What happens in a watch service

A full service on a mechanical watch starts with a test. We place it on our timing machine in several positions to see how fast or slow it runs and how strong the beat is. This tells us what to look for.

Next, the movement is taken apart completely. An ordinary automatic has more than a hundred parts, some smaller than a grain of rice. Each one is inspected under magnification, and worn parts are set aside for replacement.

The parts are cleaned in an ultrasonic bath and dried. The watchmaker then reassembles the movement by hand, oiling each pivot with a different grade of lubricant, using a fraction of a drop at a time.

Once assembled, the movement is regulated on the timing machine until it runs within our limits. The case is cleaned, gaskets replaced and the watch is tested for water resistance before it goes back together.

Finally, it sits on our bench for three days so we can check it keeps time in real wear. Only then do we call you.
