|Name:||Royal Oak Perpetual Calendar 41 White Ceramic / Blue|
The Audemars Piguet Royal Oak Perpetual Calendar 26579CB.OO.1225CB.01 is a boutique-only edition introduced in 2019. It features a white ceramic case and a blue dial with silver sub dials. It is motivated by the self-winding caliber 5134 with perpetual calendar and moon phase.
Extra-thin movement with suspended barrel. The oscillating weight is guided by a peripheral ring rolling on four ruby runners, which reduces friction and wear to the minimum possible. The moon phase indicator is laser microstructured and laid on an aventurine base. The moon phase astronomical indicator requires a correction every 125 years and 317 days. The movement is based on the earlier 2120.
