What are the differences between the power system of the Jacob & Co.

Astronomia Four-Axis Tourbillon and its counterpart, the Three-Axis Tourbillon (Astronomia Revolution)? Below, we’ll clarify the differences in the power systems of the Three-Axis Tourbillon (Astronomia Revolution, or simply “Three-Axis”) and the Four-Axis Tourbillon (or simply “Four-Axis”), focusing on five key aspects: movement, mainspring, constant force, rotating platform, and winding method.

Movement Model and Basic Structure

Three-Axis (Revolution): Movement JCAM48B, 434 parts, Jacob & Co.

Structure: Three-axis tourbillon (double-axis tourbillon + platform revolution as the third axis).

Four-Axis (Four-Axis): Movement JCAM54, 485 parts.

Structure: True four-axis (three-axis tourbillon + independent fourth-axis rotating support).

Platform reduced from three arms to two arms, reducing weight and energy consumption, maintaining a 36-hour power reserve. 2. Mainspring and Power Reserve

Similarities: Manual winding, single mainspring barrel, 36-hour power reserve, 21,600 vph.

Differences mainly lie in load and torque management:

Three-axis: Drives three axes + three-arm platform, moderate energy consumption.
Four-axis: Drives four axes + two-arm high-speed platform (60 seconds/revolution), higher speed, greater instantaneous load, stronger mainspring output torque, requiring more precise constant force control.

Constant Force Device (Core Difference)

Both use 1/6-second high-frequency constant force (synchronized with the balance wheel frequency), but the design and load differ:
Three-axis (JCAM48B)
Patented “whip torque adjustment”: Releases energy every 1/6 second, buffering mainspring ripple.
Function: Protects the dual-axis tourbillon escapement, adapts to three-axis speeds (60 seconds, 15 seconds, 60 seconds). fake watch for sale

Quad-axis (JCAM54)

Next-generation high-frequency constant force: Integrated within the tourbillon frame, allowing for greater load capacity and faster response.

Suitable for quad-axis top speeds: 60 seconds, 18 seconds, 15 seconds, and 60 seconds, with the 15-second axis being Astronomia’s current highest speed, doubling the requirements for constant force stability (Jacob & Co.).

Officially described as the “fastest constant force mechanism in history,” it precisely charges and discharges every 1/6 second, offsetting the significant torque fluctuations caused by the high speed of quad-axis operation.

Rotation Platform and Power Distribution

Tri-axis: Three-arm platform, 60 seconds/revolution; tourbillon at one end, the other end containing a timer, jewel, globe, and other counterweights.

Quad-axis: Two-arm platform, 60 seconds/revolution; retains only the tourbillon and timer, eliminating the jewel/globe, reducing weight by approximately 30%, lowering power consumption, and preventing sudden power drops at high quad-axis speeds.

Winding and Time Setting Mechanism

Three-axis: Traditional crown winding + time setting (side of the case).

Four-axis: No crown; replaced by two 18K rose gold bow-shaped winding mechanisms on the case back, 180° rotating operation, suitable for a fully skeletonized design without a side crown, while also optimizing the power transmission path. best copy watch

Differences Overview (Table)

Table | Item | Three-Axis (Astronomia Revolution) | Four-Axis (Four-Axis Tourbillon)

Movement | JCAM48B (434 pieces) | JCAM54 (485 pieces)

Tourbillon | Three-Axis (Dual-Axis + Platform Revolution) | Four-Axis (Three-Axis + Independent Fourth Axis)

Platform | Three arms, 60 seconds/revolution | Two arms (weight reduction), 60 seconds/revolution

Constant Force | Whip-shaped torque adjustment | New generation high-frequency constant force (faster, stronger)

Speed | 60s, 15s, 60s | 60s, 18s, 15s, 60s (higher speed)

Winding | Side crown | Double bow-shaped winding mechanism on case back

Core Objectives | High-speed three-axis | Four-Axis + Ultimate high-speed stability

In short: The four-axis is a “power-enhanced + architecture-upgraded version” of the three-axis – using the new JCAM54 The movement, weight-reducing platforms on both arms, stronger high-frequency constant force, and crownless winding support the fourth axis and higher speeds, while maintaining a constant 36-hour power reserve. luxury moon watch

Watches & Wonders 2026: Hublot Big Bang Reloaded: Usain Bolt and Kylian Mbappé Limited Editions

Watches & Wonders 2026: Hublot Big Bang Reloaded: Usain Bolt and Kylian Mbappé Limited Editions

At Watches & Wonders 2026, Hublot will unveil two limited-edition timepieces dedicated to Usain Bolt and Kylian Mbappé, respectively. While both watches are built on the same technical platform, their design philosophies are strikingly different.

