Maitres du temps- Chapter One

The ease of both reading and adjusting Chapter One's many indications disguises the fact that this is a world-first combination of complications crafted from 558 components.
No other wristwatch has featured a tourbillon with mono-pusher column wheel chronograph, retrograde date, and retrograde GMT, as well as moon phase and day of the week on their own rolling bars.
Long, flowing compound curves traverse the case while scintillating laser-pierced moon and stars on the outer roller of the moon phase indicator add to its stellar elegance.

Dewitt- Academia Tourbillon Force Constante

DeWitt has inbuilt 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.
