Richard Mille RM 032 Automatic Chronograph Diver's Watch
Created for deep sea diving. The RM 032 offers hours, minutes, seconds, a 12-hour totaliser and flyback-chronograph functions, combined with an annual calendar sporting an oversized date at 12 o’clock and a month indicator (with numbers from 1 to 12) between 4 and 5 o’clock.
The RM 032 also possesses a running indicator, located at 3 o’clock. Thanks to both its geometry and 2-rpm rotational frequency, it is possible to check the correct functioning of the running movement under stressful, dimly lit conditions.
The RM 032 is water resistant to 30 atmospheres (300 meters), following ISO 6425 diver’s watch norms. This is achieved with a unique, curved, tripartite case design. It is complemented with a screwed crown construction and the integration of the lugs in the case. The lugs of each RM 032 version have screws that optimally fasten the diver’s rubber strap.
Locking crown. During deep sea dives, the water pressure on the pushers and crown is powerful enough to unintentionally operate one of the pushers, eg. the “start” pusher of the chronograph. We also need to take into account that making a mistake with the crown is also a possibility.
In order to avoid any external pressure effect or accidental manipulation, Richard Mille developed a locking crown for the RM 032 that is able to lock the pushers and ensure perfect water resistance to 300 meters.
The crown and pushers can be locked by simply rotating its ring (green index if unlocked, red index if locked). The movement is prevented from being damaged because of overpressure or shocks on the crown. The water resistance is enhanced thanks to maximum pressure on the seals. This innovative device is specific to the RM 032 and is patent pending.
Calibre RMAC2. Automatic winding movement with hours, minutes, seconds, oversize date, month, flyback chronograph with minutes and seconds counter, hour counter, running indicator and adjustable rotor geometry.
The running indicator is located at 3 o’clock. Thanks to both its geometry and 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 during day or night.
By using the pusher between 4 and 5 o’clock, the running chronograph can be reset without first having to stop the mechanism. This was originally developed for pilots in order to not waste time (and therefore accuracy) from stopping, resetting and starting the chronograph whilst crossing a navigational point.
Function: the user can start or stop the chronograph function via the pusher located between 1 and 2 o’clock. The flyback function can be continuously reset by depressing the second pusher located between 4 and 5 o’clock.
