Ulysse Nardin Ulysse I Chronometer

The Ulysse I is equipped with the same type of power reserve indicator used in Ulysse Nardin pocket watches produced in 1912. The power reserve is unique in that both the small hand and the underlying disk turn. When the movement is wound (up), either manually or automatically by the movements of the wrist when the watch is being worn, the small disk below the figure 12 turns counter-clockwise until the largest segment of the scale reaches the power reserve hand.As the movement unwinds (down) when the watch is not worn, the power reserve hand turns counter-clockwise down on the scale shown on the disk until it reaches the smallest segment of the scale. On standard power reserve indicators only the hand moves down on a printed scale on the dial. The self-winding movement is fully wound when the hand points to the largest segment on the disk. The movement has a power reserve of approximately 42 hours. Chronometer Certificate C.O.S.C.
