AUTOMATIC DIVER’S WATCH

Scroll down

DEVELOPMENT GUIDED BY EXTREME SUBMARINE CONDITIONS

Following the directions set out by the first diver’s watch created by Richard Mille, the RM 025, the RM 028 utilizes a number of key elements that demarcate the theme of diving within the collection. Cased in a slightly smaller diameter of 47mm, this new creation has all the hallmarks of the uncompromising character that the watches created by Richard Mille possess. Its exceptional tripartite case with unidirectional lunette and water resistance to 300 meters follows ISO diver’s watch norm 6425, creating a perfect environment to house the skeletonized movement with variable rotor geometry, a Richard Mille exclusive.

Main characteristics

300 METER WATER RESISTANT CASE. The watch 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 using torque screws that can be individually and precisely tensioned with high accuracy around the exterior circumference of the case.
This is complemented by a screwed crown construction. The lugs of all versions are in titanium, with screws to attach the rubber diving strap for maximum security.

01
CALIBER RMAS7
Skeletonized automatic winding movement with hours, minutes, central seconds, date and adjustable rotor geometry.

DATE DISPLAY Semi-instantaneous, placed in a vertical aperture in the numeral 7. The calendar disc of sapphire crystal is treated with non-reflective coating on both sides.

CALIBER RMAS7
Skeletonized automatic winding movement with hours, minutes, central seconds, date and adjustable rotor geometry.

POWER RESERVE Circa 55 hours.

Skeletonized automatic winding movement with hours, minutes, central seconds, date and adjustable rotor geometry.

BEZEL Built up of three layers connected with 22 screws, turning unidirectionally following ISO 6425 norms to avoid timing miscalculations. The use of an additional screwed system attaching the bezel to the watchcase makes it absolutely stable as well as impossible to inadvertently dislocate or loosen. In addition, the use of screws allow for perfect adjustment since the bezel is not tensioned into position. For clearer visibility under murky conditions, starting at 12 o’clock, the five-minute markers of the first quarter are highlighted red.

EIGHT-POINT-STAR-SHAPED TORQUE AND SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE

This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.
