WATCH

The front two bubbles tell the hour on the left and the minutes on the right. The central sapphire crystal dome houses a tourbillon which has an articulated titanium cover that can be raised and lowered by the wearer. The rear two bubbles contain the twin spherical turbines that automatically regulate the winding system in case of excessive speed to reduce stress and wear.  Very technical and very complicated.

Watches like this continue to astound me due the amount of research that goes in to the design and the movement. The sapphire crystal is incredibly hard to do as each dome is shaped from a block of crystal. Out of every 100 there is about an 80% reject rate. Incredibly time consuming and costly. Makes you appreciate why mechanical timepieces like this cost what they do.
