We’re all acquainted with skeleton watches, however this Richard Mille tourbillon watch is much more precisely referred to like a skull watch, hence its title: the Tourbillon RM 052 Skull. The timepiece, which made its debut at SIHH 2012, was launched inside a special edition of 21 pieces — 15 in titanium and 6 unique pieces occur rose or white gold or platinum.
The watch’s signature feature, obviously, is its striking, skull-formed baseplate made from grade 5 titanium. However, it’s not only a clever design element but additionally built-into the movement: the lower and upper “jaws” contain the ruby from the tourbillon cage, and the rear of the skull can also be the movement’s center bridge. The 4 bridges that connect the movement towards the situation are arranged inside a “skull-and-crossbones” pattern inspired by flags from sailing ships. The baseplate and bridges (skeletonized, naturally) happen to be exposed to rigorous testing to make sure an advanced of strength and rigidity. The titanium alloy employed for them can also be used frequently within the aerospace, automobile and aeronautical industries because of its high corrosion-resistance.
One of the other technical touches really are a free-sprung balance, which supplies defense against shocks and enables for additional precise changes a quick-rotating barrel (six hrs per revolution instead of 7.5 hrs), which will help increase performance by diminishing mainspring cohesion a barrel pawl with progressive recoil, which will help in disbursing the mainspring’s internal tension and spline screws made from grade 5 titanium, employed for the bridges, that allow better torque control throughout set up. The tripartite situation requires 255 machining steps, including 86 rubber stamping procedures. Richard Mille makes the large situation lighter by creating openings within the bezel and caseback. The situation also uses spline screws in titanium for greater torque control, and it has a torque-restricting crown, yet another security feature to avoid accidental overwinding.
