Dual complications, Master Grande Tradition Tourbillon à Quantième perpétuel

Dual complications, Master Grande Tradition Tourbillon à Quantième perpétuel

The tourbillon in the Master Grande Tradition Tourbillon with perpetual calendar attracts attention for its two-level construction. The pace of the two opposing rhythms enlivens this timepiece: a balance beating at eight vibrations per second and the slow rotation of the perpetual calendar some of the wheels of which will take 100 years to make a complete revolution.

A unique interplay of contrasts between the sides, the top, the horns and the caseback. The rounded polished bezel underscores the watchmaking heritage. The dial alternates between velvety soft surfaces and a Clous de Paris engine-turned pattern. The oscillating mass of this selfwinding calibre in 22-carat gold is decorated with a Clous de Paris pattern while the unique tourbillon bridge is decorated by hand.
