Hublot extends its already wide-ranging collection of ceramic-cased watches with its first minute repeater entirely cased in the high-tech material. The new Big Bang Integral Minute Repeater Ceramic, a 43mm model in white or black ceramic, joins the firm’s Integral Ceramic collection, which debuted in 2020.
Beyond its in-house distinction, the new Big Bang Integral Minute Repeater Ceramic is also the first watch of its kind (a tourbillon minute repeater) made by any watchmaker that has been cased entirely in ceramic, according to Hublot.
Like its brethren in the Integral Ceramic collection, the new watch is made with an all-ceramic case (here at 43mm) and with an integrated all-ceramic bracelet, bezel and case back. And the new watch also is Hublot’s first model regulated by a tourbillon within the collection.
Inside Hublot fits its own existing manual-wind MHUB801 caliber with eighty hours of power reserve. The watchmaker will make eighteen watches in black ceramic and eighteen in white ceramic.
Hublot has placed minute repeating movements into numerous watches in the past, sometimes also paired with a tourbillon. You might recall that in 2014, Hublot received a Grand Prix d’Horlogerie de Genève (GPHG) for its Classic Fusion Cathedral Tourbillon Minute Repeater.

Patek Philippe underscores its reputation as the source for the finest minute repeaters with a new model, the Ref. 5750 Advanced Research Minute Repeater, an extra-loud chiming wristwatch that utilizes a new sound amplification system.
The Geneva watchmaker says its new watch delivers dulcet time-telling tones that can be heard up to 180 feet away from the wearer’s wrist.
Patek Philippe’s new system, dubbed ‘Fortissimo ff,” consists of a sound lever, or metallic ‘blade,’ that oscillates a sapphire crystal wafer located on the back of the watch. Patek Philippe’s Advanced Research arm has spent several years developing the Fortissimo ff and will place it into fifteen 40mm platinum-cased Ref. 5750 Advanced Research Minute Repeater watches.
The watchmaker says its new system, for which Patek Philippe registered three patents, essentially builds a novel pathway for the sound to reach the wearer’s ears. The hammers on the new model, built directly from the design of Patek Philippe’s famed caliber R 27 PS (from 1989), strike in a traditional manner on a titanium ring. Then the new ‘Fortissimo ff’ module takes over to amplify the tones.
The new design transmits the gong oscillations to the sapphire wafer, which, unlike a traditional repeater, is not connected to the case and vibrates on its own. This effectively amplifies the sound, sending it out through four openings at 12, 3, 6, and 9 o’clock in the titanium ring. A dust filter protects the movement.
As noted, the resulting chimes can be heard up to 180 feet away from the watch, according to Patek Philippe. Traditional repeaters become difficult to hear approximately when listening thirty feet from the watch.
Platinum case and components
Since the sound waves created using the new ‘Fortissimo ff’ technology never touch the watch’s case, the case metal for the watch does not affect the sound.
However, Patek Philippe did make several metal changes to the movement design when compared to the slide-activated Ref. 5178 minute repeater, which served as the inspiration for the new Ref. 5750.
The watchmaker replaced the steel hammers found on the Ref. 5178 minute repeater with platinum hammers, which produce a softer strike. Furthermore, a mini-rotor in platinum replaces the original model’s gold rotor. With its greater material density, the platinum version delivers the same winding power but with a thinner design.
Patek Philippe tops its new watch with an openworked dial of contemporary design that differs considerably from the watchmaker’s generally classical minute repeater dials.
The watchmaker says spoked wheels of 1960s automobiles inspired the watch’s skeletonized dial. The primary dial is inset with a seconds subdial with a similar pattern. And in another break from Patek Philippe tradition, the seconds dial indicates seconds using a rotating disc rather than a traditional hand.
The watch is set with a shiny orange alligator strap with black seams and a platinum fold-over clasp. Patek Philippe will make fifteen platinum-cased Ref. 5750 “Advanced Research” minute repeaters. Price upon request.

Below we list the technical achievements of Patek Philippe Advanced Research division since its first results in 2005.
2005: Silinvar, a novel, patented material based on monocrystalline silicon. It was developed in collaboration with Rolex, the Swatch Group, and CSEM in Neuchâtel, and is suitable for applications in watchmaking. Also in 2005: First escape wheel in Silinvar. This new part improves dependability because it requires no lubricants. It also reduces the mass to be moved (better efficiency), is corrosion-resistant, and remains perfectly concentric.
