The Manufacture

14 months.
500 components.
One movement.

Every component of a Chrono movement is manufactured, finished, and assembled in our Genève atelier by a single master watchmaker. No parallel production lines. No compromise.

Watchmaking craft
The Process
01
Conception
Each complication is drawn by hand on technical paper before a single tool is made.
02
Machining
Bridge plates and barrels are milled to tolerances of 0.001mm in our in-house tooling room.
03
Anglage
Every surface is hand-bevelled at 45° and polished to a mirror finish.
04
Assembly
A single watchmaker assembles, regulates, and certifies each movement over six weeks.
