Zenith Unveils the Defy El Primero Fusée Tourbillon : A Modern Reinterpretation
Zenith unveils their modern reinterpretation of the fusée & chain constant force mechanism with the new Defy El Primero Fusée 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 fusée & chain constant force mechanism in a modernist style with their new Defy El Primero Fusée Tourbillon.
The timepiece is adorned in a bicolour finish, where the top satin-finished surface is given a black treatment, while its polished sides are a lighter grey rhodium tone, that in turn amplified the spoke design of the bridges. 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 uniquely conceived fusée and chain constant force mechanism.
The chain, comprising 575 individually hand-assembled components and features a bold blued treatment, is a first of its kind for a wristwatch fusée and chain system. 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 is adorned in a striking blue colour, reinforcing the visual effect of the Defy El Primero Fusée 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 El Primero Fusée Tourbillon with its 50-hour power reserve.
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, the Defy El Primero Fusée Tourbillon is available in two distinct editions: Carbon and Platinum.
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 shimmer of this material. To complete the high-tech look, the Defy El Primero Fusée Tourbillon in carbon is fitted on a black rubber strap with a “Cordura” fabric effect and blue stitching. A second strap in black rubber with a woven carbon effect is also supplied. The Defy El Primero Fusée Tourbillon in carbon is limited to 50 pieces.
The second version of the Defy El Primero Fusée Tourbillon, limited to just 10 pieces, 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 plate of the movement to the blued chain and tourbillon cage topped with a set of geometrical bridges in two tones. The strap is made of a black rubber core coated with black alligator leather.
Zenith Defy El Primero Fusée Tourbillon timepiece boasts a diameter of 44 mm and a thickness of 13.35 mm. It is also equipped with domed sapphire crystal with anti-reflective treatment on both sides and is water resistant up to 10 ATM.
