A timepiece unveiling the aesthetic technique of a finely hand-decorated movement.

JULY 02 2024    |    Novelties

For the final titanium 41mm, three-hands limited edition with rubber strap, Romain Gauthier presents a timepiece with a partially open dial, unveiling a portion of the entirely hand-decorated movement.

C by Romain Gauthier Titanium Editions are modern timepieces with a sporty design that encloses a titanium movement whose hand-finishing prowess can be admired on the case-back. This time Romain wanted the stunning features of this movement to be easily visible just by looking at the watch, even when worn. By opening the dial, he reveals the beauty of the mechanism inside, bringing a technical aesthetic to this timepiece, which until now has featured a full dial.


This partially open dial is particularly reminiscent of the history of the brand's very first timepiece, the Prestige HM, which evolved to reveal the seconds-hand mechanism on its sister caliber, the Prestige HMS.

Unveiled in 2021, the C by Romain Gauthier caliber was the result of more than 16 years of know-how acquired through the brand's development and its manufacture, while reflecting Romain's creative freedom with a modern and youthful design.

Technical in nature, casual in style and free in spirit, the Freedom collection has enabled the creation of this contemporary caliber. The significance of C by Romain Gauthier lies in its creative approach to reinforce the notions of continuity with its concept and design, in reference to the Continuum. Reflecting a vision of the future for a timepiece which is part of Romain Gauthier's philosophy, and which opens the door to new horizons.

During its creation, it was clear to Romain that the case had to harmonize with the movement. It had to be contemporary and uncluttered. But not only that – comfort, ergonomics and the choice of materials also contributed to the design of this timepiece with the decision to use Grade 5 titanium. The dial, in sapphire for this edition, adds to the consistency of the piece and evokes a sense of continuity, as no circle completes the time indication.

Inspired by the finger bridges style, the design of the movement follows the watchmaking history of the Vallée de Joux but with a modern approach, reflecting Romain’s vision of the evolution of tradition.

Romain Gauthier presents the sixth edition of the caliber in titanium in a limited edition of 88-pieces and engraved “1 of 88” on the back of each movement.

 

A partially openwork dial
The C by Romain Gauthier Titanium Edition Six features a sapphire dial that is partially open to the seconds mechanism and escapement.

The seconds wheel is the main feature of this opening. In addition to its mechanical aspect, this wheel is an aesthetic symbol unique to the brand. Its shape and openings are typical of Romain Gauthier wheels - the decorative circling and polished angles attest the care devoted to the finishing of each component.

The partial opening of the dial also reveals the escapement assembly with the escapement wheel, balance and pallet fork. A decorative bridge on the lower part of the dial has been added - thanks to a special hand engraving technique, the specialists at Manufacture have reproduced the boucharder texture found inside the bridges on the movement.

By opening the dial at the front and leaving the movement visible at the back, Romain Gauthier highlights heart of this caliber. Thanks to the decoration of each component, this timepiece takes on a new visual dimension - contrasts and plays of light bring this Grade 5 titanium movement to life.

The dial of the C by Romain Gauthier, a symbol of modernity and continuity both in terms of architecture and design, features off-center hour-minute hands and slightly tapered hour markers of varying lengths. The 5-second intervals of the small seconds at 7 o'clock are also marked by tapering orange lines of differing lengths.

Romain explains this purposeful play on perspective, saying: “Rather than a series of enclosed circles, as we often see in watchmaking, I wanted an open, airy dial on which full or part orthogonal lines form vanishing points with the axes of the hands, reinforcing the notion of continuity.”

The tapering, three-dimensional hands and index are made from 18k white gold and filled with Super-LumiNova for enhanced legibility, as are the numerals and applied hour markers, each of which has been produced from a single piece of white gold and features bevelled edges to give a punchy presence.

 

Eye-catching case and strap high on details
Framing the dial is a titanium bezel whose eye-catching, geometric profile is unlike anything previously seen on a Romain Gauthier timepiece. The bezel is first machined into a round shape featuring a circular bevel before six straight sides are cut into it to create 6 facets. While these facets, which have been polished, reflect the light and bring the bezel to life, the rest of the bezel absorbs light thanks to its satin-finishing. The same facetted design is replicated around the sapphire crystal on the back of the watch.

In between the bezel and caseback, the one-piece caseband and lugs are geometrically sculpted, with satin and polished finishes as well as aesthetic grooves cleverly deployed to draw out the resulting shapes. Meanwhile, the rubber strap with titanium pin buckle follows the form of the angular lugs and rounded caseband so it appears as a continuous, organic extension of the case.

