With the Waltz N°1 Hoffmann Edition, Carl Suchy & Söhne opens a new chapter within its collection. For the first time, the constructive thinking of Josef Hoffmann is not merely referenced, but systematically translated into mechanics.
The Hoffmann is powered by an adapted ultra thin Calibre CSS-A1 measuring 30 millimetres in diameter and only 2.6 millimetres in height, realised in collaboration with Vaucher Fleurier Manufacture exclusively for Carl Suchy & Söhne. What appears on the dial as disciplined geometry continues within the movement as precise construction.
The world premiere will take place on 13 April 2026 as part of the curated exhibition “Independents’ Salon” at the Hotel Beau Rivage in Geneva. The presentation positions itself as an independent cultural contribution during Watches and Wonders in Geneva.
JOSEF HOFFMANN AND VIENNESE MODERNISM AS A CONSTRUCTIVE PRINCIPLE
The Hoffmann does not follow a decorative motif. Its dial is based on a geometric grid of concentric lines. The numerals 12, 3, 6 and 9 are not applied elements but integral components of this structure, emerging directly from the system itself.
The rotating Waltzing Disc at six o’clock completes the linear composition once every minute. Movement becomes part of order. Time appears as a constructive process.
Slender black hands integrate seamlessly into the composition without disrupting its graphic clarity. The geometric structure of the dial also determines the architecture within. The movement mirrors the dial. Construction becomes a continuous principle.
MECHANICS AS ARCHITECTURE
The adapted ultra thin Calibre CSS-A1, measuring 30 millimetres in diameter and only 2.6 millimetres in height, is fully visible through the sapphire case back. Geometrically skeletonised bridges structure the mechanics with clarity and extend the formal principle of the dial into the movement.
Regulation is ensured by a variable inertia balance fitted with gold weights, oscillating at a frequency of 3 Hertz, or 21,600 vibrations per hour, guaranteeing precise adjustment. Winding is achieved via a gold plated decentralised micro rotor integrated into the ultra thin movement architecture and running on ceramic ball bearings.
The finishing reflects the same constructive consistency down to the smallest detail. Perlage on both sides of the mainplate, rhodium plated surfaces, hand bevelled edges, diamond polished countersinks, as well as anthracite NAC coated and geometrically skeletonised bridges emphasise the architectural clarity of the construction.
The Hoffmann is handcrafted in Switzerland in precise artisanal execution by master watchmaker Marc Jenni.
GEOMETRY AND MECHANICS AS ONE
“With the Hoffmann, we distil our Viennese design DNA to its clearest form,” explains Robert Punkenhofer, CEO of Carl Suchy & Söhne. “We do not quote Josef Hoffmann. We think in his constructive logic. The Hoffmann translates modernist order into mechanical precision and defines time as an architectural discipline.”
The edition marks the beginning of a design line within the collection that defines mechanical architecture as a cultural principle.
