Girard-Perregaux Rose Gold DoubleTri-Axial Tourbillon Watch Girard-Perregaux Swiss watches by wholesalewatches - December 17, 20150 Girard-Perregaux has an ultra-luxury Tri-Axial Tourbillon, the watch is limited edition with double axis tourbillon in line-up. The Tri-Axial Tourbillon is somewhat late to the multi-axis tourbillon segment, with watchmakers like Jaeger-LeCoultre and Greubel Forsey having got there several years ago. Nonetheless, it is nothing to sniff at, with the GP09300 calibre comprising 317 parts – the tourbillon alone is made of 140 components. Sitting under a domed sapphire bubble, the triple axis tourbillon has at its innermost axis a one minute with the traditional lyre-shaped cage. That in turn is mounted on a second cage that makes one revolution every 30 seconds.To the right of the tourbillon is the dial for the time, decorated with a clous de Paris, or hobnail, guilloche, and below that the indicator for the 52 hour power reserve.Behind the sapphire case back the movement is visible, with a frosted finish on the three-quarter plate, over which are two gold bridges in the signature arrow shape of the brand.