And not for the first time in his work, Romain has placed the crown for winding and time-setting at 2 o’clock, freeing up space for wrist movement. A rubber ring around the crown makes it easier to manipulate, as well as adding a dash of colour to the timepiece.

 

Clever stop-seconds mechanism that uses a snail cam
Romain has endowed C by Romain Gauthier with a stop-seconds – or hacking seconds – mechanism, allowing the wearer to set the time exactly according to a reference time.

Like many stop-seconds mechanisms, a brake is placed on C by Romain Gauthier’s balance wheel when the crown is pulled out. But instead of using a straight or L-shaped balance stop lever to halt the balance, Romain has opted to employ a snail cam that performs a double function: It touches and stops the balance wheel when the crown is pulled out and, when the crown is pushed back in, the snail cam makes a turn, with its increasingly wide form giving the balance an impulse to help it start beating again.

Those familiar with the brand will know Romain has used the snail cam’s unique shape in his past creations: It appears on the watchmaker’s acclaimed Logical One.

 

In-house movement where design and decoration meet modernity
The themes of modernity and continuity carry over to the manual-winding, in-house movement, which is gloriously on show through the display back.

Taking centre stage are a number of finger bridges – historically typical of the Vallée de Joux, Romain’s birthplace – but reinterpreted here in a contemporary way. For starters, these bridges are horizontally configured and feature a ‘stepped’ shape – previously seen on some of Logical One’s bridges – that not only provides volume and depth, but also gives the sense that the bridges are literally flowing over the gears and balance wheel, with no clear end to them.

Like the case components, the bridges are made from lightweight, natural Grade 5 titanium and they boast contrasting tones and textures thanks to a variety of finishes. The outer edges of each bridge all feature a double bevel, while the flat bridge surfaces and rubies are each framed by a raised border that has been straight-grained. Within these borders, the hand- finishing specialists at Manufacture Romain Gauthier have used a special hand-engraving technique to create a highly original dimpled texture. The movement mainplate beneath has been hand-frosted.

The impressive decoration doesn’t stop with the bridges and mainplate: Romain’s trademark gears and ratchet wheel featuring circular, bevelled spokes have been circular-grained, while the click, snail cam and screws with S-slot heads – another signature of Romain – have been highly polished. Finally, the lid of the mainspring barrel has been embellished with a superb snailing decoration.

C by Romain Gauthier’s regulator features the Romain Gauthier balance wheel with curved arms and calibrated eccentric weights, plus hand-assembled pallet lever that is triangular for maximum rigidity.

Chronoswiss presents the ReSec Snake: A Venomous Twist on Modern Mechanical

Known for bold evolutions of mechanical wristwatches and daring designs, Chronoswiss unveils its latest creature: the ReSec Snake. Slithering between heritage and rebellion, this timepiece is a hypnotic blend of color, contrast, and kinetic energy — proof that modern mechanical watchmaking still has a few fangs to bear.

The Snake’s Bite

The ReSec Snake coils into view within a 42mm titanium case, coated with a mesmerizing color-changing PVD-coating that shifts from emerald green to turquoise, depending on the light. It’s not just a case — it’s iridescent armor, capturing the reptilian allure of a serpent in motion. Paired with a contrasting white rubber strap, the Snake wraps around the wrist with smooth, tactile elegance.

But the true venom lies beneath the sapphire crystal. A green CVD-coated dial, hand-guillochéd in the Lucerne Atelier, pulses with depth and hypnotic texture. It’s a dial that doesn’t just tell time — it seduces it.

Take a closer look, and the architecture reveals itself: the iconic 3D regulator layout of the ReSec series slithers across the dial, framed by green hour and minute rings and a retrograde second display, like the flick of a serpent’s tongue. Underneath, the exposed gear train glimmers in contrasting tones — a mechanical exoskeleton that moves with silent precision.

Fangs Beneath the Surface

Powering this cold-blooded beauty is the Chronoswiss Manufacture Caliber C.6005, featuring a 55-hour power reserve, ruthenium-plated finishing, and a radial Côtes de Genève motif. It’s mechanical watchmaking at its sharpest: sleek, silent, and engineered to strike.

Limited. Lethal.

Only 100 pieces of the ReSec Snake will ever exist — a rare breed for collectors with a taste for the untamed. The ReSec Snake is a statement: of daring, of detail, and of defiance — proving once again that at Chronoswiss, we don’t follow rules. We shed them.

Introduction of assertive new black dials for the C by Romain Gauthier Titanium Edition Bracelet

Released initially with a grey dial and then with a Lever de Soleil color dial, the C by Romain Gauthier Titanium Edition Bracelet is now featured with two new dials: a three-dimensional straight grained structured dial in Grade 5 black titanium with white details and a black sapphire openwork dial with blue and white accents.

