Deep down technicity
The RM 032 combines the practical features of timekeeping on land along with the exotic and harsh environmental conditions experienced by Arnaud Jerald.
RM 032 Automatic winding flyback chronograph Les Voiles de Saint Barth
Automatic winding movement with hours, minutes, oversize date, month, flyback chronograph with minutes and seconds counter, hour counter, running indicator and variable-geometry rotor.
Limited edition of 120 pieces.
Around 50 hours (± 10%), 45 hours with the chronograph running.
Actual power reserve results will depend on how long the chronograph is utilised.
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.
Using the pusher between 4 and 5 o’clock, the running chronograph can be reset without first having to stop the mechanism.
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.
OVERSIZED DATE DISPLAY
Semi-instantaneous, placed in a horizontal aperture below 12 o’clock, with automatic adjustment for months of 30 or 31 days.
Semi-instantaneous indicator with Arabic numerals placed between 4 and 5 o’clock.
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 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.
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.
• 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
• Sapphire-blasted and hand-drawn surfaces
• Screw slot and screws bevelled and polished with rounded and polished tip
• Sandblasted and rhodium-plated, bevelled wheels (before cutting the teeth)
• Minimal corrections applied to the wheels in order to preserve geometry and performance.
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.
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.
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.
