Audemars Piguet Royal Oak Diamond Stainless Steel Ladies Watch 67621ST.ZZ.1230ST.01

1967 was a milestone year for Audemars Piguet, which set a new record for slenderness when its self-winding Calibre 2120, the thinnest movement in the world equipped with a solid gold central rotor, emerged from the company workshops in Le Brassus. It measured a mere 2.45 mm thick! Several years later, in 1978, Audemars Piguet once again caused a sensation with the first extra-thin (barely 4 mm thick) self-winding perpetual calendar movement, thereby impressively pursuing its almost century-old tradition of expertise in calendar watches.
Jules Audemars Perpetual Calendar
In 2008, the watchmakers in Le Brassus paid tribute to the first perpetual calendar by creating a platinum limited series to mark its 30th anniversary.
Today, the Jules Audemars Perpetual Calendar is making its grand entrance into the collection with an 18-carat pink gold case, teamed according to personal preference with a brown or silvered dial. The latter features a satin-brushed sunburst finish and refined pink gold hour-markers. Its case echoes the identity codes developed in 2008 with a particularly slender bezel designed to highlight the dial.

The perpetual calendar mechanism admirably reproduces the specific features of our Gregorian calendar, taking into account the irregular lengths of the 30- and 31-day months by means of a cam - itself connected to a wheel - bearing the different monthly durations. Another wheel on the same axis, which carries a cam indicating a normal month of February and a leap-year February, performs one full revolution in four years and thus enables the watch to keep track of the leap-year cycle. This means the Jules Audemars Perpetual Calendar will not require any correction until March 1st 2100. All that will be required on this date is to activate the correctors placed on the side of the case, and the mechanism will be duly readjusted for another century. This module, built on the extra-thin self-winding Calibre 2120 base movement, was and still is - after successive enhancements - an impressive technical accomplishment and a prodigious feat of miniaturisation..
Jules Audemars Extra-thin
This year, the Jules Audemars collection welcomes an elegant new version featuring an understated design inspired by the Reference 5271 model created to mark the launch of the extra-thin Calibre 2120.

Featuring contemporary dimensions and sleek, pure lines, this timepiece proudly displays its beating heart, the timeless movement introduced in 1967 and considered by many specialists as "the world's most beautiful self-winding movement". Calibre 2120, entirely designed, developed and crafted by the Manufacture Audemars Piguet, is an integral part of the history and the legend that forged the brand's reputation in the field of extra-thin mechanical movements.
At less than 7 mm thick, the new Jules Audemars watch is entirely in line with this exceptional continuity. The reliability and performance of its movement are matched by the exquisite finesse of its decorations stemming from the meticulous care lavished by watchmakers on finishing all the components. The mainplate alone features five different diameters of circular graining. All the bridges are chamfered and polished by hand. A connoisseur's eye will revel in the remarkable craftsmanship devoted to the exterior and internal angles. Even the hidden surfaces have been treated with particular care, such as the lower part which is circular grained.

The pink gold case is also beautifully finished, with regular circular graining on the interior and a set of finely executed and complex finishes playing on alternating vertical and horizontal satin-brushed zones that create a striking contrast with gleaming polished areas. The extremely slender bezel enables a generous dial opening that contributes to the sense of visual lightness. The model comes in two versions with a silvered or black dial, adorned with dainty pink gold hands and hour-markers. This more contemporary model gives fresh impetus to the Jules Audemars collection while preserving the essence of classicism and perpetuating watchmaking traditions through this magnificent movement with its extra-thin profile and hand-crafted decoration. Over the years, Audemars Piguet has consistently cultivated its history, pursuing ever more advanced technical and aesthetic challenges while never losing sight of the traditional values that have governed it for over 135 years: the Jules Audemars Perpetual Calendar and the Jules Audemars Extra-thin are an eloquent tribute to this time-honoured philosophy.
