- Movement overhaul, involving dismantling, cleaning and lubricating it so as to restore its original rate performances.
- Checking the movement and the watch functions in order to certify that the movement will perform as required.
- Repairing or replacing worn-out movement components in order to extend its durability.
- Cleaning and lubricating the escapement and the balance wheel in order to preserve the amplitude and the daily rate of the movement (mechanical).
- Replacing the battery, the source of energy of the movement (quartz).
- Adjusting the daily rate of the movement using a state-of-the-art device to simulate real-life wearing conditions.
- Cleaning the case, the metal bracelet and the buckle, using an ultrasonic device to remove dirt and grease, which are often unreachable with a standard brush.
- For the Happy Diamonds and Happy Sport watch series, the moving diamonds will be cleaned so as to restore their original appearance.
- Replacing all the gaskets and checking the water-resistance of the watch to ensure that no water or dust can enter it and thereby damage the mechanism or even stop the movement (for water-resistant watches only).
- Final quality check. Every function of the watch movement, as well as the appearance of the case or bracelet, will be verified to ensure compliance with the appropriate technical and esthetic characteristics.
