Upon a first glance, it’s immediately clear that the Defy Fusee Tourbillon’s calibre is out of the ordinary. The spoke design of the bridges is amplified by their bicolor finish, where the top satin-finished surface is given a black treatment, while its polished sides are a lighter grey rhodium tone. The layout of the bridges offers a balanced layout of the various functions and complications. On the top half of the movement, one can admire the fusee and chain constant force mechanism. The chain, which consists of 575 individually hand-assembled components, features a bold blued treatment. On the opposite end at 6 o’clock, a tourbillon cage with an off-centered balance wheel makes a full rotation every 60 seconds. Like the chain, the tourbillon cage is embellished with a striking blue colour, reinforcing the visual effect of the Defy Fusee Tourbillon’s unique moving parts. Positioned at the edge of the dial between 4 and 5 o’clock, a red-tipped hand indicates the power reserve, a handy feature when manually winding the Defy Fusee Tourbillon with its 50-hour power reserve.
The first version, limited to 50 pieces, features a light yet robust carbon case, crown and buckle head. The carbon fibre treatment even extends to the open dial, with the central skeletal element and surrounding flange ring giving off the unique shimmer of this material. The second version of the Defy Fusee Tourbillon, limited to just 10 pieces, is crafted in platinum.
