The Royal Oak Concept Flying Tourbillon is particularly adorned with 208 sapphires in shades of blue, the baguette-cut stones being distributed throughout the watch’s case made entirely of 18-carat rose gold. Water-resistant to 20 metres, the Audemars Piguet Royal Oak Concept Flying Tourbillon measures 38.5 mm in diameter and 11.6 mm in height. The blue bracelet perfectly matches the case and dial, and is made of high-quality alligator leather and fine hand-stitching, with a folding clasp in 18-carat rose gold set with a baguette-cut sapphire.
