliptical bezel, complete with the high level of hand finishing you’d expect from Greubel Forsey.
You might recall that when this high-end watchmaker first showed the world the GMT Sport in 2019, the watch’s distinctive ovoid bezel attracted just as much attention as the watch’s new movement featuring such Greubel Forsey specialties as a Tourbillon 24 Seconds and eye-catching three-dimensional GMT globe.
Likewise, the new bracelet here might garner outsized attention given its premiere status for this brand. Greubel Forsey has devised a three-link bracelet finished with many of the same styles we see on the 45mm-by-15.7mm case and bezel, notably straight graining, frosting and top-tier hand-polished beveling.
Greubel Forsey notes that it opted to frost-finish the lugs to better emphasize how the case and bracelet link directly along an uninterrupted row. The somewhat darker frosting continues along both edges of the bracelet as well, underscoring the visual unity of the two components.
Functionally, the bracelet features a fine adjustment system that allows the wearer to quickly loosen or tighten the bracelet’s fit. The watch will also arrive with a blue rubber strap with text in relief and a titanium folding clasp with engraved logo.
While adding a bracelet to the GMT Sport, Greubel Forsey has also removed something: The GMT Sport’s wide, undulating bezel is now free of the raised engraved text espousing the brand’s values. Instead, the elliptical bezel, which curves gently at 12 o’clock and 6 o’clock, is cleaner, sporting expert hand-finished horizontal straight graining on top and a hand-polished frame.
Thus, instead of reading words like ‘perfection’ and ‘harmonie’, the wearer can focus on the GMT Sport’s intricate, multi-dimensional dial components and displays amid the bright new blue and titanium color scheme.
Indeed, the new color scheme of this GMT Sport highlights a matte blue finish on the mainplate, bridges, globe, second time zone dial and 24-second indicator ring of the Tourbillon 24 Seconds. The color nicely contrasts with the polished components of the steel and titanium movement components.
In addition, to draw attention to new blue color scheme, Greubel Forsey has decided to skeletonize the highly visible central suspended arched bridge and the tourbillon bridge.
The blue color splashes across the multi-level dial plates, replacing the dark grey hue of the previous GMT Sport. Between the blue plates wearers can check the time via a central hours and minutes display while eyeing a second time zone at 10 o’clock, a power reserve indicator at 3 o’clock and the GMT rotating terrestrial globe at 8 o’clock.
The GMT globe, first seen in 2011 and used within the GMT Black in 2015, displays the second time zone (as seen on the auxiliary dial just above at 10 o’clock). When the wearer combines this with the globe’s universal time display, he or she can read the current time anywhere in the world. And of course a wearer can enjoy the whirling Tourbillon 24 Secondes, positioned between 12 o’clock and 2 o’clock, which contributes to the watch’s high level of precision.
Greubel Forsey will make the new GMT Sport with the new titanium bracelet in a limited edition of thirty-three units. The price has not yet been announced, though the previous GMT Sport was priced at $500,000.
Specifications: Greubel Forsey GMT Sport
Features: In titanium, blue movement, limited edition hand-wound movement with three patents, GMT, 2nd time zone indication, rotating globe with universal time and day-and-night, universal time on 24 time zones, summer and wintertime indication, cities observing summer time, 24-second tourbillon, hours and minutes, small seconds, power-reserve indictor.

Case: 45mm (with bezel) by 17.8mm (with crystals) titanium with curved synthetic sapphire crystal, three-dimensional, variable geometry-shaped bezel, hand-polished with hand-finished straight graining, 100-meter water resistance. O back is a sapphire disc displaying city names surrounded by 2 rings
Bracelet: New three-row metal bracelet in titanium, folding clasp with integrated fine adjustment, engraved GF logo. Also: rubber with text in relief, titanium folding clasp, engraved GF logo.
Frederique Constant this week unveiled a groundbreaking one-piece silicon oscillator that effectively replaces the traditional mechanical movement’s twenty-six-piece escapement assortment, and has developed a new movement around the high-tech component. The new movement, automatic Caliber FC-810, will power the Slimline Monolithic Manufacture Collection of 40mm watches, available this September.
Debuted after three years of research and development, Geneva-based Frederique Constant’s new oscillator beats at the ultra-high rate of 288,000 vibrations per hour, or 40 Hz, about ten times faster than traditional mechanical movement oscillators. And since it is created as a single friction-free, anti-magnetic, lightweight component, both the oscillator and the movement demonstrate ultra high efficiency.
