In celebration of the inaugural edition of “Les Voiles de St Barth” regatta, title sponsor Richard Mille introduces a limited edition titanium dive watch, the RM 028 Les Voiles de St Barth.

This 100-piece special edition pays tribute to the international yacht race that takes place in the Caribbean waters surrounding St Barth.

Richard Mille combined the exceptional case and skeletonized movement that has become the hallmark of all Richard Mille watches, with the specific timepiece features required of divers and sailors alike.

The RM 028 adheres to diver’s watch ISO norms 6425 with its water resistance of 300 meters (30 ATM) and a unidirectional bezel. The seemingly simple lines of the 47-mm round case conceal a considerable amount of technical know-how. The exceptional water resistance is achieved with a three part case construction and 22 torque screws, with complete integration
of the lugs into the case system. This configuration prevents any accidental dislodging of the bezel from its case while diving. The skeletonized automatic movement of the RM 028 utilizes a rotor with variable geometry, a major innovation of Richard Mille that allows the level of automatic winding to be adjusted to the user’s lifestyle via the setting of two 18K white gold wings.

The RM 028 Les Voiles de St Barth edition is distinguished by elements in bright yellow, a prevalent color in all sailing and diving pursuits. Yellow rubber protects the crown, and the vibrant shade adorn the bezel. The watch is also presented on a yellow rubber bracelet, a first for the Richard Mille collection.

Finally, the logo of Les Voiles de St Barth resides on the dial above 8 o’clock.

ROTOR WITH VARIABLE GEOMETRY

– Arm in grade 2 titanium
– Flange in grade 2 titanium
– 6-positional adjustment via grade 5 titanium screws
– Ribs in 18-carat, high palladium content white gold
– Weight segment in tungsten/cobalt alloy
– Ceramic ball bearings
– Unidirectional anti-clockwise winding direction

This exclusive RICHARD MILLE design allows the rewinding of the mainspring to be adapted most effectively to the user’s activity.By adjusting the setting of the rib’s placement, the rotor’s inertia is modified to either speed up the winding process in the case of leisurely arm movements, or slow it down when sporting activities are pursued. As a result, this invention allows the movement’s winding mechanism to be optimized.

BOTTOM PLATE, BRIDGES AND BALANCE COCK MADE OF TITANIUM

The manufacture of these components in grade 2 titanium with black PVD coating allows the whole assembly to be given great rigidity, as well as precise surface flatness which is essential for the perfect functioning of the gear train.

DOUBLE BARREL SYSTEM

The double barrel system helps to improve the stability of torque over a longer period.

This is achieved by using more turns, thereby reducing pressure and friction on the teeth, the bearings and the pivots, resulting in improved long-term performance.

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.

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.

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. The lugs of all versions are in titanium, with screws to attach the rubber diving strap for maximum security.

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.

INTERIOR FLANGE (upper and lower)
In carbon fiber, with index points filled with approved luminous material.

DIAL
In sapphire (thickness: 0.40 mm) with anti-glare treatment (2 sides), protected by 8 silicon braces inserted in the upper and lower grooves.

CRYSTAL
– Bezel side: in sapphire (1800 Vickers) with anti-glare treatment (2 sides).
– Thickness: 3.00 mm
– Case back: in sapphire with anti-glare treatment (2 sides)
– Thickness: at the center 1.90 mm and at outer edges 2.60 mm

FEATURES

– Balance spring: ELINVAR NIVAROX
– Shock protection: INCABLOC 908.22.211.100 (transparent)
– Escapement wheel jewels: Rubifix (transparent)
– Stem with three positions: manual winding, time setting, date adjustment

MOVEMENT
– Bottom plate and bridges in titanium, wet sandblasted, PVD treated
– Burnished pivots
– Diamond polished sinks on the bridge side
– Pinions with undercuts
– Sandblasted and rhodium-plated, beveled wheels.
