New launch: Ulysse Nardin Diver [Air] is the world’s lightest mechanical diver’s watch

Ulysse Nardin Diver [Air] (reference 3743-170-2A/0A)

As the flagship for Watches & Wonders Geneva 2025, Ulysse Nardin has just unveiled the world’s lightest mechanical diver’s watch. Made from high-tech recycled materials, the new Ulysse Nardin Diver [Air] is driven by a highly skeletonized automatic movement, with bridges machined from titanium and, like the rest of the collection, water-resistant to 200 meters; however, the entire watch (including the strap) weighs just 52 grams, less than half the weight of the brand’s standard Diver X Skeleton model.

Despite sharing the same overall silhouette as the brand’s standard diver’s models, the new Ulysse Nardin Diver [Air] measures 44mm in diameter and 14.7mm thick, making it one millimeter thinner than its Diver X Skeleton sibling. As you’d expect, the top of the case features a domed sapphire crystal surrounded by a unidirectional rotating chronograph bezel, while the back of the watch features a screw-down exhibition caseback with a signature winding crown at 3 o’clock that screws into the middle case to ensure the 200 meters of water resistance this model offers. With this in mind, and in order to significantly reduce the weight of the new Diver [Air], Ulysse Nardin had to resort to materials different from those typically used in its dive watch manufacturing.

The Diver [Air]’s case is made from titanium and carbon fiber, but rather than working with traditional suppliers, Ulysse Nardin replica worked with forward-thinking innovators in the field of high-tech materials to source these materials. Titanium is used for the internal container that houses the movement, as well as the watch’s bezel, crown, and caseback. The titanium used in the Diver [Air] is 90% made from recycled materials and is manufactured by TiFast, a leading titanium producer, and ThyssenKrupp, a specialist in materials and engineering solutions focused on automotive technology and marine systems. TiFast recycles titanium from the Swiss biomedical industry, which is then processed by ThyssenKrupp using its various technologies and heat treatment methods to further enhance the alloy’s processing and deformation properties.

The rest of the case is made from Nylo®-Foil, a carbon composite material that is lighter than traditional carbon fiber. Nylo®-Foil is composed of 60% Nylo® (a polymer made from recycled fishing nets by French recycling startup Fil & Fab) and 40% carbon fiber, which comes from the IMOCA sailboat manufactured by CDK Technologies. The carbon fiber is recycled and returned to its original fiber state by Extracthive, a company committed to the circular economy, and then Lavoisier Composites processes the Nylo® and carbon fiber to create the Nylo®-Foil material. Meanwhile, the bezel insert of the Ulysse Nardin Diver [Air] is made of CarbonFoil, which is made from 100% recycled carbon fiber from IMOCA sailboats that are chopped and compressed into a sturdy structure with a unique marble-like forged carbon pattern.

Rather than a heavy rubber strap like most brands’ dive watches, the new Ulysse Nardin Diver [Air] comes with two ultra-light elastic fabric straps. The two straps are bright orange or white, but other than the color difference, the two straps are identical, both with a wraparound design and a Velcro-style connection system. Since the straps are connected to the case via Velcro, the two included straps can be easily replaced without the use of any tools, and the Velcro-style closure also provides users with a nearly infinite range of adjustability. Additionally, since the strap is essentially just a piece of stretchy fabric with a black plastic pull tab, it only adds a few grams of weight, and the Diver [Air] weighs 46 grams for the watch head, and only 52 grams with one of the included straps. wholesale replica watch

Creating a lightweight case and strap certainly helped keep the watch’s weight down, but to create a watch that’s close to breaking the record, the movement inside also needed to be redesigned. The Caliber UN-374 automatic movement, visible through two sapphire crystals on either side of the Ulysse Nardin Diver [Air] case, is highly skeletonized, with bridges and mainplates made from 90 percent recycled titanium to further reduce weight. The skeletonized titanium bridges have been redesigned to form a triangle for maximum strength, the skeletonized mainspring barrel has been changed to a flying configuration, and by eliminating the upper barrel bridge, Ulysse Nardin was able to further reduce the weight of the movement.

