CREATED FOR DEEP SEA DIVING
RM 032 AUTOMATIC CHRONOGRAPH DIVER'S WATCH
Using the pusher between 4 and 5 o’clock, the running chronograph can be reset without first having to stop the mechanism.
The running indicator is located at 3 o’clock. Thanks to both its geometry and a 2-rpm rotational frequency, it is possible to check at a glance the functioning of the running movement.
The running indicator disc is composed of successive SuperLumiNova® and black sectors; as a result, it can be easily seen, day or night.

During deep sea dives, water pressure is powerful enough to unintentionally operate one of the pushers, eg. the ‘start’ pusher of the chronograph. The possibility of a mistake manipulating the crown must also be taken into account.
In order to avoid potentially fatal consequences due to external pressure or accidental manipulation, Richard Mille developed a locking crown for the RM 032 that immobilises the pushers and ensures perfect water resistance to 300 metres.
The crown and pushers can be locked by simply rotating a ring on the crown (green index if unlocked, red index if locked). The movement is thus protected from damage due to excessive pressure or shocks to the crown. Water resistance is enhanced thanks to maximum pressure on the seals.
The pushers, their respective components and the crown require a 10-day machining phase. During this period numerous water-resistance tests and quality controls are carried out. All of these steps are crucial to obtain the specific ergonomic levels associated with Richard Mille watches.
