The Audemars Piguet Royal Oak Offshore Selfwinding Music Edition (Ref. 77601BC.YY.D343CA.01) is a 37mm white gold timepiece that seamlessly blends avant-garde gemsetting with a design inspired by music. The blue aventurine dial features pioneering harmony-cut coloured gemstones arranged in a VU meter pattern, echoing the gemset bezel. A blue textured interchangeable rubber strap adds a refined touch.
