ROSE GOLD

Watches featuring a « sonnerie » complication indicate the hour and quarters by means of hammers hitting bells or gongs which are tuned to different pitches. Chimes were originally made as a means of telling the time in the dark.

The tourbillon system was made to compensate the Earth’s gravitational force by mounting the escapement in a revolving cage. It gives the watch a better accuracy. This complication is known as one of the most difficult to make.
