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.

Armin Strom Unveils Mirrored Force Resonance Zeitgeist 1665 – A Tribute to Horological History

Armin Strom unveils the Mirrored Force Resonance Zeitgeist 1665, a creative interpretation of what a Resonance wristwatch might have looked like centuries ago.

Limited to just 25 pieces worldwide, this exceptional creation pays tribute to the centuries-long pursuit of chronometric consistency, a challenge first explored by Christiaan Huygens in 1665. Armin Strom solved the Resonance Fragility Problem in 2016, making this phenomenon practical for wristwatches.

Angelus Unveils Flying Tourbillon Skeleton Titanium in Vivid Orange

Angelus unveils the Flying Tourbillon Skeleton Titanium, Orange Edition, a vivid expression of horological energy and design. Limited to just 25 pieces, this timepiece transforms skeletonised mechanics into a canvas of colour and contrast. The satin-finished titanium case frames a deep black movement, animated by bright orange accents that highlight the time display and extend to three interchangeable straps. The openwork calibre, designed as a series of interlocking circles, adds architectural depth and visual dynamism.

Every detail of this 42.5 mm watch reflects a unique energy. Chromatic energy flows through the orange highlights. Customisable energy is offered by the quick-release strap system, allowing seamless transitions between black alligator leather, orange rubber, and integrated titanium. Light energy emerges from the skeletonised movement, while structural energy is revealed in the layered construction. Graphic energy is embodied in the three-dimensional architecture of the A-310 calibre.

The dial features a floating orange minute track above a black flange, with hour markers crafted for the first time by Angelus in monolithic blocks of Super-LumiNova. These luminous elements ensure legibility in low light and reinforce the watch’s modern aesthetic. At the heart of the case lies a carbon composite chamber, lightweight yet rigid, surrounded by a modular titanium cage that enhances stability and mechanical appeal.

The A-310 calibre showcases Angelus’s signature three-spoke wheels, leading the eye to the flying tourbillon suspended without an upper bridge. Supported by a 160° angled bridge, this asymmetrical design intensifies visual tension and balance. The tourbillon completes a rotation every minute, oscillates at 4 Hz, and offers a 60-hour power reserve. The Flying Tourbillon Skeleton Titanium, Orange Edition embodies the Angelus L.A.B. philosophy—Legacy and Beyond—where technical mastery meets bold design to elevate mechanics into contemporary art.
