Abstract

The watch contains two barrels (2, 3) whose springs are mounted in series. The output torque from the assembly is equal to that from one of the barrel springs and the output angular speed of the assembly is equal to the sum of the angular speeds of the two barrels. This speed is around twice that of a barrel in a conventional watch, that is to say greater than 0.3 of a revolution per hour. <IMAGE>
