The latest opus by Ferdinand Berthoud
The Naissance d’une Montre (Birth of a watch) 3, dedicated "au temps qui instruit" ("to time, the great teacher"), in the words of Louis Berthoud, Ferdinand Berthoud’s nephew, is a horological heritage project, which has given birth after six years of work to a wristwatch officially chronometer-certified by the COSC and handcrafted using traditional tools, without digital assistance.
To bring the project to fruition, a collection of vintage machine tools from the 1950s and 1960s were regrouped in a single area within the Manufacture in Fleurier: the Atelier Tradition. This entity encompasses a small team of micro-mechanical engineers responsible for producing the movement components without the use of computer numerical control (CNC) machines.

Naissance d’une Montre 3 is an 11-piece limited-edition chronometer. The very first and only one of the series, featuring a stainless steel case, will be auctioned by Phillips in association with Bacs & Russo in November 2025. The next ten, made of 18-carat ethical gold, will be produced at a rate of two per year starting in 2026.
The watch, deeply rooted in the heritage of the Master Watchmaker Ferdinand Berthoud, features a constant force via a fusee-and-chain transmission system, a bimetallic balance, a central seconds hand and an open structure.

Inspired by Ferdinand Berthoud's Astronomical Watch No. 3, the 44 mm-diameter, 13 mm-thick case features curved sides, a wide fluted and engraved crown, a domed glass, a concave bezel and welded lugs.
