WHAT'S BEING DONE TO THE MOVEMENTS

 
The crown wheel and ratchet wheel are removed along with all of the back facing screws of the watch and being refinished.

The crown and ratchet wheel are turned on a lathe while being rubbed by a spinning abrasive giving them a snailed style graining.

The screws are heat treated blue by hand on a flame heated brass plate.

The balance regulator may be adjusted if the watch does not meet our timing standards from the Sellita factory.
Vacuum tests for low pressure resistance (-0.7 Bar).
Pressure tests for water resistance (10-20 Bar).
Drop tested to exceed the ISO 1413 shock-resistance standard.
Multi-point Visual inspection.
Watch moments are timed and regulated in six positions to ±5 seconds per day of rate change or better.
72 hour active motion test.
