·2 mins
Zenith turned 160 in 2025. They marked it by resurrecting one of the most decorated movements in Swiss history.
The GFJ houses a modernized Caliber 135 - the hand-wound movement that won over 230 chronometry awards between 1950 and 1960. No other movement in history has matched that record.
