Chronomax

The COMAX label has its own requirements that go beyond conventional chronometer tests such as COSC or LMET. While only the movement is tested for COSC and only the watch itself for LMET, both are tested in-house for COMAX. In addition, the COMAX label covers more temperature ranges and more days than the conventional chronometer tests. Each Chronomax movement is given its own engraved number and certificate number.
