About this watch

The Audemars Piguet Royal Oak Selfwinding Chronograph 26450ST.OO.1356ST.01-B was introduced in 2026 as part of the updated 38 mm Royal Oak Chronograph range, replacing the 2019-generation models with a fully in-house chronograph calibre. The watch is housed in a 38 mm stainless steel case with a thickness of 11.1 mm. Sapphire crystals are fitted on both the dial side and the caseback. Water resistance is rated to 50 metres. The integrated stainless steel bracelet is secured by a three-blade folding clasp. The dial features a blue Grande Tapisserie pattern with tone-on-tone chronograph counters. It is fitted with 18-carat white-gold hands and hour markers filled with luminescent material and framed by a rhodium-toned inner bezel. The display includes hours, minutes, central seconds, a date indication, and chronograph registers. Powering the watch is the selfwinding Calibre 6401, visible through the sapphire caseback. The movement operates at a frequency of 28,800 vibrations per hour (4 Hz), consists of 350 components, contains 44 jewels, measures 27 mm in diameter with a thickness of 5.7 mm, and provides a power reserve of approximately 55 hours.