The Cal. UN-374 movement consists of 199 individual parts, is set with 21 jewels, beats at 21,600 vph (3 Hz), and has a power reserve of 90 hours. Similar to other in-house movements of Ulysse Nardin, the Cal. UN-374 is equipped with an oversized balance wheel, whose hairspring and anchor-shaped escape wheel are made of silicon. The 90% recycled titanium used for the plates and bridges is produced by TiFast and Thyssenkrupp, and the silicon used in the regulating organ comes from recycled silicon wafers provided by Sigatec. At the same time, the rotor of the Cal. UN-374 has been hollowed out to the essential elements, and the use of large areas of hollowing out and lightweight materials makes the movement weigh only 7 grams, but it can withstand shocks of more than 5,000g.

Dive watches and skeleton watches usually exist at opposite ends of the horological spectrum, and it is undeniable that the highly hollowed-out display is completely opposite to the legibility that dive watches usually have. That being said, ultra-lightweight skeletonized sports watches have become a very popular horological style, and these haute horlogerie creations are not intended to be purely utilitarian products, but rather to be technical showcases that demonstrate the manufacturing prowess of their respective brands. The Ulysse Nardin Diver [Air] aims not to be the world’s most powerful dive watch, but to be the world’s lightest dive watch, and its appearance is designed to reflect this extreme, with approximately 80% of the space within the case being completely occupied by air.

The Ulysse Nardin Diver [Air] pushes the boundaries of one metric without compromising the others, and although the new Diver [Air] weighs less than half of the brand’s standard Diver X Skeleton model, it still offers a proper automatic movemen. buy replica watches

Corum Golden Bridge

zelin0802

Corum replica has been a highly regarded avant-garde watchmaker since the 1950s. Their design choices draw inspiration from fashion, art and architecture. Respected for their ability to master women’s and men’s watch design. The risk they take with the case sets them apart. Since its inception, Corum watchmaking has been ahead of its time.

The Corum Golden Bridge watch dates back to 1980 when it was first introduced. This model is considered a unique creation of fine watchmaking, with its original design featuring a linear movement and most of the dials. Corum made a bold choice to design the first fully transparent watch. This skeleton watch showcases the watchmaker’s masterpiece and its mechanical beauty. Vincent Calabrese used his talent to create movements with linear gear trains, mounted on a transparent exterior and isolated in space, with no visible connections.

The Golden Bridge is poised, technical, and an icon in its own right. The 113.160.55/002 0000 model has a skeletonized dial; the signature tonneau-shaped rose gold case and a contrasting brown alligator strap. Equipped with an automatic winding mechanism, this timepiece is calibre CO 113 with a 40-hour power reserve when fully wound. The watch is water-resistant to 30 meters and has a watch-like transparency.

Corum Golden Bridge The Corum Golden Bridge uses four sapphire crystals, framed above, below and on the sides by four slender gold ribs, almost like a crystal window that opens the time. The sapphire crystal caseback of the Corum Golden Bridge is secured by four golden screws, ensuring the watch is perfectly water-resistant to a depth of three atmospheres. The latest technological discoveries are used in the production of the replica Corum Golden Bridge watch. The winding and time-setting crown at 6 o’clock, engraved with the CORUM key, extends straight down from the movement and activates the “sliding spring” winding system that avoids stress on the delicate mechanism. The Corum Golden Bridge movement is fully wound and has a power reserve of 40 hours.

