In 1983 the Royal Oak was presented with a perpetual calendar as the reference 5554, not only a rare complication at the time as very few brands were still producing them but the audacity of housing this delicate complication in a steel sports watch was mind boggling. Soon after Audemars Piguet merged its technical know how to its artistic dexterity by presenting a perpetual calendar Royal Oak with an open worked face featuring a transparent dial that showcases the intricate details of its heart, once again demonstrating the brand’s ability to think out of the box.
Notable for being the world’s thinnest full-rotor self-winding calibre, it was not until the mid 1990s that the caliber 2120/2800 housed within the Royal Oak perpetual calendar models was upgraded to feature a leap year indicator placed within the months subdial at 12 o’clock, resulting in a change of the calibre reference to 2120/2802.
Faithful to its original model with a perfectly snug 39mm diameter case on the wrist, the reference 25829 was available from 1996-2011 in all metals such as steel, pink gold, yellow gold, platinum and even tantalum, total of 1,241 pieces.
Preserved in excellent condition, the present stainless steel Royal Oak Openworked Perpetual Calendar was worn sparingly by the original owner.
