Audemars Piguet unveils a new edition of the Royal Oak Perpetual Calendar Ultra-Thin, first introduced in 2018 as the thinnest of its kind. The new edition is presented in full titanium (case, bezel, and bracelet) and with a twist of its beautiful blue dial. With a case height of just 6.2 mm, the 41-mm watch lives up to its name. The same rings true for the self-winding manufacture caliber 5133, which was first introduced in 2017 and is a mere 2.9 mm thick.
Comprising of 256 parts, this workhorse features a special design that positions the functions of the perpetual calendar, which are usually placed on three separate levels, on a single plane. This new technical feat led to the development of two patented innovations: the integration of the end-of-month cam with the date wheel and the association of the month cam with the month wheel. To further reduce thickness, the dial also acts as a bridge.
The Royal Oak Perpetual Calendar Ultra-Thin introduces a new smoky-blue dial developed especially for this model. Light in the center and dark around the rim, it is decorated with a sunburst motif endowing it with luminous aesthetics. The deep background hue make the calendar indications, month and leap year at 3 o’clock, date at 6 o’clock, day and day/night indicator at 9 o’clock all the more legible.
The moon phase at 12 o’clock is the only indication whose design has not been modified from the previous model. The dial remains punctuated by twelve luminescent applied hour-markers and two central hands, likewise luminescent.
Pricing for the new Audemars Piguet Royal Oak Perpetual Calendar Ultra-Thin is available upon request.
