The new Richard Mille watch is animated by a complicated movement that weighs just 4,3 grams - the caliber RMUL1. The manual winding, skeletonized movement has become the first manual winding movement of the brand that received the Chronofiable certification.
The Chronofiable test exposes watches to accelerated ageing testing that lasts 21 days and equals to 6 months of effective wearing. The tests include checking the movement functions, an additional rate, the amplitude test fulfilled at two temperature levels -0°C and 50°C, as well as checking the power reserve and the winding velocity. The tests also imply comprehensive linear and angular accelerations and about 20,000 shocks. The tests proved the caliber’s ability to withstand extreme conditions maintaining its flawless performance.
The 24-jewel movement, beating at 28, 800 vibrations per hour, incorporates a free sprung balance with variable inertia. The innovative balance wheel provides supreme reliability and shock-resistance. Four small adjustable weights positioned directly on the balance allow a more accurate and repeatable adjustment.
The creators of the RM 035 watch opted for magnesium-aluminum material for the case. This extremely rugged and light alloy comprises 90% magnesium and 8.9% aluminum. The surface of the case boasts great hardness and scratch-resistance, not to mention wear and corrosion resistance.
The case construction of the Richard Mille RM 035 Rafael Nadal watch is provided with two Nitril O-ring seals to guarantee 50-meter water-resistance. The case also incorporates 12 spline screws crafted in grade 5 titanium and abrasion-resistant washers in stainless steel.
