An intriguing variation on the original Audemars Piguet Quantime Perptual, this rose gold reference 25668OR makes every effort to display the artistry and skill required for this openworked piece. From a glimpse into the complicated inner workings to the deft hand-engraved movement, the watch is a visual feast for the wearer. It is believed that only 205 pieces were produced across the reference, with just 30 in rose-gold.

A descendant of the reference 5548, this reference 25668 was created nearly a decade later, and retains the typical layout as originally penned by Jacqueline Dimier in 1977. The perpetual calendar indications are laid out in an intuitive manner: the date and day are shown at 3 and 9 oclock respectively, with the months displayed at 12 oclock. A moonphase indication is placed at 6 oclock, with graduations for the moon position just above.

The combination of a rose gold case with silvered sub-dials leans toward the traditional, while allowing the wearer to appreciate the openworked dial without too many distracting elements. The watch also features blued hands for the sub-dials and hands in rose-gold for the hour and minute hands. Supposedly only 205 pieces were ever made across the reference, with only 30 in rose-gold. The reference 25668 was produced between the years of 1988 and 1993, and very few have been seen on the market. At 36mm, the watch is a delightful neo-vintage example that represents the exploratory spirit of the era in which it was created.

The reference 25668OR is powered by the automatic calibre 2120, an ultra-thin movement which was derived from Jaeger-LeCoultres legendary . The Caliber 2120 was an initial project of Jaeger LeCoultre in 1967, funded and contributed by Audemars Piguet, and famous for its adoption by Audemars Piguet, Patek Philippe and Vacheron Constantin. The movement can be viewed through the sapphire caseback, which displays hand-engraved patterns, in addition to beautiful finishing.
