OUR MOST COMPLICATED AUTOMATIC CALIBRE
RM 65-01 AUTOMATIC SPLIT-SECONDS CHRONOGRAPH
Semi-instantaneous, placed in a vertical aperture at 11 o’clock.
The RM 65-01 is constructed with a highly specialised gearbox design for Winding, Date and Hand Setting functions. To shift back and forth through these different functions, use the pusher located at the centre of the crown until the desired function is selected.
The hand located at 4 o’clock will indicate W, D or H accordingly.
HIGH FREQUENCY BALANCE WITH VARIABLE INERTIA
Beating at 5Hz (36,000 vph), the fast-beating free-sprung balance offers better reliability in the event of shocks, movement assembly and disassembly, and also guarantees better chronometric results over an extended period of time, keeping a more accurate time. This new type of balance at Richard Mille can measure accurately to 1/10th of a second, ideal for a split-seconds chronograph watch under sporting conditions.
The regulator index is eliminated, and a more accurate and repeatable adjustment is possible thanks to 4 small, adjustable weights located directly on the balance.
Movement dimensions: 31.78 x 29.98 mm
Thickness: 8.69 mm
Balance: Glucydur®, 4 arms, moment of inertia 7.5 mg•cm2, angle of lift 53°
Frequency: 36,000 vph (5 Hz)
Balance spring: AK3
Index assembly: Triovis n° 2
CASE IN CARBON TPT®
Carbon TPT® is almost indestructible and possesses exceptional physical properties that make possible a lighter case offering ideal shock protection.
Carbon TPT® consists of over 600 layers of parallel filaments obtained by separating carbon threads. With a maximum thickness of 30 microns, the Carbon TPT® layers are saturated with matrix, then compiled on a special machine that modifies the orientation of the fibres between each layer by 45°. Once it has been heated to 120°C and subjected to a pressure of 6 bars, the Carbon TPT® is machined at Richard Mille’s factory.
Carbon TPT® is renowned for its excellent resistance to micro-cracks and splits.
The complete case construction is water-resistant to 50 metres thanks to two Nitrile O-ring seals and is assembled using 20 spline screws in grade 5 titanium and 316L stainless steel washers.
