Audemars Piguet Royal Oak Perpetual Calendar Titanium Limited Edition — Salmon Sunburst Dial | Ref. 26615TI.OO.1220TI.01

Titanium and salmon are two materials that rarely share a stage in haute horlogerie, yet reference 26615TI.OO.1220TI.01 proves their pairing utterly inspired. This limited-edition Royal Oak Perpetual Calendar — produced between 2020 and 2022 — houses the celebrated Calibre 5134 perpetual calendar movement within an exceptionally lightweight 41mm grade 5 titanium case that sets new standards for comfortable wear in complication watchmaking. The result is a watch that carries one of horology's most complex complications while feeling feather-light on the wrist.

The salmon dial, a tone that references the warmth of rose gold in the most nuanced terms, displays the perpetual calendar's suite of information — day, date, month, and moon phase — with the clarity and elegance that has defined AP's integrated calendar layout for decades. Luminous baton hands on titanium stems sweep across the guilloché surface, and the transparent sapphire caseback reveals the Calibre 5134's intricate cam-and-lever perpetual calendar mechanism — a movement that requires no manual correction until 2100.

The integrated titanium bracelet, sharing the same case metal, presents alternating brushed and polished surface treatments that honour the Royal Oak tradition while introducing a contemporary grey-metal restraint. The AP folding clasp closes with a satisfying precision. Limited production and the rarity of titanium-cased perpetual calendar Royal Oaks makes 26615TI a reference that serious collectors pursue with particular intent. Offered here with box and papers, this is a horological landmark dressed in the most forward-looking of metals.
