The patterned white dial on the latest model within Grand Seiko’s Elegance Collection is meant to evoke the beauty of freshly fallen winter snow outside its watchmaking studios in the wooded Shinshu region of central Japan. That particular scene is known as Shizuri-yuki, which refers to the moment when snow spills down from the branches of trees to create a shimmering cascade of light.
The new Grand Seiko Spring Drive SBGY008 could be considered the next in a series of Spring Drive debuts with dials meant to evoke the beauty of winter just outside the Grand Seiko studio.
You might recall the Grand Seiko Spring Drive SBGY007 we showed you earlier this year, with its hammered ice-blue dial that beautifully mimics a nearby frozen lake, a phenomenon called Omiwatari.
Grand Seiko cases this latest Elegance watch in a 38.5mm rose gold frame dotted along its sides with fifty-three hand set diamonds. Artisans nicely arranged the gems so that they gradually decrease in size from the center of the case to the end of the lugs, which appears to flow along the side of the case. This quite effectively generates the namesake Shizuri-yuki sparkle.
Grand Seiko then continues to evoke the winter scene on the dial with a wind-blown snow pattern. The scene is broken only by the very smooth Spring Drive seconds hand, and much more slowly as hour and minutes pass as indicated by matching, perfectly faceted gold hands.
This is a fairly thin watch, measuring 10.2mm in depth, thank to Grand Seiko’s own Spring Drive manual-wind caliber winding Caliber 9R31, which offers an impressive 72 hours. As a Spring Drive caliber, it also provides incredible precision with accuracy rated to ±1 second per day.
The Grand Seiko Spring Drive SBGY008 is sold on a brown leather strap and comes with an additional satin gold-colored leather strap (above). The watch will be available as a limited edition of sixty at Grand Seiko Boutiques and selected Grand Seiko retailers worldwide in January 2022, just as winter peaks in the northern hemisphere. Price: $38,000.

Grand Seiko’s latest additions to its Elegance Collection include these two unisex 34mm models (SBGX347 and SBGX349). Each watch sports this brand’s characteristic and highly light-reflective diamond-cut markers and hands. Grand Seiko sets a white or a royal blue dial within the slim (10.7mm) steel case with a thin bezel and boxed, retro-inspired sapphire crystal.
The watch’s straight-forward design belies a great deal of technical detail, including the use of Caliber 9F61, Grand Seiko’s famed high-end (and hand-assembled) quartz caliber with an ultra-precise accuracy of +/-10 seconds a year.
And Grand Seiko protects this movement against potentially destabilizing magnetic influences to an especially strong level of 4,800 A/m, not typical protection among watches in this price range.
Both Grand Seiko Elegance debuts are priced at $3,300.

Seiko’s partnership with the U.S.-based sports clothing and accessories brand Rowing Blazers, announced earlier this summer, resulted in three colorful automatic Seiko 5 Sports watch designs. Two of the watches are limited editions and one model is an ongoing ‘special edition.’
The collaboration offers three distinctive bezels on a 42.5mm steel case with a black Seiko 5 Sports day-date dial with its crown at 4 o’clock. The collaboration includes an unusual red and white seconds hand alongside the Seiko 5’s characteristic wide hour and minute hands.
Also new here is the Rowing Blazers logo on the dial. Inside Seiko fits its ultra-reliable automatic Caliber 4R36 with 41-hour power reserve.
The collection, developed in collaboration with Rowing Blazers founder and creative director Jack Carlson and Seiko’s product development team, features three unidirectional bezel designs: a checkered rally pattern (SRPG49), a red zigzag Rowing Blazers motif (SRPG51) and a four-color red, blue, yellow and green design (SRPG53).
(See our interview with Carlson below for insight into how and why he designed the Seiko-Rowing Blazers collection.)
The latter design is on the special edition model that is not limited in number. Seiko includes a rainbow, green or black nylon strap with each steel bracelet watch.
“Collaborating with Seiko is a dream come true,” says Rowing Blazers founder Jack Carlson. “I have a small collection of both new and vintage Seikos, and I’m obsessed with the brand. This is our first real foray into the world of watches — though we often sell vintage Seikos on our site — and I couldn’t imagine a better partnership.”
