Richard Mille RM028 Ti Diver

RM 028

Automatic Winding Diver’s watch

‘We created the RM 025 because we wanted to tackle the circle in all its roundness, and its creation supplied us with the technical foundation for developing the automatic movement of the RM 028. Cased in a slightly smaller diameter of 47 mm, this creation has all the hallmarks of its uncompromising character.’

DEVELOPMENT GUIDED BY EXTREME SUBMARINE CONDITIONS

Following the direction set out by the first diver’s watch created by Richard Mille, the RM 025, the RM 028 uses a number of key elements that demarcate the theme of diving within the collection. Its exceptional tripartite case with a unidirectional bezel and water resistance to 300 metres follows ISO diver’s watch norm 6425, creating a perfect environment to house the skeletonised movement with variable rotor geometry, a Richard Mille exclusive.

RM 028 AUTOMATIC DIVER’S WATCH

CALIBRE RMAS7

Skeletonised automatic winding movement with hours, minutes, central seconds, date and variable-geometry rotor.

POWER RESERVE

Circa 55 hours (± 10%).

DATE DISPLAY

Semi-instantaneous, the calendar disc of sapphire crystal is treated with non-reflective coating on both sides.

VARIABLE-GEOMETRY ROTOR

The Richard Mille RM 028 uses variable geometry to optimise the rotor’s winding motion.

Rotor specifications
• Arm in grade 5 titanium
• High palladium content 18K white gold weight segments
• Weight segment with 6 possible positions adjusted by screws in grade 5 titanium
• Ceramic ball bearings
• Unidirectional; anti-clockwise winding direction

This exclusive Richard Mille design makes it possible to effectively adapt rewinding of the mainspring to the user’s activity level, in sporting or non-sporting environments. By adjusting the six-position rib, the rotor’s inertia is modified to either speed up the winding process in the case of leisurely arm movements, or to slow it down during sporting activities.

The watch is water resistant to 30 atmospheres (300 metres) per 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 screw-lock crown construction.
