Academia Tourbillon Force Constante à Chaîne

DeWitt has enhanced its legendary constant force tourbillon with a system that relays energy to its associated power reserve indicator. Rotating the crown when winding the barrel-spring drives a miniature chain, which uses an intermediate wheel to activate the power reserve indicator sliding on a worm screw. Three years after developing an ingenious patented regulating system – three extra wheels transmitting impulses of identical force to the tourbillon, whatever the barrel’s degree of tension – DeWitt has now taken innovation to even greater heights.
