Minute Repeater Tourbillon with Gold Bridges

Girard-Perregaux 2015

ref. 99820-52-000-BA6A
Men's

Girard-Perregaux has entirely rethought the minute repeater movement in terms of both its construction and its operation, so as to reveal the striking mechanism on the dial side, alongside its famous Tourbillon with Gold Bridges. The complex and original solution adopted is pleasing on both visual and auditory levels. The watch chimes loudly and clearly, even when on the wrist. To ensure perfect harmony, the hammers feature a design inspired by the gold bridges. The master watchmaker devotes around 270 hours of work to assembling and adjusting this magnificent mechanism housed in a pink gold case with a domed sapphire back that serves as a sounding box.
