AUTOMATIC CHRONOGRAPH CREATED FOR DEEP-SEA DIVING

Performance, safety, efficiency, beauty, ergonomics: they all come together in this model. The sense of security is felt as soon as you look at this instrument thanks to the visibility of its functions, its easy-to-use controls and the accuracy of the information it displays. At 300 meters under water, there is no room for error.

A second crown is added which, when rotated once, locks the push-pieces and crown so that no functions can be actuated by accidental pressure or a manipulation error. This same principle applies to the bezel, a technical miracle, which can only be manipulated by using two push-pieces to ensure total safety. It’s operating accuracy and water-tightness are the subject of countless checks throughout the fitting and assembly process of the mechanical components. The case in three parts, requires 830 machining operations, and its absolute ergonomic perfection is achieved through manual brushing and polishing.

Case:
The RM032 is water resistant to 300 meters (30 atmospheres), 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 horns in the case. The lugs of each RM032 version have screws that optimally fix the diver’s rubber strap. In the world of horology, the case of the RM032 is one of the most difficult to manufacture. After a 1h30-hour turning phase, this tripartite case has to undergo 830 operations planned during an 9-hour milling phase. After a 11-hour machining phase, each case has to pass a full day of quality control. The pushers and their respective components and the crown require a 10-day machining phase. Within this period, numerous water resistant tests and quality controls are carried out and also the hand brushing and polishing of the case. All of these steps are paramount to obtain ergonomic levels specific to Richard Mille Watches.
