The 41.5 mm diameter Constant Force Tourbillon 11 watch in 18-carat yellow gold, released by Arnold & Son as a limited edition of 11, is driven by a hand-wound mechanical movement. Equipped with two barrels to give a 100-hour power reserve, this timepiece was entirely developed and built at the manufacture in La Chaux-de-Fonds. It is fitted with a constant force mechanism visible on the enamel dial and is regulated by a tourbillon that can be seen on the back. The architecture of this calibre is inspired by that of the timekeeping instrument driven by the first tourbillon created by Abraham-Louis Breguet in 1808, based on a chronometer movement designed by John Arnold. This first tourbillon regulator, now in the British Museum, was given to John Roger Arnold by the Paris-based watchmaker in honour of his scientific collaboration and friendship with his father. The Constant Force Tourbillon 11 timepiece, designed to mark the end of the 260th anniversary celebrations of John Arnold’s legacy, pays tribute to the watchmaker’s ingenuity and his close association with Abraham-Louis Breguet.

The greatest watchmakers of the Age of Enlightenment often knew each other. Some of them exchanged views and appreciated each other despite language barriers and political obstacles. And this was the case with John Arnold and Abraham-Louis Breguet. These two watchmakers, undoubtedly the most productive of the second half of the 18th century, forged a friendship that nothing could shake, not even the throes of war between the two countries or the French Revolution. Aware of their respective talents, during Abraham-Louis Breguet’s frequent trips to London between 1789 and 1791, they shared their views and knowledge of the principles of timekeeping, furthering the science of timekeeping, which in their eyes definitely knew no frontiers.

DANIEL ROTH proudly presents the Tourbillon Platinum, a timepiece that pays homage to the brand’s rich heritage and its founder’s enduring passion for the tourbillon complication. This exceptional creation is inspired by the 1988 reference C187 and reinterprets it with modern refinement, artisanal craftsmanship, and a noble platinum case.

The signature double-ellipse case, now crafted in platinum, measures 38.6 x 35.5 mm and is just 9.2 mm thick. It houses a hand-guilloché dial made of solid white gold, finished in anthracite and accented with a sterling silver chapter ring. The dial’s linear guilloché pattern is executed by a single Maître Guillocheur over three days, reflecting the brand’s commitment to traditional métiers d’art.

Inside beats the DR001 calibre, a manually wound movement developed by Michel Navas and Enrico Barbasini at La Fabrique du Temps Louis Vuitton. Comprising 206 components, it offers an 80-hour power reserve and operates at 3Hz. The movement is entirely hand-finished, including hidden components, and features a triple-arm seconds hand—a nod to Daniel Roth’s original design language.

The Tourbillon Platinum is the third model in the brand’s rebirth, following the Tourbillon Souscription and the rose gold edition. It offers a more contemporary aesthetic while remaining faithful to the brand’s DNA of mechanical excellence and elegant restraint.

The Armin Strom One Week Titanium Skeleton, an openworked masterpiece now fully skeletonized to reveal the intricate heart of its mechanics, combines striking design with precision engineering. Encased in lightweight titanium grade 5, it balances strength with comfort, providing a feeling of lightness that makes it easy to wear all week long.

The Armin Strom One Week Titanium Skeleton is a showcase of skeletonization, a technique that is rooted in Mr. Armin Strom’s philosophy and heritage. He sought to enhance depth and three-dimensionality while avoiding see-through to maintain elegance.

The 2023 One Week was already openworked by nature, but this version goes even further, removing more material to highlight the movement’s complexity. Few watches combine openworking and skeletonization at this level. The small seconds dial is skeletonized, revealing the power reserve level and the escapement wheel for a 3D mechanical animation. The mainplate and the barrels are also skeletonized enhancing aesthetics. Thanks to this skeletonization, the power reserve indicator is highlighted as well as the cone mechanism, reminiscent of ancient pocket watches. A major highlight is the case back, offering a mesmerizing view of the entire mechanism.

With a 7-day power reserve, this watch keeps time accurate for an entire week without needing winding. The hand-finished details reflect the level of craftsmanship behind its design. Limited to 100 pieces, the One Week Titanium Skeleton offers a refined, functional timepiece that blends robustness and comfort in a minimalist package.

A harmoniously arranged skeletonised calibre with an evolved and subtle watchmaking style. Arnold & Son has reworked its Nebula collection, giving it a more striking case with a universal diameter of 40 mm while retaining its remarkably finished movement and unique abundance of watchmaking tradition. Two versions – one with a rhodium-plated and black calibre, the other with golden accents – ensure that the Nebula 40 Steel shines bright. The aesthetics of the Nebula collection are unlike any other skeleton: its structure conveys watchmaking spirit, its style expresses unique elegance, and the overall effect is one of outstanding finesse.

The case of the Nebula collection has been redesigned, modernised and refined. With streamlined lugs, a softly rounded bezel, a more vertical case middle and a diameter of 40 mm in harmony with its thickness of just 9.10 mm, this steel case opens a new chapter for the collection. Featuring the A&S5201 skeletonised calibre offering an ultra-graphic layout, Nebula retains its identity as a watch whose movement fascinates, captivates and draws the eye into its depths.