2006: Spiromax balance spring in Silinvar, which optimized rate accuracy by improved isochronism thanks to concentric breathing (expansion and contraction) of the balance spring.
2008: Pulsomax escapement in Silinvar, which optimized geometry of escape wheel and lever and increased energy efficiency by 15%.
2011: Oscillomax ensemble (Pulsomax escapement with GyromaxSi balance and Spiromax balance spring) .
2017: Optimized Spiromax balance spring. Also, correctors with compliant mechanism in steel. This utilizes the elasticity of materials in microstructures and replaces articulations with pivots and leaf springs. This technical development offers numerous advantages: simplified assembly (12 parts as opposed to 37 previously), flatter design, no mechanical play, no friction, no arbor wear, which results in totally lubricant-free functionality and excellent energy efficiency.
Bulgari this week pays tribute to Gerald Genta with a renewed version of the famed designer’s Mickey Mouse watch. At the same time the watchmaker/jeweler adds a world time watch to its Octo Roma collection and revives a Papillon central tourbillon design, now set in an Octo Roma case. The original Papillon was a Daniel Roth jumping hour invention with ‘butterfly’ hands.
These debuts were just three Bulgari highlights at Geneva Watch Days 2021, where the Italo-Swiss watchmaker launched nine new models. These also included new models in the jeweled Divas’ Dream lineup and three Divina Mosaica watches, including one spectacular diamond-set model fitted with Bulgari’s thin minute repeater movement.
Gerald Genta Arena Retrograde with smiling Disney Mickey Mouse
Bulgari’s retro Retrograde watch, starring the world’s most famous mouse, pays tribute to the genius of Gerald Genta, who placed Mickey Mouse (and other Disney characters) on his own high-end watches starting in 1984. The Gerald Genta Mickey Mouse watches are today much sought-after by collectors.
You may recall that Bulgari in 2019 launched the first ode to Genta with its 50th Anniversary Arena Bi-Retro, which Bulgari released with only Gerald Genta’s name on the dial. Last year we saw a titanium version of the watch.
Those debuts recalled Bulgari’s acquisition of the Gérald Genta and Daniel Roth brands in 2000, a purchase that has played a significant role in building Bulgari’s haute horlogerie expertise.
Gérald Genta, who died in 2011 at the age of 80, designed many of the icons of modern watch design, including the Universal Genève Polerouter, the Audemars Piguet Royal Oak, the IWC Ingenieur, Cartier’s Pasha, the Omega Constellation, the Bvlgari Bvlgari and the Patek Philippe Nautilus. Many of these designs remain bestsellers for their respective brands.
This new Gerald Genta Arena Retrograde with smiling Disney Mickey Mouse marks the return of one of the most sought-after Genta designs. The watch’s debut also marks the next level in Bulgari’s ongoing reboot of the Gerald Genta line as its own brand. To accompany that expansion, Bulgari is developing a new Gerald Genta website.
The new watch almost perfectly mimics many of the original Gerald Genta designs, here nicely settled into 41mm steel Gerald Genta Arena case. In this version you’ll find Mickey showing the time amid an also-playful rhodium-plated sunray dial. Mickey’s left arm and white-gloved hand indicates the minutes on a 210-degree retrograde dial as a jumping hour indicator shows the hour at the 5 o’clock position.
Bulgari is making the Gerald Genta Arena Retrograde with smiling Disney Mickey Mouse as a limited edition of 150-pieces, all available only online at Bulgari. Price: 16,500 euros, with January 2022 delivery.
Octo Roma WorldTimer
Bulgari developed a new movement, Caliber BVL257, to power this world time watch, a first for the Octo Roma collection. And as a travel watch, it features instant reading of the time in twenty-four cities, which corresponds to the world’s primary time zones. This launch comes just days after the debut of another well-received Bulgari travel model, the Aluminum GMT watch.
Echoing classic world timer dial layouts, the Octo Roma WorldTimer offers a central display of the hours, minutes and seconds combined with a double rotating disc on the outer edge. One of the disks is set with the names of the reference cities while the second displays the 24-hour scale. When read in tandem, they allow the wearer to read the time in multiple time zones.
Bulgari took some liberties with the cities listed around the dial of this new watch, opting to swap the more common Bermuda for St. Barts, and representing cities where Bulgari has (or will soon have) one of its own hotels.
