Caliber 5134 is an extra-thin movement with a suspended barrel. The oscillating weight is guided by a peripheral ring rolling on four ruby runners that reduce friction and wear to a minimum. Moon phase indicator is laser micro-structured on an aventurine and is designed to require correction every 125 years and 317 days. Entire movement is hand finished to the finest haute horological standards. A close look at the modern AP Caliber 5134 reveals the finesse and finish of a modern Audemars movement and just a hint of its 1978 era caliber 2120/2800 parentage.