As a result, when teamed with a standard winding spring in the new movement, watches in the new Slimline Monolithic Manufacture collection realize a full eighty-hours of power reserve.
Frederique Constant teamed with Nima Tolou, CEO of the Netherlands-based micro-engineering firm Flexous, to develop the silicon oscillator. Frederique Constant’s watchmaking department asked Flexous to develop a unique, flexible oscillating system in a size comparable to a traditional balance. Furthermore Frederique Constant set specifications, including: the highest possible frequency; an 80-hour power reserve; and a cost-effective formula allowing the manufacture of significant quantities at a reasonable price.
Flexous met the requests, devising a component that measures 9.8mm in diameter and 0.3mm thick, approximately the size of a conventional regulator. As noted above, the new oscillator incorporates all twenty-six components that make up the typical assortment, including the traditional balance, spring, anchor and rubies. And, echoing the traditional escapement, the new oscillator’s frequency can be fine-tuned by adjusting two tiny weights.
The first collection Frederique Constant is fitting with the new movement is the Slimline Monolithic Manufacture, a three-hand watch with a pointer date. The 40mm round watch offers a classic Swiss dress dial with a central guilloché hobnail pattern, printed Roman numerals and Breguet-style hands.
The design of the Slimline Monolithic Manufacture echoes the brand’s pioneering use of open dials that expose portions of the movement. When it debuted in 1994, the Frederique Constant Heart Beat was the only serially produced non-skeleton Swiss-made collection that boasted an open dial.
Where that collection displayed the automatic caliber’s escape wheel at the 12 o’clock position, the new collection displays the new pulsating silicon oscillator through an aperture at 6 o’clock.
On the reverse side, a clear sapphire caseback offers an unimpeded view of the automatic FC-810 caliber, which is Frederique Constant’s thirtieth in-house movement. The brand decorates the movement with traditional Geneva stripes with perlage; the oscillating weight is open worked.
Frederique Constant will make the Slimline Monolithic Manufacture in three limited editions, projected to be shipped starting in September. The editions include 810 pieces in stainless steel with a blue dial ($4,795) and 810 pieces in a steel case with a silver color dial ($4,795). Also, an 18-karat gold model with a silver-colored dial will be made as a limited edition of 81 pieces ($15,995).
Ten years after debuting its first Legacy Machine, ground-breaking independent watchmaker MB&F debuts LMX, a new dual-dial Legacy Machine that echoes the premiere Legacy Machine, but with new dial angles, a dual-display power reserve indicator and updated precision.
Like the first MB&F Legacy Machine, the new LMX also features two white lacquer dials displaying hours and minutes in two different time zones. But where those dials were flat on that first model, the two white dials on the new LMX are tilted at an angle, much like dials we’ve seen on the MB&F LM Flying T and LM Thunderdome. This meant MB&F needed to add conical gearing to the movement in order to transfer the energy from the horizontal movement to the tilted dials.
Where the first Legacy Machine featured a somewhat traditional dial plate, the new LMX shows off its battle-axe-shaped escapement bridge and components of the gear train. Specifically, MB&F exposes three large wheels, namely the two gears that rotate when setting each dial, plus the gear at 6 o’clock, which is the common seconds wheel.
New power indicator
Also new is a much more complex power reserve indicator. While the first Legacy Machine itself broke new ground with a three-dimensional power reserve display, the LMX offers a nod to that debut with a three-dimensional, hemispherical display that is also customizable.
The wearer can select between two modes of counting down the power reserve. MB&F places two markers on opposite sides of the hemisphere. One features a scale numbered from one day to seven days, and the other scale shows the days of the week.
The new display, likely the first of its kind on a wristwatch, allows wearers to choose their preferred mode of power-reserve indication.
Finally, MB&F has built a new balance wheel for the LMX. The exposed balance, hanging from arched titanium bridges, is for many the primary characteristic of the first Legacy Machine and is repeated throughout the decade-long Legacy Machine lineage. MB&F has built a new balance wheel measuring 13.4mm in diameter with inertia blocks rather than more traditional screwed balances. MB&F explains that this choice “offers greater accuracy to the watchmaker in regulating the heart of LMX.”
