Proudly displaying unobstructed views of cutting-edge Zenith mechanics: the Academy Tourbillon Georges Favre-Jacot offers a futuristic take on Haute Horlogerie. Its powerful design and innovative materials reveal an unprecedented ‘engine’ – El Primero Calibre 4805 – combining two iconic complications from the Manufacture: the tourbillon and a fusee and chain transmission system. Issued in a 150-piece limited edition featuring a 45 mm-diameter black ceramic case, this sophisticated watch fully reveals the contemporary architecture of its high-frequency heart.
Eloquently expressing the comprehensive manufacturing expertise cultivated by Zenith, the Academy Tourbillon Georges Favre-Jacot flaunts its mechanism in an entirely transparent manner. Its virile black ceramic case houses a new El Primero movement equipped with a tourbillon as well as a fusée and chain transmission system. These two horological complications, both specialities of the brand with the guiding star, are thus united for the first time in a Zenith high-frequency movement. The dial-free hand-wound El Primero Calibre 4805 provides a perfect picture of its magnificent mechanisms and its powerful architecture.
Haute Horlogerie meets modernity in this remarkable fusée and chain tourbillon model, equipped with the new high-frequency El Primero Calibre 4805, entirely developed and produced in-house by Zenith. While its famous name and its fast cadence of 36,000 vibrations per hour recall the legendary chronograph created by Zenith in 1969, this original new ‘engine’ also features a majestic tourbillon coupled with a fusée and chain transmission system linked to the barrel so as to ensure constant force.
A fascinating compendium of watchmaking technologies, this 807-part hand-wound movement is composed of modern, well-structured lines. The dial-free Academy Tourbillon Georges Favre-Jacot with its generously sized 45 mm-diameter black ceramic case turns the spotlight on its tourbillon placed at 6 o’clock and on its fusée and train transmission system between 10.30 and 1.30. Secured to the mainplate by polished screws, three blackened bridges support the fusée and barrel arbors, while the tourbillon carriage performs one rotation per minute. The central hours and minutes functions are shown on a ring swept over by luminescent black facetted hands and hour-markers. The more than 50-hour power reserve is displayed between 4 and 5 o’clock by a red-tipped hand moving between “High” and “Low” indications. Visible both on the display side and through the sapphire crystal case-back, the mainplate and bridges are coated with a deep anthracite colour adorned with alternating sandblasted, hand-chamfered and straight-grained finishes.
Water-resistant to 50 metres, the Academy Tourbillon Georges Favre-Jacot is fitted with a perforated rubber strap secured by a PVD-coated titanium triple folding clasp and issued in a 150-piece limited edition. Another 150-piece rose gold limited-edition version is also available.
