>>LOUIS MOINET-Vertalis Tourbillon

Technique of the Tourbillon
Representing the very principle of the tourbillon, the fact of fitting the entire escapement within a mobile carriage services to cancel out the effects of gravity and to improve rating precision. Thus united inside their mobile carriage, the balance and its spring, the lever wheel and the lever perform a complete rotation every sixty seconds. Crafting a tourbillon is still one of the most difficult exercises in the field of Haute Horlogerie.

VERTALIS Tourbillon by Louis Moinet
As its name implies, the difference here is all about verticality: VERTALIS intensifies the magic of the tourbillon by connecting its carriage to the barrel by means of a hand-drawn and bevelled vertical bar. To add to the fascinating vision of the tourbillon carriage in motion, VERTALIS offers an openworked version of the barrel. The latter’s cover performs an average rotation in 6 hours and enables one to keep visual check on the power reserve according to the state of wind of the barrel spring.

Louis Moinet displays its determination to combine aesthetic and technical aspects, particularly through the vertical bar that showcases the technology of the watch, while extending over onto the case. This original and modern way of uniting displays, technology and casing is directly inspired by the historical world of Louis Moinet, and especially by some of the drawings published in his famous Traité d’Horlogerie in 1848.

Crafted in a limited edition of 12, the exclusive VERTALIS tourbillon movement is hand-wound and beats at a cadence of 21,600 vibrations per hour. One particularly striking technical characteristic is the spectacular visibility of the winding mechanism through the case-back. The “octopus” spring plays three roles by acting as pull-out piece spring, lever spring and click spring.
VERTALIS is presented in an exceptional new case composed of 50 different parts. It highlights the union of two gold colours: the warm shade of 5N rose gold, and the white gold that accentuates and pursues the geometrical effect of the vertical bar. The dial features “Côtes du Jura”® against a black background enhanced with rose gold hour-markers. The case is also equipped with the Louis Moinet crown guard, incorporating the stem in such a way as to enable easy replacement if required (patent pending).
