This endangered species strap is shown for display purposes only and is not for sale. The watch will be supplied with a calf leather strap.
The present spectacular neo-vintage high jewellery reference 25786BA, a skeletonized perpetual calendar with moon phases, was created as a one-of-a-kind piece featuring a stunning baguette-cut emerald bezel. It embodies the pinnacle of watchmaking technology and the skill of a master jeweler.
Reference 25786BA was produced in four examples, each designated as a unique No. 1⁄1. The series includes one piece with a ruby-set bezel, one with an emerald-set bezel, one with a sapphire-set bezel, and one with a diamond-set bezel. According to Audemars Piguet literature, all four pieces of this reference were sold in 1995.
The beauty and rarity of perfectly matched coloured precious stones are widely appreciated, and for Audemars Piguet, only perfection is acceptable. Discreetly lavish, the present timepiece is one of the most elusive and exclusive of all AP’s neo-vintage gem-set timepieces. The bezel is set with carefully shaped and matched baguette-cut emeralds, and the hour markers of the dial are also set with round emeralds. The skeletonized dial is overlaid with translucent sapphire crystal, featuring green-coloured subsidiary chapter rings that perfectly complement the emerald bezel.
The movement is AP’s revolutionary caliber 2120, launched in 1978. This automatic caliber was a game-changer for Audemars Piguet, as the ultra-thin underdial work of the perpetual calendar, combined with the world’s thinnest self-winding movement, resulted in a total movement height of just 3.95 mm. In this special reference, the movement is skeletonized and hand-engraved, with the rotor pierced with the initials ‘AP.’ The perpetual calendar display of this reference does not include a four-year leap-year cycle indication, as it was produced before AP’s reintroduction of the leap-year indication in 1993. The perpetual calendar mechanism not only self-adjusts for the number of days in the month but also calculates the correct adjustments for leap years.
This magnificent one-of-a-kind emerald-set automatic perpetual calendar moon phase watch encapsulates the perfect combination of mechanical complexity, unique design, and ultimate exclusivity. Undoubtedly one of the most noble specimens of an AP perpetual calendar moon phase automatic wristwatch in existence, it offers collectors a once-in-a-generation opportunity to acquire this astonishing timepiece.
