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

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.

  1. 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.
  1. 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.

  1. 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.

  1. 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

New product: TAG Heuer Aquaracer Professional 300

TAG Heuer cheap has added 3 colors to the Aquaracer Professional 300 series, including the return of Night Diver, allowing the wearer to go beyond the edge and explore in depth.

The new launch follows the release of the Torino Diving Professional 300 series in April G Watch and Miracle Geneva, and TAG Heuer has added three new watch families, including the iconic, all black, lume Ming Dial Diving Professional 300 Night The new iteration of divers.

Our initial reaction to the new version was very positive, especially the Night Diver model, whose all-luminous dial looks white during the day, but is completely illuminated in the dark. The usual qualities associated with TAG Heuer watches, especially the Aquaracer series, have always existed. This is a good thing, because the manufacturing quality is very good, and the watch is sturdy and durable, equivalent to any task at hand, such as a dive watch or a tool watch. The construction is always in place and executed very well. We also like to use two different luminous colors to distinguish the touch of the hour and minute hands-making it easier to identify, especially when the watch can be taken to dark, gloomy depths, given its 300m waterproof rating. The black DLC coated case is very stylish and adds personality to Night Diver.

TAG Heuer fans will recognize the name “Night Diver”, which was first introduced in the mid-1980s. Loved by active and fashion-conscious watch buyers, they continue to push their limits, explore nature, and transcend the edge to become one of the most famous sports watches of the time.

Today’s Aquaracer Professional 300 series tells this story. TAG Heuer’s design, engineering and heritage teams have worked together to faithfully update this beloved watch, retaining and improving iconic details, such as the famous 12-sided bezel and the horizontal engraved lines of the dial to create A sophisticated and versatile modern classic.

Launched three new Aquaracer Professional 300 models
Today’s Aquaracer Professional 300 drop adds three more models to the eight models announced in April, bringing the series to 11 models. All three new models are sold in unlimited quantities and enter the core series, each equipped with a 43 mm stainless steel case and rubber strap, equipped with TAG Heuer (TAG Heuer) innovative adjustable folding clasp.

The new black and blue versions continue the bracelet models launched on Watches and Wonders: both are color-themed, with black or blue dials, ceramic bezel inserts and rubber straps.

The outstanding model of this version is the black DLC-coated Night Diver, adding Aquaracer Professional 300 Tribute to Ref. 844 as the hero of the series. Its stainless steel case, bezel, crown, back cover and buckle are all coated with a matt black diamond-like carbon coating called DLC, a high-performance, wear-resistant coating designed for use in extreme conditions And design. The bezel insert is highly durable black ceramic.

Another iconic feature of Night Diver is its all-luminous dial, which is coated with a green Super-LumiNova® luminous coating to provide excellent luminous performance. To ensure that it remains clear and legible even in very low light conditions, the minute hand and central seconds hand of the watch are painted with blue luminous, which contrasts sharply with the green of the dial. The hour hand and the octagonal hour markers at 12 o’clock, 3 o’clock, 6 o’clock and 9 o’clock are filled with green luminous, and the remaining octagonal hour markers are decorated with black lacquer edges. The triangle on the unidirectional rotating bezel at 12 o’clock is essential for accurate and safe measurement of diving time. It is also full of eye-catching blue luminous light that matches the blue of the minute hand and central second hand. fake watches form china

The details don’t stop there. Like the eight watches in the release series, the three new watches use the six iconic features that have defined TAG Heuer diving watches since 1983: unidirectional rotating bezel, screw-in crown, and water resistance at least It is 200 meters, luminous marking, scratch-resistant crystal and double safety clasp. These real-world functions have become the backbone of the model’s design, and have been reassuring underwater explorers for the past four years.

The form has many further details to enhance its luxury and performance. The 12 sides of the bezel are all faceted for easy grasping, the crown is protected to prevent accidental damage, and there is a magnifying glass above the date, which is integrated under the sapphire crystal mirror, which is smooth to the touch.

All of this is based on the iconic horizontal engraved lines of the Aquaracer dial. These have also been improved for the new generation of watches. Compared with the previous iteration of Aquaracer, they are now slightly farther apart, giving the watch an elegant and refined appearance.

Like the release series, the three new Aquaracer Professional 300 models all use the TAG Heuer Calibre 5 automatic movement. They all have a sturdy bottom cover with the famous scaphander wetsuit printed on it and equipped with 12-sided panels. All Aquaracer Professional 300 models are water resistant up to 300 meters (30 bar, 1,000 feet).

Each new Aquaracer Professional 300 model is equipped with a beautifully designed integrated rubber strap, equipped with TAG Heuer’s newly developed adjustable buckle system.

The fine-tuning system developed by TAG Heuer engineers means that this adjustment can be made to extremely small tolerances. This is done by pinching and sliding the button on the side of the clasp. The clasp also has double safety buttons to prevent accidental unlocking.

These straps will be tailored at TAG Heuer boutiques or authorized dealers as part of the assembly process. Then, the wearer can freely adjust the strap to adapt to the wetsuit, or just reflect changes in environmental conditions, thereby causing the wrist to expand or contract.