When Hublot collaborates with its brand ambassadors to develop a watch, the final product is far more than just a special edition stamped with a celebrity’s signature. Hublot doesn’t simply print the celebrity’s name on the dial; instead, it draws inspiration from the athlete’s past experiences, incorporating these elements into the materials, colors, and details. This is evident in the two new limited-edition watches. At first glance, the two watches share the same technical foundation, but their messages are entirely different: the Big Bang Reloaded Usain Bolt and the Big Bang Reloaded Kylian Mbappé, respectively. In terms of complications, both special edition watches are flyback chronographs, powered by Hublot’s renowned in-house Unico movement, with each limited to 200 pieces.

A touch of Jamaican flair, a hint of legend, and a dash of Bolt’s humor—this is precisely why these two watches deserve our close examination. Hublot tells two distinct stories on the same platform: on one hand, it emphasizes themes of tradition, heritage, and record; on the other, it highlights confidence, ambition, and the present.

This Big Bang Reloaded Usain Bolt watch is entirely tailored to the symbolic significance of the world’s fastest man: the 44mm case is crafted from black ceramic and carbon fiber, accented with gold details, while green and yellow trim subtly echoes the colors of the Jamaican flag. When Hublot takes personalization to the extreme, the allure of the Big Bang Reloaded becomes even more pronounced: if you imagine the watch spinning, the numbers between 6 and 8 o’clock form “958”—the exact number from Usain Bolt’s 200-meter world record of 9.58 seconds. Echoing this theme, the chronograph hands are designed in the shape of lightning bolts, and the case back even incorporates the original soil from Bolt’s training ground in Jamaica. Furthermore, his motto, “Anything is possible, don’t limit yourself,” is engraved on the bezel. fashion replica watch

The Big Bang Reloaded watch doesn’t take a neutral stance; it clearly expresses its own perspective. Hublot incorporates Bolt’s career, background, and public image into the design, striving for a powerful impact. This watch boasts a bold design, meticulous attention to detail from start to finish. The Bolt special edition watch stands out with its striking symbols, strong contrasts, and design that clearly conveys its message. Even the two interchangeable straps—one a gold Velcro strap, the other a black, yellow, and green camouflage rubber strap—reflect this distinct philosophy.

It’s not a defensive watch, not even in its design.

The Big Bang Reloaded Kylian Mbappé watch presents a completely different design concept. It also boasts a 44mm diameter, but the choice of materials—polished white ceramic and 18K King Gold—creates a completely different impression: the watch appears brighter, more striking, and more modern. If the Bolt watch tells a story of heritage and record, the Mbappé watch emphasizes the spiritual aspect. Therefore, the bezel is engraved with “Trust Yourself” at 6 o’clock—a motto Hublot considers central to its sporting and public image. Furthermore, the bezel is adorned with the gold number 10, representing both Mbappé’s jersey number and his identity and lucky number. The skeletonized dial, crafted from charcoal gray ruthenium metal and accented with white, gives the watch a clean and technologically advanced look. The most significant difference between the two watches lies here. The Bolt Edition draws inspiration from history, symbolism, and a tribute to an established career. The Mbappé Edition, on the other hand, emphasizes presence, speed, and a distinctly forward-thinking image. Like the Bolt Edition, interchangeable straps are part of the Mbappé Edition’s design philosophy: a gold Velcro strap and a black and white rubber strap bearing the KM logo consistently convey the idea of self-realization, with the Mbappé serving as a role model.

However, technically, the two watches share the same fundamental structure. Both are powered by Hublot’s in-house HUB1280 Unico automatic movement, featuring a flyback chronograph function, a clearly visible gear train, and a 72-hour power reserve. Hublot places particular emphasis on showcasing the intricate structure of the Unico movement and the visibility of key components such as the gear train, clutch, and flyback chronograph. This is crucial because, even with the incorporation of various symbolic meanings and personal metaphors, these elements are precisely what give both watches their essential horological significance. This demonstrates once again that the Big Bang series serves as Hublot’s platform for creating groundbreaking works—and that technology itself is by no means insignificant. https://www.whereguidewatch.com

Jacob & Co.’s most dazzling timepieces

Jacob Arabo’s namesake brand is forging a clear path to horological legitimacy. men watches brands

I’ve been racking my brains trying to put into words the influence of Jacob & Co. on the world of haute horology. Because there really is no one like Jacob Arabo in this industry. Arabo came to New York from Russia when he was 14. He started helping support his family at the age of 16 as an apprentice jeweler. While making jewelry for other brands, he sold his creations as a side business before hanging out his own tiles in York 1986 in New York.

His designs soon caught the attention of singer Faith Evans, who turned her husband, Notorious BIG, to Arabo’s work. Soon, he became the immortal “Jacobs the Jeweler” in hip-hop lyrics. But it’s not just celebrities that Jacob & Co. attracts – collectors are also taking notice of his luxury timepieces, as Arabo focuses on highly complex timepieces that are iconoclastic in precious materials such as rare gems design.

