Richard Mille Rafael Nadal Chronofiable Watch, tonneau-shaped magnisum/aluminium alloy case (48mm length x 39.7mm width x 12.25mm thickness) with solid caseback, eight titanium spline screws hold together the case for better control of torque during assembly, skeletonized dial with luminous index markers and hands, sweeping seconds hand, 24 jewels calibre #RMUL1 manual-winding movement, 55 hour power reserve, scratch resistant sapphire crystal, water resistant to 50 meters.
The Chronofiable test was developed at the beginning of 80?s by the CCF SA (centre de contr?le de la fiabilit? de l?horlogerie Suisse taken over in 1985 by the Laboratoire Dubois SA), in order to simulate accelerated aging of watches. This simulates normal wearing conditions with an accelerated intensity factor of about 8 by reproducing, over 21 days (the equivalent of 6 months effective wear).
These tests include:
- initial monitoring of the movement functions and an additional rate and amplitude test, at two temperature levels (0?C and 50?C); monitoring of the power reserve and the winding velocity.
- numerous tests of the stem.
- ageing cycles consisting of linear and angular accelerations; 20,000 shocks ranging from 250 to 5500 m/s2 (9.81 m/s2 = 1g) as well as changes in temperature and humidity during these cycles.
- tests with magnetic fields.
- final monitoring with same elements than during the initial monitoring.
The RM 035 Rafael Nadal Chronofiable certified, confirms the ability of the RMUL1 caliber to withstand many extreme conditions without experiencing any effects on its performance. These tests confirmed that the caliber RMUL1 was able to withstand shocks according to the norm ISO 1413.
