Audemars Piguet Royal Oak Frosted Gold Double Balance Wheel Open-worked 37mm, Set with Rainbow Coloured Sapphires

This Royal Oak timepiece boasts a shimmering 18-carat Frosted Gold case and the bezel featuring 32 baguette-cut “rainbow coloured” sapphires (2.24 carats), all individually cut. It’s a breath-taking setting for the rhodium-toned open-worked dial and golden double balance wheel mechanism, visible on both sides of the watch.

This Audemars Piguet patented innovation involves a complex fabrication procedure that improves the watch’s precision and stability. By incorporating two balance wheels and two hairsprings that are assembled on the same axis, the system oscillates in perfect synchronize.

The Frosted Gold case and bracelet are set off by the “rainbow-coloured” sapphires decorating the bezel. The golden balance wheel is visible on both sides of the watch.
