  • Catalogue Essay

    The Royal Oak is a timepiece that set the benchmark on many fronts. Not only was it the very first luxury sports watch when launched in 1972, it was also the very first luxury sports watch featuring a complication.

    In 1982, exactly 10 years after its launch, the Royal Oak was presented with a perpetual calendar, 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 work movement, once again demonstrating the brand’s ability to think out of the box.

    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 caliber reference to 2120/2802.

    Caliber 2120/2800 was born in 1977 making it the world’s slimmest perpetual calendar movement with a thickness of only 3.95mm.

    Reference 25829 is immensely charismatic thanks to its potent blend mixing the power of the Royal Oak case and delicate subtlety of an openwork movement allowing a unique view into the perpetual calendar movement.

    The combination of sublime technical execution and unmistakable looks has over time led the collector community to consecrate this model as one of the most interesting, attractive and collectible complicated Royal Oak executions.
