POWER RESERVE

Around 50 hours (± 10%), 45 hours with the chronograph running.

Actual power reserve results will depend on how long the chronograph is utilised.

BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM

These components in grade 5 titanium with black PVD coating confer great rigidity on the whole assembly, as well as the precise surface flatness essential for perfect functioning of the gear train.



The skeletonised baseplate and bridges were subjected to separate and extensive validation tests to ensure they met rigorous strength requirements.

FLYBACK CHRONOGRAPH

Using the pusher between 4 and 5 o’clock, the running chronograph can be reset without first having to stop the mechanism.

RUNNING INDICATOR

The running indicator is located at 3 o’clock. Thanks to both its geometry and a 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, day or night.

VARIABLE-GEOMETRY ROTOR

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.

CASE

The RM 032 Voiles de Saint Barth is characterised by its two-tone combination of Caribbean blue and white Quartz TPT®. The constant quest for optimal water-resistance and durability has led to the complete integration of these elements into a grade 5 titanium case middle. By contrast, the lugs, inserts and case back in Carbon TPT® are combined with grade 5 titanium pushers that operate the chronograph and lock the rotating bezel – a complex construction that bears the seal of Les Voiles de Saint Barth Richard Mille on the back.

LOCKING CROWN

The crown and pushers can be locked by simply rotating a ring on the crown (green index if unlocked, red index if locked). The movement is thus protected from damage due to excessive pressure or shocks to the crown. Water resistance is enhanced thanks to maximum pressure on the seals.

Finishing

Movement

• Baseplate and bridges in hand-ground grade 5 titanium, wet sandblasted, hand drawn, hand finished and PVD treated
• Burnished pivots
• Diamond-polished sinks on the bridge side
• Pinions with undercuts

Steel parts

Steel parts
• Sapphire-blasted and hand-drawn surfaces
• Screw slot and screws bevelled and polished with rounded and polished tip

Wheels

• Sandblasted and rhodium-plated, bevelled wheels (before cutting the teeth)
• Minimal corrections applied to the wheels in order to preserve geometry and performance.

Other features

FREE-SPRUNG BALANCE WITH VARIABLE INERTIA

This type of balance wheel represents the ultimate in innovation.

It guarantees greater reliability when subjected to shocks and during movement assembly or disassembly, hence better chronometric results over time. The regulator index is eliminated, and a more accurate and repeatable calibration is possible thanks to 4 small adjustable weights located directly on the balance.

DOUBLE-BARREL SYSTEM

The double-barrel system helps to improve torque stability over a longer period. This is achieved by distributing the stored energy across two winding barrels instead of one, which increases the number of rotations and reduces pressure on the teeth, bearings and pivots, resulting in better long-term performance.

SPLINE AND EIGHT-POINTED SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE

These types of screws permit better control of the torque applied to the screws during assembly. They are unaffected by physical manipulation during assembly or disassembly and age well.
