The Vertalis intensifies the magic of the tourbillon by connecting its carriage to the barrel by means of a hand-drawn and beveled vertical bar. To add to the fascinating vision of the tourbillon carriage in motion, this watch offers an openworked version of the barrel. The latter’s cover performs an average rotation in six 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.
