The first complication adopted by the Royal Oak was the calendar. Between 1983 and 1984, the famous octagonal watch was successively enriched with Day-Date, moon phase and perpetual calendar functions. This article reviews the origins of calendars in different civilisations, tells their history at Audemars Piguet and discusses the key stages in their deployment across the Royal Oak collection from 1983 to 1996.
Designed in one night by Gérald Genta, the first Royal Oak model was presented in 1972 at the Basel Fair, after two years of development. This extraordinary watch elevated steel to a new status. By introducing the notion of "casual chic", it opened a chapter in the history of Audemars Piguet and Haute Horlogerie
The first Royal Oak with calendar complications in addition to the aperture-type date display, Model 5572 was a response to extremely strong market demand.
On April 5, 1984, the opening day of the Basel Fair, Audemars Piguet presented the very first Royal Oak with a perpetual calendar, Model 5554, soon renamed 25554.
Model 25594 is a direct descendant of the Royal Oak Day Date 5572 created in 1983. Developed at the same time but presented a year later, Model 25594 adds a moon-phase aperture endowing the dial with remarkable aesthetic balance.
Calibre 2124/2825 consists of a basic selfwinding mechanism (2124) to which watchmakers added the 2825 cadrature, also known as the 2825 module, which indicates the day, date and moon phase.
Designed by Jacqueline Dimier and presented in 1977, the Royal Oak 4100 is also known as the Royal Oak III in the archives because it represents the third model in the collection, succeeding the 5402 and 8638.
The gemsetting of this jewellery variation of Model 25636 makes it highly recognisable. The case middle, the bezel and the links of the tapering bracelet are all entirely set with brilliant-cut diamonds.
1976年，Royal Oak皇家橡树II，即首款女装腕表Ref. 8638ST问世，是1972年推出的第一枚Royal Oak皇家橡树腕表的首个衍生表款。这或许让人颇感意外，但实际上，Royal Oak皇家橡树原型表款虽极具运动风范与男性气概，但其中亦不乏女性特质，因为珠宝设计出身的杰罗•尊达（Gérald Genta）在设计这款腕表时，希望它呈现出如钻石般丰富的光影效果。