MB&F is offering the new LMX in two limited launch editions:
– Eighteen pieces in red gold with black NAC treatment on plates and bridges ($128,000);
– Thirty-three pieces in titanium with green CVD treatment on plates and bridges ($112,000).
Specifications: MB&F LMX
Movement: MB&F three-dimensional manual winding with three mainspring barrels. Power reserve of 7 days (168 hours), new 13.4mm balance wheel with inertia blocks floating above the movement. Balance spring is traditional Breguet curve terminating in mobile stud holder; balance frequency is 18,000bph (2.5Hz), gold chatons with diamond countersinks, superlative hand finishing throughout respecting 19th century style; internal bevel angles highlighting hand craft; polished bevels; Geneva waves; hand-made engravings; polished arms of the straight bridges exposed on the dial plate, manually finished to a curved “bercé” profile on their upper surfaces.
Dial: Completely independent dual time zones displayed on two dials. Unique hemispherical power reserve with choice of weekday or 7-day indication; rotates to adjust the preferred power reserve indication. Left crown at 10 o’clock for setting time of left dial; right crown at 2 o’clock for setting time of right dial and winding.
Case: 44 mm wide x 21.4 mm in two launch editions: 18-karat 5N+ red gold case limited to 18 pieces or grade-5 titanium case limited to 33 pieces. High domed sapphire crystal on top and sapphire crystal on back with anti-reflective coating on both sides.
Strap: Black hand-stitched alligator strap with 5N+ gold folding buckle for red gold version, and grey hand-stitched alligator strap with titanium folding buckle for titanium edition.
Among its range of 2021 debuts, Grand Seiko adds a new 40mm platinum-cased model within its vintage-inspired Heritage collection. The new watch, called the Grand Seiko Heritage Collection Seiko 140th Anniversary Limited Edition (SLGH007), features the Caliber 9SA5, the brand’s superb new high-beat movement, and a dial meant to echo the beauty of tree grain, or rings.
The watch debuts amid a 2021 Grand Seiko launch that also includes a new Spring Drive chronograph, a set of Elegance dress watches with dials inspired by the seasons, and a Spring Drive high jewelry model. We’ll show you details about these pieces in upcoming posts.
With its intricate depiction of tree grain, the new limited edition is meant to embody Seiko-founder Kintaro Hattori’s spirit and vision. “As if stretching back to reveal the very roots of Kintaro’s story, a series of delicate and organic lines echo the intricate rings that denote each year’s growth,” according to the brand.
Grand Seiko artisans have devised a dial with a three-dimensional appearance enhanced by how light plays off textural undulations. The wood grain effect appears realistic thanks to a subtle use of dark and light tones across the dial.
Grand Seiko says it plans to echo the design of this new model in the future, dubbing it Series 9, which will feature the larger hands designed to align exactly with grooved hour markers. In addition, this model offers its platinum case finished with a hairline pattern matched with a mirror finish.
As an anniversary piece, the watch’s precious metal is celebrated. On the dial, Grand Seiko places a star at six o’clock to indicate that the indexes are solid gold, as are the GS letters, the calendar frame and the buckle.
Inside, the Grand Seiko Caliber 9SA5 is billed by the brand as its finest – and for many reasons. Primarily, the movement is thinner and is more efficient than earlier automatic calibers, attributes driven in part by a wholly new Dual Impulse Escapement. This Grand Seiko invention combines direct impulse, where power is transferred directly from the escape wheel to the balance, with conventional indirect impulse. Twin barrels also enhance the caliber’s top-rate 80-hour power reserve.
The Grand Seiko Heritage Collection Seiko 140th Anniversary Limited Edition will be available as a limited edition of 140 at the Grand Seiko Boutiques and selected Grand Seiko retailers worldwide in July 2021. Price: $59,000.
Movement: Automatic ‘Hi-Beat’ 36000 80 Hours Caliber 9SA5 , 36,000 vph (10 beats per second), accuracy (mean daily rate): +5 to –3 seconds per day, power reserve of 80 hours.
Case: 40mm by 11.7mm platinum 950 case and clasp, box-shaped sapphire crystal with anti-reflective coating, see-through screw caseback, water resistance to 100 meters, magnetic resistance of 4,800 A/m.
Strap: Crocodile with three-fold clasp with push-button release.