As a bonus, each watch is emblazoned on its caseback with a skeleton as a reminder that time flies (a memento mori). Price: $495.
Seiko’s Seismic Shift
By James Henderson
By the time you will read this, what has been perhaps one of the most seismic shifts in the ever-growing watch subculture that is the Seiko 5 Sport series will have already happened. In fairness, there have been and will continue to be Seiko 5 Sports models put out in limited edition series. That being said, the majority of them are targeted to a decidedly wider, easier to sell-to demographic.
More to the point, Rowing Blazers has built its fan base (I am a proud member) by decidedly swimming against the current of the obvious. So while it would have been easy to take a basic watch and throw the Rowing Blazers name on it, the Rowing Blazers Seiko 5 capsule did something more.
Rowing Blazers founder Jack Carlson and vintage watch expert Eric Wind rolled up their sleeves and came up with not one, not two, but three unique watches that got watch fans in North America and beyond so worked up that they sold out faster than Wonka bars when everyone was looking for golden tickets.
Although your best chance to get one of these nifty time machines is to scour the various secondary market places, the powers that be here at Isochron Media thought you might enjoy a bit of background on what has proven to be the Seiko 5 equivalent of what happened when the guy said “What if we sliced the bread before we sold it?”
Not unlike when Smith met Wesson, you and Eric Wind have a bit of a story. How did you two meet?
Jack Carlson – Eric and I met on the first day of our freshman year in college, at Georgetown in 2005. We became fast friends. I even persuaded Eric to try out for the rowing team. Eric’s rowing career was brief, but we remained great friends. We were both in the School of Foreign Service; Eric was studying Farsi, and I was studying Chinese.
After Georgetown, I did a PhD at Oxford in archaeology, and while I was there, Eric popped over for a year to do a one-year MBA. I was honored to be the best man at Eric’s wedding to his amazing wife Christine. Aside from being a great friend, Eric has also been my watch consigliere and a great supporter of the Rowing Blazers brand since we launched four years ago. Eric sources and curates many of the vintage watches we sell at Rowing Blazers, and, of course, we also worked together on the Seiko collaboration!
What was the inspiration for the capsule?
I love Seiko, and I’ve been a vintage Seiko collector for a while now. So, it was an honor to have the opportunity to work together. I wanted everything we created to feel timeless, classic, and wearable. But I also wanted them to be fun, a little unexpected, and a little irreverent.
Color and pattern are very important to Rowing Blazers as a brand; and I wanted the capsule to reflect that. The four-color bezel was just something I’ve wanted to do for a long time. It’s so simple, but also fun and unique. It’s a very ‘90s vibe, very nostalgic, like a lot of what we do at Rowing Blazers.
The Rally bezel is inspired by some of my favorite vintage Seikos. Whenever we collaborate with a brand with a rich history and heritage like Seiko, I always try to tap into that history, and to bring some aspects of it that might not be getting a lot of love or attention currently to the surface. And the zig-zag artillery stripe is one of our brand codes. We’ve never rendered it in a circular format before, but it came out brilliantly.
Why the Seiko 5?
The Seiko 5 Sports are a great canvas to work on. We can do a lot of fun things, and the result is still classic, wearable, and a relatively accessible price point, which I think is great for our first watch collaboration.
Are there possible future collaborations?
Yes! Several exciting things in the works! Stay tuned!

Grand Seiko artisans use a variety of manufacturing and finishing techniques to create the dial, including stamping, plating and hand painting.
Named to celebrate Seiko’s 140th anniversary, the watch’s stunning and highly engraved 38.5mm platinum case also expresses the natural clarity of Achi’s night skies. Pleasing groups of leaf-like patterns cover the entire case, repeated in varying directions to capture “the exquisite order and ever-changing aspect of Achi’s starry skies,” according to Grand Seiko.
Inside Grand Seiko fits it superb Spring Drive manual-winding caliber 9R02, a movement first seen in 2019 when it marked the 20th anniversary of Spring Drive.