Richard Mille RM 88 Automatic Tourbillon Smiley

zelin0802

A yellow circle, two oval eyes, a large upturned mouth… The smiling face drawn by Franklin Loufrani more than 50 years ago has become an established symbol in the collective consciousness. It is the embodiment of positivity, joy and sharing, and has played a major role at the heart of pop culture for generations of creatives. This leadership role was enough for Richard Mille’s team to start creating an emotion-driven copy watch that emphasized all of these values.

mechanism of smile

Around the radiant face of the smiling face, a series of miniature sculptures occupy the movement of the RM 88 Automatic Tourbillon Smiley, forming and transforming a surreal scene full of fun and enthusiasm, demonstrating a true mastery of the infinitely small. As light as it may seem, the creation of this ballet was a technical challenge of the highest order. But the dream is now a reality, with extreme attention to detail and perfection that breathes life into the veritable smile mechanism.

Bottom plate and bridges are made of grade 5 titanium
Micro-sprayed grade 5 titanium with PVD treatment provides great rigidity to the baseplate and bridges, as well as the precise surface flatness that is essential for the perfect operation of the gear train.

Grade 5 titanium is a biocompatible, highly corrosion resistant and very hard alloy that enables the gear train to operate with ease. Richard Mille RM 88 Automatic Tourbillon Smiley

The alloy is 90% grade 5 titanium, 6% aluminum and 4% vanadium. This combination further enhances the mechanical properties of the material, which explains its frequent use in the aerospace, aviation and automotive industries.

The skeletonized baseplates and bridges undergo intensive and complete verification testing to optimize their resistance capabilities.

On top of the Microblasted ARCAP® Additional Motion Work Bridge, a striking gold smiley figure, microblasted and painted, dominates the landscape, complete with polished corners and brushed edges. Featuring a larger iridescent pattern, hand-applied varnished to contrast with anthracite-coloured rhodium-plated, shimmering subtle reflections.

No effort has been spared in finishing, down to the tiniest detail of every element in this display. The cocktail glass consists of four parts, all of which are golden. Umbrellas, olive trees (1.7mm high), fluted straw 0.4mm in diameter – all polished – and the glass itself, whose bottom is micro-blasted to convey its coldness, weighs just 0.4g in total. The gold flowers on it are mirror-polished, and the petals are brushed and rhodium-plated. This pink flamingo, 0.2 gram red gold, has also undergone multiple processes: its wings are polished and its feathers are depicted with the tips of a degussi millstone; its eyes are made with the smallest beading tool in existence ; its base is micro-blasted and the parts depicting grass and water are polished. The component was given a metallic pink PVD coating before the beak was painted black using a brush.

The pursuit of perfection is always there, green PVD ​​coated leaves, pineapple micro-blasted and polished surface, gold cactus micro-blasted, one-by-one polishing to remove PVD ​​​​coating, and sun, micro-blasted gold, polished rays . In keeping with watchmaking tradition, all finishing operations on the RM 88 Smiley are done by hand.

This type of balance wheel represents the pinnacle of innovation. It ensures greater reliability against shocks and during movement assembly or disassembly, resulting in better timekeeping results over time.

Adjuster indices are eliminated and more accurate and repeatable calibration is possible thanks to 4 small adjustable weights located directly on the balance.

ATZ white gold ceramic and red gold case

Such brilliant colors and sets, front and back, deserve an environment that does justice to the composition.

The design and execution of the watch demonstrates a holistic approach to the movement and case concept. Therefore, everything is built to extremely strict specifications. For example, casing rings are no longer used, and the movement is mounted on chassis-mounted rubber (ISO SW) secured by titanium screws.

The bezel and caseback are made of ATZ white ceramic. This is made from a tube of aluminium oxide powder injected under a pressure of nearly 2,000 bar. This high-pressure injection increases stiffness by 20 to 30 percent and minimizes material porosity. ATZ is known for its high scratch resistance (1,400 Vickers) and unchanging color. Second only to diamond, it is one of the hardest materials in the world. Long and difficult machining with diamond tools was required to create this perfect example of the intricately curved bezel and satin finish. Richard Mille RM 88

The strap is made of 18K 5N red gold.

The tripod case is water-resistant to 50 meters, secured by 2 nitrile O-rings. The case is assembled with 12 grade 5 titanium spline screws and 316 L stainless steel wear washers.