This sporty watch is built within the brand’ excellent multi-faceted Octo Roma 41mm steel case with a blue dial and matching steel bracelet. A stealthier version can be had in a black DLC case with a black textured rubber strap. Price: $8,350.
We’ll have more details about Bulgari’s Geneva Watch Days launches in upcoming posts. We’ve posted a few teasers below for those who can’t wait until then.

Alongside the many new dome clocks and pocket watches Patek Philippe is debuting during its wide-ranging Rare Handcrafts 2020-2021 exhibition in Geneva this month, the manufacture is also presenting six ongoing-collection wristwatches re-interpreted with new artisanal craftsmanship.
These debuts include a Ref. 6002R-001 Sky Moon Tourbillon, a diamond-set minute repeater with retrograde perpetual calendar (Ref. 5304/301R-001), a minute repeater with perpetual calendar (Ref. 5374-001), the Ref. 7040/250G-001 Minute Repeater for Ladies, a richly decorated Golden Ellipse (Ref. 5738/51G-001), and a white gold Nautilus set with diamonds. Prices for all these models are on request.
The Ref. 6002R-001 Sky Moon Tourbillon Haut Artisanat
Patek Philippe has given this ultra-complex watch (with twelve complications) a stunning hand-engraved rose-gold case with a brown dial in grand feu champlevé and cloisonné enamel.
Patek Philippe’s engravers spent more than 100 hours creating the ‘volutes and arabesques’ case, crown and repeater slide. As Patek Philippe’s second most complicated model, the Sky Moon Tourbillon combines a tourbillon and a minute repeater that strikes on cathedral gongs, a perpetual calendar with a retrograde date, a moon-phase display and the leap year cycle.
From the back, you’ll see a celestial chart showing the apparent motion of the moon and the stars. Patek Philippe will deliver the new Ref. 6002R-001 Sky Moon Tourbillon with hand-engraved cufflinks in rose gold. It replaces the Ref. 6002G-010 in white gold with a black grand feu enamel dial.
The Ref. 5374G-001 Minute Repeaterwith a perpetual calendar
Initially available in platinum, this chiming watch with cathedral gongs now boasts a white-gold case with a glossy blue grand feu enamel dial. Also new are the slightly larger perpetual calendar (day, date, month, leap year cycle) displays, placed on slightly enlarged subsidiary dials. In addition, the white gold hands are now highly luminous, while themoonphase aperture is made using the champlevé enamel technique and then framed in white gold (see below).
Ref. 7040/250G-001 Rare Handcrafts Minute Repeater for ladies
This groundbreaking minute repeater is now extra luxurious with a blue grand feu flinqué enamel dial and a bezel with a Flamme diamond setting. The new model is slightly larger (36m) than the earlier models, and also boasts a diamond-set bezel.
If you recall the dial on the Patek Philippe “Siamese Fighting Fish” pocket watch from 2019, you’ll see a similarity with this new model. Artisans fully guilloche the dial’s gold plate and then coat it with transparent blue enamel that allows the underlying decor to shine through. This method is an old technique called flinqué enameling. Patek Philippe insures that this watch remains thin (5.05mm) by using its self-winding caliber R 27 PS, powered by a 22-karat gold eccentric mini-rotor.
Ref. 5738/51G-001 Golden Ellipse Haut Artisanat
This new design takes full advantage of one of Patek Philippe’s most classic case shapes. Here in white gold, the Ellipse boasts a stunning champlevé enamel dial that has been manually engraved. The watch’s curly-cue decor, known technically as ‘volutes and arabesques,’ nicely complements the oval case shape of the Golden Ellipse.
Inside Patek Philippe places its famed automatic Caliber 240 powered by an off-center recessed mini-rotor in 22-karat gold. The thin (6.58mm) watch joins the current Golden Ellipse collection, which also includes Ref. 5738P-001 in platinum with a blue sunburst dial and the Ref. 5738R-001 in rose gold with an ebony black sunburst dial.
Ref. 7118/1450G Nautilus Haute Joaillerie
Released in rose gold just a few months ago, this newest highly reflective diamond-set Nautilus can now be had in a white gold case. Set with a random pavé setting (also called snow setting), the watch’s case, dial, bezel, and the bracelet are decorated with nearly 13 carats of diamonds. Still, despite the glitter, the blackened white gold hands remain visible thanks in part to a generous coating of luminous material.
This 32.5mm white-gold case is fitted with the automatic Caliber 324 S movement that has been elaborately finished and visible through the sapphire-crystal case back. Sunglasses please.
