With the help of a specific device "Witschi Analyzer Q1" performs the diagnosis, it is intended to know if the clock needs only to replace the battery or if you have any more: in electronics or mechanics. There is:
- The battery voltage
- The motor impulses
- The resistance (s) coil (s)
- Intakes
- The operational limits (upper and lower)
- The adjustment
If the battery is flat and the movement is within the tolerances designated by each brand for that specific caliber, it will be replaced. The joint fund is also changed and made ??the (Witschi master Proof) hermeticity test, when it comes to a waterproof model. The clock is washed by ultrasound and delivered to the customer, accompanied by appropriate diagnostic tests and hermeticity.