The three-dimensional straight grained black titanium dial provides an even more assertive character with its textured surfaces. The sharp contrast between the white details and the dark background enhances the time indications. This dial embodies a distinctly modern design while maintaining excellent readability, even in low-light conditions, thanks to the use of Super- LumiNova on the indexes, numerals, and hands.

As for the sapphire openwork dial, it reveals the intricate components of the movement, showcasing the brand's sophisticated watchmaking engineering and artisanal craftsmanship. This openwork design creates a captivating interplay between transparency and structure, transforming the watch into a true technical and aesthetic masterpiece. When Romain launched the first edition of C by Romain Gauthier in 2021, it was clearly stated that this new caliber would lead the brand to new horizons. One year later, a new door has been opened with the arrival of the brand's first metal bracelet.

Sober and contemporary, propitious to variations and adaptations, C by Romain Gauthier was an obvious choice for the creation of a metal bracelet. The desire of modernity, comfort and ergonomic already initiated during the conception of the first edition, reinforced the development of this integral timepiece on a titanium bracelet - light, resistant, modern and sophisticated. Aesthetically, it was important to Romain that the bracelet and the watch become one. As he said: "The bracelet is the case, and the case is the bracelet". This desire is reflected in the fusion of these two elements, a timepiece as a whole that cannot be dissociated.

In keeping with Romain's vision - The Evolution of Tradition - this new technical and contemporary element requires a high level of craftsmanship and hand finishing. Each link is composed of hand-polished and satin-finished surfaces that play with the light and reflect the technical nature of the bracelet and the piece in general.

DANIEL ROTH Unveils the Extra Plat Rose Gold Skeleton

A contemporary expression of classical proportion, revealing the architecture of high watchmaking
 

DANIEL ROTH presents the Extra Plat Rose Gold Skeleton, a new interpretation of one of the Maison’s most emblematic creations. Remaining faithful to the proportions and restrained elegance of the Extra Plat, this latest iteration introduces skeletonisation for the first time in the brand’s modern revival, allowing the inner architecture of the watch to take centre stage.

Conceived in the spirit of La Montre Objet d’Art, the Extra Plat Rose Gold Skeleton preserves the calm geometry of the double‑ellipse case while offering a transparent view into the movement, transforming technical construction into a visual and artistic experience.

The Extra Plat: A signature revisited
Simplicity, when executed with absolute precision, has long been central to the identity of DANIEL ROTH. During the early years of his independent career, Mr. Roth considered the Extra Plat a complication in its own right, favouring it for the technical discipline required to achieve true thinness and perfect proportion.

Defined by its double‑ellipse case and balanced architecture, the Extra Plat became a cornerstone of the Maison’s aesthetic vocabulary in the early 1990s. While Daniel Roth produced skeletonised versions of select complications during that period, the Extra Plat itself was never skeletonised. This new creation therefore marks a respectful yet meaningful evolution, expanding the expressive range of the Extra Plat while remaining faithful to its original spirit.

The DR002SR calibre: a skeletonised rose gold heart
At the centre of the Extra Plat Rose Gold Skeleton is the new manually wound calibre DR002SR, developed and manufactured entirely at La Fabrique du Temps Louis Vuitton under the supervision of master watchmakers Michel Navas and Enrico Barbasini.

Based on the DR002, the DR002SR has been re‑engineered from the ground up specifically for skeletonisation. The bridges and plates have been reshaped to maximise openness and visual clarity, while preserving structural rigidity and chronometric performance. Crafted in solid 18k 5N rose gold, the movement mirrors the warmth of the case and provides an ideal canvas for traditional hand finishing.


Transparency in motion
Skeletonisation is an exercise in reduction and balance. With the DR002SR, DANIEL ROTH brings this principle to its highest expression. The calibre reveals a wealth of hand‑executed details, including numerous hand‑polished internal angles, black‑polished steel components, and meticulously bevelled bridges—finishes that can only be achieved by skilled artisans and never by machine.

Despite its openworked construction, the DR002SR retains a power reserve of 65 hours and a frequency of 4 Hz, underscoring the Maison’s commitment to both technical integrity and timeless aesthetics.


Slim proportions, uncompromised structure
Housed in a 38.6 × 35.5 mm double‑ellipse case crafted in 18k rose gold, the Extra Plat Rose Gold Skeleton measures just 6.9 mm in thickness. This exceptional slenderness ensures that the watch remains true to the Extra Plat philosophy of discreet elegance and effortless wearability.

