Description
The Audemars Piguet Royal Oak Perpetual Calendar reference 26574ST.OO.1220ST.01 was introduced in 2015. At 41mm, its case is slightly larger than its predecessors. Accordingly, the self-winding caliber 5134 is slightly larger as well - plus a week number indicator has been added. In this configuration, case and bracelet are stainless steel; the dial is silver and features the famous 'Grande Tapisserie' pattern.
Movement
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.
