The skeleton double flying tourbillon. Displayed here in titanium with black DLC coating, this timepiece is relatively light considering its complexity and size, titanium being 4 times lighter than gold. The only skeleton double flying tourbillon with a skeleton case on the market now comes with a power reserve indicator at 9 o'clock. Manufactured in titanium grade 5, in its natural color or with a black DLC treatement, and accessorised with a bi‑material strap, the Excalibur double flying tourbillon is a blend of innovation and tradition made to perform!
