The aesthetic is reminiscent of a unique, historic tank design from Audemars Piguet from the mid-1920s. The 25682BA is distinguished by its elegantly curved rectangular case, subtly reminiscent of understated Art Deco sophistication. Symmetrical, geometrical, and elongated, this specific piece looks back to early 20th-century design.
The dial integrates the traditional layout for a perpetual calendar, though subtly reworked for its rectangular shape. The sub-dial at 3 o’clock shows the date, in a noticeably recessed sub-register, giving depth to the otherwise smooth silver dial. In a similar fashion, the days of the month are placed at 9 o’clock, with the months of the year at 12.
The moonphase is placed at 6 o’clock. The depth of the sub-dials, and their light circular finish, gives the watch an even more distinctive appearance on the wrist. As opposed to the painted Breguet numerals that can be found on similar iterations of this model, the hours are marked by yellow gold indices, which are further complemented by yellow gold hands.
This Quantième Perpetuel 25682BA is powered by the manual-wind calibre 2003. The base movement, developed in conjunction with ébauche maker Jaeger-LeCoultre, was first developed in 1946, remaining in production for half a century. On top of it, Audemars Piguet added their 2805 QP perpetual calendar module, giving the movement a total thickness of only 3.19mm. The movement is beautifully finished, with exquisite chamfering on all angles, polishing, and decoration, in the form of Geneva striping.
