Excalibur

Chronograph

The chronograph is an extremely complex mechanism that measures short time intervals. At ROGER DUBUIS, chronograph movements are authentic works of art that demonstrate unique architecture. Like the most sophisticated haute horlogerie chronographs, they are equipped with a column wheel to control the start, stop and restart functions.