The movement itself continues Grand Seiko’s ode to natural beauty. For example, the barrel is shaped to echo the bellflower that is the symbol of the Shiojiri region, home to the Micro Artists Studio. Next to the barrel is the power reserve indicator.
The power reserve here is an impressive eighty-four hours, largely thanks to the Caliber 9R02’s Dual Spring Barrel. Not surprisingly, Grand Seiko expertly hand polishes the rims of all the bridges, the holes for the rubies and the screws.
Note the 18-karat yellow gold plaque on the lower bridge. While it is marked with the engraved words “Micro Artist,” Grand Seiko allows the owner of the watch the option to replace these words with a phrase of his or her choice. Available starting in August, the watch is a limited edition of fifty. Price: $79,000.

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.

Among Seiko’s wide-ranging 2021 debuts, two new Prospex models stand out for near-perfect fidelity to the original Seiko watches that inspired their re-interpretation. One, the Seiko Prospex Alpinist, revisits a Seiko sport model from 1959, while a second, the new Seiko Prospex Naomi Uemura 80th Anniversary Limited Edition, revisits a historic dive watch Seiko made in 1970.
What makes both these debuts even more vital for Seiko collectors, and sports watch enthusiasts in general, are the updated collections based on these historic designs.
As worn by Japanese adventurer Naomi Uemura in the mid-1970s when he completed a 12,500-kilometer solo dog-sled run from Greenland to Alaska, a 1970 Seiko dive watch offered both reliability and protection. The watch was also notable for its unusual asymmetrical extension that protected the crown at the four o’clock position.
Revisiting that 1970 design, Seiko in 2021 offers two new 44mm steel models. One (Reference SLA049) is a limited edition of 1,200 watches that echo the case’s original shape, high-visibility and three-hand dial, but now offer a special ‘mountain-pattern’ blue dial and blue bezel, said to recall the “blue tones of the earth’s upper atmospheric layers.”
Seiko of course has modernized the tribute watch in several ways, primarily with the updated movement. Inside you’ll find Seiko’s dive-centric Caliber 8L35, made at the Seiko Shizukuishi Watch Studio in northern Japan.
The dial is also extra luminous, with all hands and all hour markers coated generously with Lumibrite. Seiko has also coated the case with a protective, anti-scratch layer, and has placed an anti-reflective coating on the dual-curved sapphire crystal.
Finally, Seiko has increased the watch’s water resistance, now rated to 200 meters. For this limited model, Seiko includes a blue silicone strap that has the same train-track pattern as the original model.
In addition to the blue-dialed limited edition that commemorates the 80th anniversary of Naomi Uemura’s birth, Seiko adds a gray dialed version to the Prospex collection. The watch shares the same textured pattern dial as the limited edition but is in a charcoal gray color that is similar to the 1970 original. It shares the same case design, features and specifications as the commemorative watch and will also be available at the Seiko Boutiques and selected retail partners worldwide in July 2021.
Seiko introduced its first watch made for mountain climbers in 1959. Called the Seiko Laurel Alpinist, it marked the start of Seiko’s march into the much broader sports watch market. Seiko followed that debut model with a series of watches specifically tailored for sports, including stopwatches and diver’s watches.
For 2021 Seiko revives that debut 1959 design with two odes to the original. One, the Seiko Prospex 1959 Alpinist Re-creation, is a 36.6mm limited edition that retains the original’s dial markings and its sporty leather cuff. A second model, the Seiko Prospex 1959 Alpinist Modern Re-interpretation, is slightly larger, at 38mm, is fitted with a different movement and is offered on steel bracelet (and two dial options) and on a leather strap.
Seiko Prospex 1959 Alpinist Re-creation
The re-creation brings back the black dial and large markers found on the original, but now adds a date window and stronger water resistant (to 100 meters). In addition, its box-shaped sapphire crystal is now treated with an anti-reflective coating on the inner surface. Finally, the movement is updated with Seiko’s thin automatic Caliber 6L35, which has a power reserve of 45 hours. Despite the addition of a date and the new automatic caliber, the case is just 1.0mm thicker (11.1mm) than the original model. And of course, Seiko has faithfully reproduced the leather strap and cuff, using the same jagged stitch design as its predecessor.
