The maintenance service is the ideal opportunity to bring your watch in for a periodic inspection to maintain its technical qualities. It also enables any malfunctions to be identified. Our watchmakers make a thorough diagnosis and run through the various checks on the movement and the watch’s resistance to magnetic fields and water, for a quartz watch after changing the seals and battery. The metal case and bracelet are carefully cleaned. We recommend that you service your watch every two years, alternating between a maintenance service and a complete service. This service requires between one and a half and two hours, and involves over 48 hours of testing. If any of the checks gives a negative result, a complete service is required. After this service, you will be issued with a 12-month service guarantee, covering the work and parts replaced.
