Audemars Piguet · Automatic

AP 7129

A no-date derivative of the calibre 7121 that Audemars Piguet introduced with the 2022 Royal Oak Jumbo. Taking the date mechanism out brought the depth from 3.2 mm down to 2.8. A larger barrel and a rotor running on ball bearings with a double reverser let it hold a longer reserve at 4 Hz. It powers the [RE]Master02.