Produced in extremely limited numbers each year, the Extra Plat Rose Gold Skeleton is intended for collectors who value traditional high watchmaking expressed with clarity, restraint, and depth.

Traditional craftsmanship with modern appeal - Moritz Grossmann TREMBLAGE Green

Moritz Grossmann proudly unveils the TREMBLAGE Green, a limited edition timepiece that redefines elegance through heritage craftsmanship and a bold new aesthetic. Available in rose gold and white gold, with only 8 pieces of each, this extraordinary watch is a tribute to the art of traditional engraving and the timeless beauty of horological design.

At the heart of the TREMBLAGE Green lies a dial crafted from German silver, meticulously hand-engraved using the rare tremblage technique. This centuries-old method creates a fine, matte texture that diffuses light with a soft, meditative glow. The dial is finished in a deep, complex green—symbolizing renewal, harmony, and depth—making it a standout piece that remains understated and refined.

Encased in a 41 mm case of 750/000 rose or white gold, the watch is powered by the in-house calibre 100.1, a hand-wound movement visible through a sapphire crystal case back. Every component is hand-finished, from the Glashütte ribbing and polished bevels to the engraved balance cock. The watch features hours, minutes, and a small seconds display with a stop-second function, all operated via a gold crown and lateral pusher.

Completing the look is a hand-stitched dark brown alligator leather strap, offering both comfort and sophistication. The TREMBLAGE Green is not just a timepiece—it is a celebration of “Schönstes deutsches Handwerk” (the finest German craftsmanship), brought to life with modern sensibility and timeless appeal.

Arnold & Son Unveils Perpetual Moon 41.5 Red Gold “Year of the Horse” – A Tribute to the Fire Horse

Mystical, untamed and dazzling, the Perpetual Moon 41.5 Red Gold “Year of the Horse” follows in the footsteps of Arnold & Son’s Chinese zodiac collections. In the year spanning 2026 and 2027, the Fire Horse will set the astrological tone for connoisseurs of watchmaking and métiers d’art. To celebrate this flamboyant sign, Arnold & Son presents a limited edition of eight pieces, housed in 41.5-mm red gold cases. And while the noble animal is ever alert, it is at night that the full extent of its fiery, mysterious and incandescent nature is revealed.

A horse rears on a hill top – a commanding silhouette carved out against a star-studded sky, surrounded by the sparks of a metaphorical fire. This is Arnold & Son’s interpretation of the Fire Horse, the sign that will succeed the Wood Snake on 17 February 2026. For the sixth consecutive year, Arnold & Son is back in the saddle, drawing on the full breadth of its artistic savoir-faire. Miniature painting, three-dimensional engraving, fine stonework and the refined finishing of an astronomical moon-phase calibre: the Perpetual Moon 41.5 Red Gold “Year of the Horse” tells a tale of excellence, symbolism and vital energy.

An ardent design
Behind the expressive power of the scene, lies all of Arnold & Son’s creativity and mastery. The horse, in 18-carat red gold appliqué, is hand engraved. From hooves to mane, every muscle seems to ripple with energy. The black aventurine sky shimmers like a vast, celestial expanse, where distant stars mingle with mountainous reliefs and shadowy woodland undergrowth.

In the horse’s wake, hand-painted golden dust evokes a trail of sparks that ignite one after the other as the animal passes. These glowing flashes reflect its inner fire and untamed spirit. Touches of red and yellow Super-LumiNova, diffusing the same nocturnal shades, transform the scene as the light dims. Under the radiant mother-of-pearl moon, the horse’s majestic silhouette stands out, while the embers smoulder with new intensity. Not far away, the constellations of Cassiopeia and Ursa Major take shape on the lunar disc, completing this dual-faced, dual-display dial.

A noble pedigree
On the case back, a secondary moon-phase display enables fast, accurate setting of the lunar age. The heart of the Perpetual Moon 41.5 Red Gold “Year of the Horse”, the manual winding A&S1512 calibre, follows the lunar cycle with exceptional precision. While a true lunation lasts 29 days, 12 hours, 44 minutes and 2.8 seconds, Arnold & Son have achieved such precision that it would take 122 years for the display to drift by a single day from the actual lunar cycle, provided the watch is kept fully wound.

As for all Arnold & Son movements, the A&S1512 calibre is developed, manufactured, decorated, assembled, adjusted and cased up at the Chaux-de-Fonds manufacture. Equipped with two barrels and beating at 3 Hz, it gives the Perpetual Moon 41.5 Red Gold “Year of the Horse” a generous power reserve of 90 hours.
