Zenith Academy Force Constante Georges Favre-Jacot

About this reference

Released in 2014 to commemorate Zenith’s 150th anniversary, the Zenith Academy Force Constante Georges Favre-Jacot (Reference 18.2210.4805/01.C713) was produced as a limited edition of 150 pieces in 18k pink gold. Collectors prioritize this reference for the manual-wind El Primero Calibre 4805, which integrates a fusée-and-chain transmission system designed to ensure constant force throughout the movement's 50-hour power reserve. The 45mm case features an open-dial architecture, exposing the chain mechanism between 10 and 2 o’clock and the high-frequency 36,000 vph escapement at 6 o’clock. On the secondary market, this model typically trades in the $45,000 to $65,000 range, representing a significant decrease from its original retail price of approximately $82,000. While the pink gold version is the primary reference, Zenith later released a titanium variant under the "Academy Christophe Colomb" lineage featuring similar constant-force technology but different case dimensions.