The re-creation will be available as a limited edition of 1,959 at the Seiko Boutiques and selected retail partners worldwide in August. Price: $2,900.
Prospex 1959 Alpinist Modern Re-interpretation (below)
The three other new watches that pay homage to the 1959 Alpinist sport a more contemporary dial treatment and offer a choice among two steel bracelet models and one attached to a leather strap. This collection of three models is one of Seiko’s best values among all its 2021 debuts.
Their slightly larger (38mm) polished cases are notably more modern than the Re-creation, and the Caliber 6R35 offers a stronger power reserve, at 70 hours. In addition, the water resistance is to 200 meters, twice the rating of the Re-creation. Two watches (cream-colored dial and black dial) are offered on stainless steel bracelets while the green dial version comes with a leather strap.
All three of these Prospex 1959 Alpinist Modern Re-interpretation watches will be available at the Seiko Boutiques and selected retail partners worldwide in August. Prices: $750 and $725 (leather strap).
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.
It goes without saying that Dive Watches are one of the most popular styles of men’s watches sold today. But what many don’t know is that invoking the “dive” moniker actually has legal implications. Writing the word “Divers 200M” or any similar mark with “Diver” written on the dial or case back immediately invokes ISO 6425. The ISO (International Organization for Standardization) is an international body that writes standards for the commercial industry.
Before we get into ISO 6425, let’s talk about dive watches first. In modern times, very few SCUBA divers actually rely exclusively on a wristwatch while underwater. As an example, my own dive master had a beautiful Rolex Submariner on his wrist during classroom lessons, but once we hit the water, the Rolex was replaced with a dive computer.
Before the advent of these modern and multi-function computers, divers relied on their mechanical watches to keep track of the key data points of total time submerged as well as bottom time in order to calculate residual nitrogen in the blood, and determine when, how many, and how long decompression stops should be if needed.
The dive watch, in this case, was performing a critical function, where a malfunction could spell disaster for the diver. This is why the ISO spec was developed, because dive watches were so critically important as instruments that protected the user’s health and safety. Today the analog dive watch continues to be worn while diving, but is more of a fashionable backup in the unlikely case the computer fails.
ISO 6425 is a rigorous specification titled “Horology – Divers’ watches” that supersedes older specs first released in the mid 1990s. In essence, it spells out what qualities a Dive Watch must have, and the methods with which to test them.
Among the tests that ISO 6425 calls for includes, but is not limited to; temperature extremes, day and night visibility, magnetic resistance, salt spray, shock resistance and of course, water resistance. Obviously, we all expect water resistance to be one of the parameters checked. However, since water resistance is so important to the function of the dive watch, the actual pressure (depth) to which the watch is tested is 25% beyond the stated water resistance limit of a particular watch.
For example, a dive watch rated to 200 meters (20atm) is actually tested to 250 meters in order to meet ISO 6425. And it’s not a dry air test. It is a true wet test, with a follow up condensation test to see if any moisture has found its way into the watchcase.
Furthermore, ISO 6425 states that EVERY watch certified to the spec needs to have its own water resistance individually tested. This means that if you are wearing a watch bearing the “Divers” mark on the dial or case back, that particular watch has been tested to 25% beyond the depth stated on the dial. Not a sample, but the very piece you are wearing. This is the ONLY way to ensure it will perform flawlessly under the stresses of diving.
On my YouTube channel I discuss ISO in detail in my Watch and Learn series. In addition to water resistance, another ISO test that was actually quite fun to perform was the requirement that the strap needs to withstand about forty pounds of pull (simulating getting snagged on something) without the spring bars popping or tearing the strap itself. It was a great test to replicate, and the results were pretty eye opening.
So the next time you see the word “Dive” on watch dial, you’ll know that you are looking at an individually proven and tested dive watch that meets or exceeds the ISO 6425 quality standard!
