I often imagine a case made entirely involving sapphire crystal in order to take a look at the inner mechanisms. So I ended up being very excited to see the brand-new Richard Mille RM056 Felipe Massa Sapphire Tourbillon Divide Seconds Race Chronograph (yes, that's the full name... ).
The RM056 provides you with a very sophisticated hand-wound tourbillon movement with hours, short minutes, split-seconds chronograph, power reserve along with torque indicator.
The entire case is trim and milled from a sturdy block of sapphire, a engineering challenge given typically the material's extreme hardness. Using this method a scratch-resistant case in which reveals the complexity on the mechanism.
Most bezel case parts are generally treated with an anti-glare layer for optimum optics. Every part of the movement are best, most of which are made of ti, and the total weight is no more than 10 grams.