A self-made man, Arabo treats watchmaking in the same way that he chooses the best gemstones: technical sophistication, with a certain respect for decadence. Some might say that’s overkill, but at the same time, there’s something dizzying about Jacob & Co.’s work. The following five timepieces perfectly illustrate this iconoclastic watchmaking industry.

Jacob & Co 3-D Astronomical Minute Repeater
Truly an otherworldly watch. 3-D astronomy was first introduced at Baselworld in 2014, and it gets more exciting and sophisticated every year. This year, Jacob & Co. launched the Minute Repeater version just to up the ante on this ultra-rare watch.

It features a carillon repeater with three gongs and hammers (instead of the usual two). The gongs are stacked vertically so you can better see their action through the side of the sapphire case. The chime chimes with the familiar Doh Re Mi tones to mark hours, minutes and 15-minute intervals. An innovative safety feature protects the mechanism by preventing the wearer from winding the watch while the watch is beeping. Four arms radiating from the center support a three-axis tourbillon.

On the icy side, the 3-D Astronomia is set with a 15.44-carat sapphire in two shades of blue, with baguette diamonds on the baseplate and case. The display also shows a 1-carat spherical diamond and a lacquered dial spinning globe. The coolest part? Flying astronauts revolving around the axis of the 3D Earth!

Jacob & Co. Twin Turbo Furious: Twin Turbo Furious Bugatti Edition
In an equally disruptive business move with Jacob & Co.’s luxury timepieces, the manufacturer announced in March a long-term partnership with automaker Bugatti on a range of exclusive co-branded products. According to the press release, the partnership hopes to push “the limits of what is mechanically possible.”

The news marks the end of Bugatti’s long-standing relationship with Parmigiani Fleurier, who also produced some great timepieces. But with Twin Turbo Furious: Twin Turbo Furious Bugatti Edition, Jacob & Co. is once again looking to up the ante on technology. The watch is driven by two three-axis tourbillons (to ensure precise timekeeping). Other extras under the hood include a column-wheel chronograph and a decimal minute repeater that sounds at 10-minute intervals.

The appearance is also a bit flashy. Its turquoise blue bezel is a tribute to Bugatti’s 110th anniversary blue Chiron. It also features the Bugatti logo in the center of the dial between the chronograph counters. The power reserve indicator at 6 o’clock is called the “fuel” indicator.

Jacob & Co. Bugatti Chronograph Limited Edition 100 Years
The second piece from the Jacob & Co./Bugatti collaboration, the Chrono Edition Limitée 100 Years, is less exclusive. In homage to Ettore Bugatti’s 100th anniversary in 1909, only 110 will be produced.

Also inspired by Jacob & Co.’s original Epic X Chrono, this watch features a column-wheel movement. This version is made of forged carbon, with a matte black dial and the colors of the French flag running vertically between the subdials. It comes with a rubber strap that also pays homage to the Chiron. Because it’s not diamond-encrusted, its price (for the brand) is a respectable CHF 36,000, and it could even be considered an entry-level Jacob & Co.

Jacob & Co. and Messi: Epic X Chrono Messi
2019 was a big year for Jacob & Co. In January, the brand signed a deal with football legend Lionel Messi – nine-time champion of the Spanish Football League, four-time Champions League winner, five-time – best player in the world Ballon d’Or winner, five-time winner of the Golden Boot for the top scorer in Europe, and Olympic gold medalist.

In recognition of Messi’s outstanding achievements, Jacob & Co has teamed up with the football god to create a series of equally legendary timepieces. The Epic x Chrono “Messi” model features 47mm polished grade 5 titanium, titanium and rose gold or titanium and white gold, diamond-set case, anti-reflective sapphire glass, ceramic chronograph bezel and pushers, and rubber lugs, and crown.

The light blue and white colour scheme draws on Messi’s Argentine heritage. The timepiece also features his famous red No. 10 on the flange ring, the “Messi M” logo at six o’clock on the dial, and the signature on the glass sapphire caseback, while also displaying the automatic dual composite skeleton chronograph Watch movement.

Jacob & Co. Billionaires
If I first heard about the jeweler Jacob through Jay-Z’s “Money Ain’t a Thing,” it wasn’t until Baselworld 2015 that I was truly blown away by the billionaire.

This is unique, created by Arabo in association with Flavio Briatore and his Billionaire Lifestyle SARL company. Media at the time described it as “a dazzling representation of the brave and rebellious Jacob & Co. spirit”.

This handcrafted and exclusive Jacob & Co. Skeleton manual winding tourbillon movement JCAM09 is enough to take your breath away. But the real glory is the 18K white gold 58 X 47.5mm case and bracelet set with 260 carats of emerald-cut diamonds. Every stone is important, and some of them individually weigh up to 3 carats. They are all individual beads to maximize brilliance.
