Radial ball differential
The Dara ball differential is based on a compact modular design in which the two inputs of the differential gear are connected to the teeth of the barrel-drum and to those of the ratchet wheel. The output from the differential is linked to the power reserve indicator.
Patent number: EP1995649A2

Traditional ball differential systems in watchmaking generally need a watchmaker to make the sensitive friction adjustment when assembling the movement.
Our engineers have designed a preset independent module offering precision and reliability to implement the power reserve indicator function.