Thank you for reading, and thank you for watching.
Grand Seiko artisans have applied the deep brown color of the eagle’s feathers to the dial and bezel of the Spring Drive GMT SBGE263, which the brand says are meant to recall the “warm tones of the earth – reliable and dignified.”
Continuing its ode to the eagle, Grand Seiko also devised the watch’s radiating dial pattern to represent the bird’s flight, while the gold arrow of the GMT hand is “reminiscent of the eagle’s powerful beak.” The watch’s 40.5mm steel case features a contrasting mix of Zaratsu-polished and hairline surfaces.
As a GMT watch in the truest sense, powered by Spring Drive Caliber 9R66, the watch allows the wearer quick access to a second time zone. With the caliber, the local hour hand is independently adjustable while the GMT hand remains fixed to home time. This means that when the wearer arrives at new location in a different time zone, he or she can simply jump the hour hand to the correct hour without having to reset the watch.
The watch is offered as a U.S. limited edition of 110 and will be available in January at Grand Seiko Boutiques and for members of the newly expanded GS9 Club, now open to members in United States. Price: $6,700.
Specifications: Grand Seiko Spring Drive GMT ‘Eagle’ U.S. Limited Edition SBGE263
(Limited edition of 110)
Movement: Caliber 9R66 Spring Drive, accurate to +/-15 seconds month (when static), power reserve of 72 hours.
Case: 40.5mm by 14.7mm steel, brown ceramic bezel, dual curve sapphire crystal, water resistant to 200 meters.
Dial: Ridged pattern brown, raised and beveled markers.
Two brand-new releases from Seiko Prospex recall historic diver’s models from 1968 while a third new diver’s watch, offered on a silicone strap or a titanium bracelet, features a lighter titanium dial and a bracelet built with references to a Shogun’s helmet and armor.
Seiko has updated both models with the solid 6R35 automatic mechanical movement, which is appreciated for both its robust nature as well as its 70-hour power reserve.
Bi-directional winding via the magic finger system adds power to the movement while wearing the watch, but you can also manually wind it as well. Also, for all the watch “hacks” out there fixated on stopping the second hand in order to coordinate their next mission, the 6R35 does in-fact offer this over-appreciated feature.
While critics may search for other depredations in the fact that the frequency of the caliber 6R35 at 21,600 vph is a bit slower than other Japanese options, accuracy is the same or similar to those slightly faster mechanical heartbeats. One wonders if the internet’s instant experts have considered that putting less stress on a system that will inevitably need service and/or repair down the road might actually be a benefit rather than a detriment.
Seiko fits this movement into its Propex “Shogun” series (SPB189 and SPB191) are crafted in a 43.5 mm hardened titanium case rated to 200 meters of water resistance with the crown at the traditional 3 o’clock position. A super-huge date display is made even larger by a magnifying cyclops window, with a uni-directional diver’s bezel atop. The sapphire crystal over the dial will be difficult to mar or scratch unless you shatter it entirely.
Like its sister dive models, the Seiko Prospex ‘Shogun’ could not be any easier to read; Broad hands coated in a thick layer of LumiBrite glow brightly – just like the hour markers. Time is clearly of the essence with these masterful classics. Offered with a choice of a silicone strap at $1,350, or a titanium bracelet for an extra $200, the Shogun will be a fan favorite for both real and “desk” divers.
For Japanese warrior fans, Seiko says the triangular notches in the rotating bezel on this model resemble the ornaments of a traditional Shogun helmet. The yabane or “arrow feather” link shape of the bracelet version, according to the brand, calls to mind weapons and armor.
Bringing us back to 1968, the Seiko Prospex Diver SPB185 and SPB187 are slightly smaller at 42mm, slightly heavier as they are cast in steel, and slightly less expensive due to the aforementioned reasons.
Broader shoulders separate the sister-types, as does a crown migrated slightly south to the 4 o’clock position. Other nuances of design define each as the hands, markers, and bezel are endemic to each design. Otherwise these are very similar in the chassis build quality. Available only on a solid link steel bracelet, the 185 and 187 retail for $1,200.
