From this moment, every measurement taken on this movement is individually tracked.
A watch does not stay in one position. It moves with you throughout the day. This sequence measures how precisely the movement keeps time in each position it will encounter on the wrist.
Temperature changes the rate of a mechanical movement. A warm wrist on a cold day, a watch left on a bedside table overnight. This sequence measures how the movement responds to a 30-degree variation.
After 15 days of continuous operation, the movement’s precision is compared against its own first results.
Precision applies to everything.
