In horological terms, a hand is a piece of metal composed of two or several parts, which main function is to give time indication of the movement to the dial marks. The hands are an integral part of the aesthetic of the watch, according to the current watch marketing: “Corporate Identity” of the watch brand. Thereby, every hand’s design isn’t only specific to the calibre and the model’s watch by its dimension and technical tolerance, but also by its aesthetical finishes, in harmony with the dial and case’ style watch, etc. Every RESERVOIR collection has its own universe, a hand is dedicated to every one of them. The leaf-shaped hand for the Supercharged collection, the blued steel hand for the Tiefenmesser, the “sword” hand for the Airfight collection and “baton” hand for the GT Tour collection. The choice of the hand is essential: it defines the watch’s character and aestheticism.
