Description

Audemars Piguet reveals the Royal Oak Perpetual Calendar Openworked “150th Anniversary” limited edition, reflecting the brand’s rich legacy in design, material and technical exploration. This timepiece is the last to be equipped with Calibre 5135 and gracefully bids farewell to the movement that has powered the Manufacture’s 41 mm openworked selfwinding perpetual calendar wristwatches.

Enhancing its timeless appeal, this model’s high-tech combination of titanium and Bulk Metallic Glass (BMG) on the case and bracelet creates a sophisticated contrast with the dial’s vintage aesthetic inspired by a pocket watch exhibited in the Musée Atelier Audemars Piguet (reference 25729). This elegant limited edition of 150 pieces is adorned with design codes developed specifically for the anniversary.

Supplied by the brand to the GPHG for its entry.
