The Royal Oak was released in 1972 with a design by Gerald Genta, and forty years later Audemars Piguet marked the anniversary with the reference 15400. It grew to 41mm, two millimetres more than the 39mm watch that it replaced, and it received calibre 3120, a movement developed in house for the model.
The silver dial carries the Grande Tapisserie pattern, whose squares are cut deeper than those of the smaller patterns, and the light moves across it more than on a flat dial. The eight hexagonal screws of the bezel and the brushed and polished surfaces of the case are the signature of the model. Behind the dial, calibre 3120 has a single mainspring that provides 60 hours and a date with a safety mechanism, and the caseback allows the movement to be seen.
