Fragmentum Steel Grand Feu Enamel

Entirely manufactured within Oscillon’s atelier in Buchs, Switzerland, the Fragmentum is a rare modern expression of historical watchmaking methods. Every component, from the stainless steel case to the movement architecture itself, is produced using hand-operated antique machinery without CNC manufacturing or industrial shortcuts.

Created by co-founders Dominique Buser and Cyrano Devanthey, the Fragmentum is the culmination of years spent restoring vintage watchmaking tools and reviving traditional production methods rarely attempted in contemporary horology.

This particular configuration pairs the Fragmentum’s classical proportions with a pristine white Grand Feu enamel dial produced by renowned dial maker Donzé Cadrans. Blued hands, painted blue indices, a central crosshair layout and traditional railway minute track reinforce the restrained elegance of the piece.

At six o’clock sits the defining feature of the watch: a patent-pending Foudroyante complication unlike anything previously seen in independent watchmaking. The lightning seconds hand completes one full rotation per second while the underlying seconds disc rotates once per minute, creating a constantly moving and mechanically immersive display.

Visible through the sapphire caseback, the in-house manual winding calibre demonstrates exceptional traditional finishing throughout. German silver bridges, hand-polished jewel sinks, hand-finished bevels and an oversized 11.70mm balance showcase the obsessive level of detail devoted to each movement.

Measuring 38mm in diameter and just 10.45mm thick, the Fragmentum balances classical wearability with significant horological presence. Only three examples of the steel Grand Feu enamel configuration will be produced as part of the wider 12-piece Fragmentum collection.
