The Vénus Calibre behind the ACE chronograph is a finely crafted and intelligently designed hand-wound movement that became extremely popular.
At an early stage in his watchmaking career, Frédéric Jouvenot became acquainted with these movements that went out of production in the 1960s, along with other collector’s chronographs. He admired them immensely and set off in search of them in order to repair, renovate and reintroduce them on the collector’s market. Around thirty of these calibres passed through his hands.
Frédéric Jouvenot then went a step further to undertake a full-fledged transformation process that resulted in the rebirth of a the hand-wound Vénus 175 as a self-winding chronograph movement named the Automatic Chronograph Evolution, for which a patent was registered in 2008.
The historical value of the movement is highlighted through the transparent case-back and honours the mechanical beauty of the original which still bears traces of a baseplate carrying the Vénus logo. Meanwhile, the most spectacular component, the oscillating weight, is magnificently staged on the dial and thus completes the total-inversion approach – since the sides have exchanged places.
To accomplish this feat, Frédéric Jouvenot maintained the architecture and structure of the movement by ensuring full visibility of the bridges, which are enhanced by hand-crafted decoration.
The gold oscillating weight moves in step with the cadence of its wearer. It is adorned with Côtes de Genève and avoids concealing the dial or counters by means of two circular openings the exact size of the minute and small seconds counters. Its creator also designed the watch case in close cooperation with his supplier. He wanted it to be extremely comfortable by rounding the lugs so as to follow the natural curve of the wrist. He also lightened up the case design by hollowing the lugs and thus giving it an extremely contemporary appearance.
The Automatic Chronograph Evolution, assembled with the original 1940 movement, is issued in a limited series numbered from 1 to 18.
