Zenith Defy El Primero Fusee Tourbillon

Since the dawn of precision timekeeping, watchmakers have sought to produce timepieces that offer unfaltering performance through the use of constant force. Zenith reinterprets the fusee and chain constant force mechanism in a modernistic style in the new Defy Fusee Tourbillon.

The Defy Fusee Tourbillon is available in two distinct editions in Carbon and Platin. The first version 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 simmer of this material. The second version of the Defy Fusee Tourbillon is crafted in platinum. The exposed movement provides a vibrant, voluminous view, where the mix of materials and tones add visual depth, from the anthracite base of the movement to the blued chain and tourbillon cage topped with a set of geometrical bridges in two tones.

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 balance of the various functions and complications. On the top half of the movement, one can admire the uniquely conceived fusee and chain constant force mechanism. On the opposite end at 6 o’clock, a tourbillon cage with an entirely new construction featuring an off-centered balance wheel makes a full rotation every 60 seconds. Like the chain, the tourbillon cage comes in a striking blue color. 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 Defy El Primero Fusee Tourbillon is housing the new El Primero 4805 SK calibre, a manual-winding movement that follows the Defy code of avant-garde movement architecture with an open three-dimensional impact. By combining the fusee and chain mechanism with a tourbillon regulating organ, Zenith places precision at the forefront of its unique take on haute horlogerie.

The Defy Fusee Tourbillon in carbon is limited to 50 pieces, the second version in platin will be available only 10 times.
