Description

The Audemars Piguet Quantième Perpétuel Skeleton, reference 25558BA, is a stunning example of high horology, showcasing the brand’s dedication to technical mastery and exquisite craftsmanship. Encased in 18k yellow gold, this timepiece is part of Audemars Piguet’s celebrated perpetual calendar collection, revered for its complexity and aesthetic appeal.

Measuring 36mm, the yellow gold case exudes timeless elegance and sophistication. Both the front and back are protected by sapphire crystal, allowing an unobstructed view of the intricate skeletonized movement. This open-work design reveals the watch’s inner workings, emphasizing the meticulous craftsmanship behind its perpetual calendar functions. The skeletonized dial is adorned with applied yellow gold markers, perfectly complementing the case while adding a luxurious touch to the overall design.

At the heart of the 25558BA is the Caliber 2120/2802, an ultra-thin self-winding movement. This movement not only powers the watch’s perpetual calendar functions—including day, date, month, leap year, and moon phase—but also provides a 40-hour power reserve. Its exquisite finishing, featuring Geneva stripes and circular graining, can be admired through the transparent case back, highlighting the artistry of Audemars Piguet’s watchmakers.

The perpetual calendar complication, one of the most sophisticated in watchmaking, automatically adjusts for the varying lengths of months and leap years, ensuring the watch will not require correction until 2100. The moon phase indicator at 6 o’clock adds both function and beauty, tracking the lunar cycle with precision.

Audemars Piguet – bio

Audemars Piguet is a Swiss manufacturer of mechanical watches founded in 1875. They began in the Vallée de Joux. Jules Louis Audemars formed a partnership with Edward Auguste Piguet. Audemars created complicated blank watch movements for other manufactures to use. Piguet specialized in the final regulation of watches. They then split responsibilities when they began their own company. Audemars was in charge of production and technical aspects while Piguet focused on sales and management. One of their first achievements was creating the first repeater wristwatch in 1892 and in 1972 the iconic steel “Royal Oak”.
