1946 – The exacomatic pivoting patented
Back to Timeline
Vulcain patented the innovative Exactomatic system, which was used in the famous Cricket caliber in 1946.
The purpose of the Exactomatic principle is to equalise the friction on the balance-wheel axis in all positions by modifying the Incabloc endstones. This provides a more regular amplitude. So the Exactomatic principle provides greater accuracy and better regularity in the operation of the watch while, it is being worn.
Vulcain is currently equipping other of the movements with the Exactomatic System.