Ref. 5304/301R-001 Minute Repeater with a retrograde perpetual calendar
Now in a 43mm rose-gold case set with eighty baguette diamonds, this grand complication was first launched in 2006 in a platinum case. Its new diamond frame boasts 6.22 carats of diamonds on its bezel, lugs and clasp, dramatizing Patek Philippe’s seriously complicated system for clearly displaying the day, month, and leap year cycle with transparent sapphire-crystal disks. To add subplots to the drama, Patek Philippe has also added white-gold inlays with engraved leaf motifs in the case flanks and the repeater slide.
The back offers its own window into the architecture of the self-winding caliber R 27 PS QR LU movement, most notably the minute repeater mechanism with two gongs. The viewer can also watch the whirring of the centrifugal governor during chiming. Finally, Patek Philippe artisans re-imagined the finished here with a leaf motif now visible on the rose gold mini-rotor. Patek Philippe has built so many stunning technical and artisanal highlights into this watch, we highly recommend you view the brands’ own visual tour, available here.
Patek Philippe this week launches a platinum-cased Grand Complication, the Ref. 6301P Grande and Petite Sonnerie, Minute Repeater with Jumping Seconds, the Geneva watchmaker’s primary technical watch debut for 2020.
With its black grand feu enamel dial, slanted Breguet numerals and relatively unadorned time and power reserve indications, the new watch understates its impressive and complex chiming mechanism. While eyeing a classically presented time display, a wearer can also place an ear to the 44.8mm case and enjoy a rarely orchestrated symphony of three gongs: a grande sonnerie (full strike), petite sonnerie (small strike) and an on-demand minute repeater.
Patek Philippe has also added an unexpected layer of complexity to the new watch by incorporating a jumping seconds indicator, prominently displayed at the 6 o’clock position on the dial. Patek Philippe looked to its Reference 5275 from 2014 for inspiration on this complication, as that chiming model boasted jumping hours, minutes and seconds.
Patek Philippe watchmakers, well-versed in designing and building the brand’s highly regarded and extensive range of chiming watches, developed the new caliber GS 36-750 PS IRM movement directly inspired by Caliber 300 used in the Patek Philippe Grandmaster Chime Ref. 6300 from 2014.
Unlike most chiming watches from Patek Philippe and elsewhere, the new watch’s chime control center is located below the 6 o’clock position rather than on the left side of the case. On this watch, the selector can be adjusted to petite sonnerie mode (left side), grande sonnerie (center) and silence (right). The user activates the minute repeater on request with the pusher in the winding crown.
Because Patek Philippe opted to place that strike mode selector at 6 o’clock on the case, the watchmaker needed to move its traditional small-diamond platinum case indicator to the side of the case at the 12 o’clock position.
Two series-connected twin mainspring barrels power the new caliber GS 36-750 PS IRM movement. One assures a power reserve of 24 hours for the striking mechanism while the second ensures a 72-hour power reserve for the movement.
All this chiming and timing occurs within a platinum case that may look familiar. Inspired by the Ref. 5370 split-seconds chronograph Patek Philippe presented in 2015, the case features rounded contours, a concave bezel and a slightly cambered sapphire crystal.
In summary, the new Patek Philippe Ref. 6301P Grande Sonnerie includes these six complications:
Movement power-reserve indicator
Strikework power-reserve indicator
In addition, the new watch offers unique technical achievements that have resulted in the Geneva watchmaker earning three patents, which Patek Philippe describes below:
Isolation of the grande sonnerie in the silence mode (Patent CH 704 950 B1). In the silence mode, this mechanism totally isolates the grande sonnerie from the power flow and eliminates energy consumption.
Selection of the strike work mode (Patent CH 706 080 B1). This mechanism enables the selection of the strike work mode (petite sonnerie, grande sonnerie, silence) with a single lever and a single slide switch. Two slide switches were formerly required for this operation.
Jumping display with a jumping seconds wheel (Patent CH 707 181 A2). This innovative mechanism for jumping displays does not require springs and levers but instead uses wheels and a release lever that instantaneously unblocks the wheel train every second, and features a coiled return spring as the only power element. The advantage of this system is that it makes energy consumption easier to regulate and control.
Patek Philippe will offer the new Ref. 6301P Grande Sonnerie on a shiny black, hand-stitched alligator leather strap with square scales, secured with a fold-over clasp. The price for the limited production watch is available upon request.
