Designed with utmost care, handmade and incorporating leather, the Watch Analyzer’s support can be produced according to specific customer requests for colors, hides, or skins.

Full watch diagnosis

The full report for your watch includes measuring the mean rate variation and the difference in amplitude between horizontal and vertical positions.

6 positions

The Watch Analyzer will tell you much about your watch, as it is designed to measure all positions used by the Swiss Chronometer Testing Institute (COSC).


The Watch Scope takes care of a full watch collection and records all measurements in its database. In that way, you can follow all timepieces over the years and detect when each should be serviced.
