About this watch

The Audemars Piguet Royal Oak “Jumbo” Extra-Thin Openworked 16204XT.OO.1240XT.01 debuted in 2026 as an openworked execution of the original 39 mm “Jumbo” format, combining a titanium case with Bulk Metallic Glass (BMG) components. The watch is housed in a 39 mm titanium case with a thickness of 8.1 mm. The bezel, crown, and caseback are manufactured from BMG. Sapphire crystals are fitted on both the dial side and caseback. Water resistance is rated to 50 metres. The integrated bracelet is executed in titanium with BMG links and secured by a three-blade folding clasp. The openworked dial reveals the movement architecture and is framed by a silver-grey-toned inner bezel. Blackened 18-carat white-gold hands and hour markers are filled with luminescent material. The display is limited to hours, minutes, and central seconds. Powering the watch is the selfwinding Calibre 7124. The movement operates at a frequency of 28,800 vibrations per hour (4 Hz), consists of 211 components, contains 31 jewels, measures 29.6 mm in diameter with a thickness of 2.7 mm, and provides a power reserve of approximately 52 hours.
