The Audemars Piguet Code 11.59 Perpetual Calendar reference 26394BC.OO.D027KB.01 is a 41 mm, 18-carat white-gold automatic watch with calibre 7138. Its blue aventurine dial displays the day, date, month, leap year, week and astronomical moon phases. Audemars Piguet’s US product page lists it at $120,500; that is a regional manufacturer-listed price, not a universal street price.
What is the Audemars Piguet Code 11.59 Perpetual Calendar?
It is a mechanical perpetual calendar in Audemars Piguet’s Code 11.59 collection. The documented 41 mm model is reference 26394BC.OO.D027KB.01, powered by the self-winding calibre 7138. Audemars Piguet lists its case as 18-carat white gold, with a blue aventurine dial and a blue rubber-coated strap. The Fondation de la Haute Horlogerie also describes the 41 mm watch and its all-in-one-crown correction approach in its model overview.
Case, dial and strap
The manufacturer lists a 41 mm case diameter and 10.9 mm thickness, with glareproofed sapphire crystal and caseback. Water resistance is listed as 20 m. The blue aventurine dial has white-gold applied hour markers and hands with luminescent coating, set against a blue lacquered inner bezel. The blue rubber-coated strap closes with an 18-carat white-gold AP folding clasp. These are specifications published on Audemars Piguet’s US product page and may change.
A 38 mm version also appears in the collection
Audemars Piguet’s Code 11.59 collection page also surfaces a 38 mm Perpetual Calendar. Its reference and full specifications are not established here, so the 41 mm model’s materials, movement, functions and price should not be assumed to apply to it.

How do you set the Code 11.59 Perpetual Calendar?
Calibre 7138 uses four crown positions to set the time and calendar indications, according to Audemars Piguet’s setting demonstration published March 6, 2025. The Fondation de la Haute Horlogerie characterizes its correction system as an all-in-one crown. This is a high-level description, not a substitute for the exact operating sequence: consult the current user guide for the reference before changing settings, including any precautions or restrictions.
Audemars Piguet says calibre 7138 was developed over five years. That duration is the manufacturer’s statement in its calibre 7138 video description, rather than an independently verified development history.
