Our showroom at 36 boulevard Raspail is open from Monday to Saturday by appointment. Our home deliveries and collections are continuing as usual taking full protective measures.

The Watch Service Center is located at Collector Square's main location.
Before any service, one of our service center managers will determine the feasibility of the service to avoid compromising the integrity and
authenticity of the item.

Movement checking and authentication

Each watch is opened and examined by our watchmakers and our resident watch expert. The movement is checked to ensure its authenticity with respect to the model of the watch and the period in which it was made.

APPRAISER'S ADVICE

A watch workshop at Collector Square

For an automatic watch
An automatic watch is wound naturally by the movements of the wrist.
If you're not wearing it for several days, it's a good idea to wind it manually by turning the crown a few times.

For a mechanical watch
A mechanical watch has to be wound every day with the crown and has a power reserve of 36 to 48 hours.

For a quartz watch
The quartz movement is the most accurate and durable movement. It requires no daily intervention and operates with a battery that we recommend changing every two years.
