REFERENCE

Master Compressor Diving GMT

Diving bezel

Unidirectional so as to protect time measurement, it can only be moved by a force equivalent to 3 N*mm. It features a 60-tooth system enabling easy adjustment in one-minute increments. The reference triangle is luminescent to guarantee reliable calculation of dive times even in the darkness prevailing at great depths.

Maximum functionality and readability

Distinguishing day from night, the dual time-zone can be read off from 1 to 24 hours. Meanwhile, the large hour hand can be operated in a clever and useful way: simply turning the crown while it is pulled out serves to move the hand forward or backward without affecting the accuracy of the minutes.

Patented compression keys

This system is a marked improvement on the traditional screw-locked crown in three different ways. Firstly, the system is housed inside the case, sheltered from sand, dust and damp. Secondly, by remaining independent from the winding-stem, the compression key system preserves the movement from repeated strain linked to its operation.
