903 H4

For many watch lovers, the use of a hand-wound movement represents the purest form of a mechanical watch. No rotor impedes the view of the movement. Regularly winding becomes a personal ritual.  For those who are fascinated by a traditional hand-wound movement, there is a special series of our classic 903 navigation chronograph. This navigation chronograph has everything you need for precise orientation in time and space. The minute counter and the small second counter are at 3 and 9 o'clock respectively, while the hour counter is positioned at 6 o'clock. The second stopwatch hand at the center of the timepiece has a red triangular tip.  The design of the classic Lemania movement permits the integration of an additional complication in the Sinn 903 H4: the moon phase display is positioned in the circular field for the hand date at 12 o'clock. Thus a fourth time display completes the selection on the inner surface of the dial, making this model the most complex version of our navigation chronograph.
