Brought to life by Gerald Genta in 1972, the design of the Royal Oak meets a growing success nowadays and is considered as one of the most important icon in the modern watchmaking history. Produced from 1982 to 1993, the ref. 25654 embodies the knowhow of Audemars Piguet which is the first manufacture to produce a luxury sports watch featuring a complication. Out of a total production of 800 pieces in all metal combined, 422 were made in yellow gold, 272 in stainless steel, 72 two-toned, 33 platinum and 1 white gold. Combining a perpetual calendar movement to a sports watch was, at the time, a very “avant-garde” way to approaching horology. The Champagne dial features the "Audemars Piguet" signature in small lettering, only found on the earlier examples of the reference 25654, before the brand adopted its modern signature style.
