ASSEMBLY & QUALITY CONTROL

Numerous crafts are required to manufacture all the components of a watch. Once these components are manufactured and decorated, it falls upon the watchmaker to assemble them, adjust them, and ensure the proper functioning of the watch. Watch assembly is divided into many stages depending on its complexity. Four main assembly stages are defined for efficiency and logistical reasons:

T0: Pre-assembly of components (e.g., setting jewels and pivot holes in a mainplate).

T1: Assembly of the movement.

T2: Fitting the dial, hands, and casing.

T3: Waterproof checks and fitting the strap/bracelet.

Depending on the manufacturer’s criteria and requirements, a varying number of quality checks (functionality, adjustment, aesthetics, etc.) are carried out during the assembly stages.

 

MOVEMENT ASSEMBLY

This section sequences the different stages of assembling a movement and a watch.

QUALITY CONTROL

Whether it’s about checking the dimensions of a component, its aesthetics, or its functionality, as well as the performance of a movement or a watch, the various inspections and their possible multiple methods are described here.
