Similar to common aviation practice, each functional unit of a mechanical watch - in our case the movement in particular - should be completely dismantled and checked for any signs of wear every five years. The forces within the movement are transferred via many axles, with each axle pin running in mainly low-friction ruby bearings and lubricated with the finest oils. Despite ongoing technological advances, lubricating oils still have a limited lifetime - bearing friction increases when the oil's lubricating effect starts to deteriorate, resulting in the hazard of possible damage to the bearing pin.

If no signs of wear are detected, each component is cleaned in special media and then reassembled with fresh oils and the necessary care.

Worn parts are replaced before greater damage is sustained.
