1. INITIAL INSPECTION AND DIAGNOSIS
A watchmaker performs an overall check of the functions, of the general appearance and of the performance of the watch before establishing a diagnosis.

2. PRELIMINARY OPERATIONS

The  watchmaker then opens the case and takes out the movement (with the hands and dial) in order to check the functions, the rate, the lubricants and the presence of any defective components.

3. COMPLETE REVISION OF THE MOVEMENT

The movement is entirely disassembled. Each component is checked and replaced if necessary, while the other components are cleaned in a mechanical ultrasonic bath. The movement is reassembled and lubricated. The adjustment is made by the watchmaker, in order to regain precision according to ZENITH quality standards.

7. REPLACEMENT OF ALL THE GASKETS

All gaskets are replaced (those fitted on the caseback, crystal, bezel, tube, crown, pushers and correctors where applicable)

6. PERFORMING ADDITIONAL OPERATIONS

All optional interventions or additional operations (replacement of the crystal pusher, engraving, etc.)

5. TEST OF THE MOVEMENT'S OPERATION AND FUNCTIONS

The watchmaker will carry out the following checks: running control in five positions, check of functions, check of autonomy and check of automatic winding.

9. CLEANING OF THE CASE AND BRACELET

The case and the metal bracelet are cleaned in an ultrasound bath.

8. POLISHING OF THE CASE AND BRACELET DEPENDING ON THE MATERIAL

The case and its various parts are entirely disassembled. Then, the case, the crown and the pushers are refinished as best as possible, to return the aesthetics of the original product. The bracelet is also refinished, in the same manner as the case.

10. CASING UP THE WATCH, FINAL AESTHETIC AND FUNCTION CHECK

The dial and hands are fitted and adjusted on the movement, then assembled in the case. Before being delivered to you, the watch's functions are checked by the Quality Assurance department, which conducts checks of: automatic winding, rate test in the five positions, power reserve,  and water-resistance checks according to the watch's specifications, and a final aesthetic control.
