Manual & Self-winding watch

Power reserve (continued)

If the watch is not worn, or during periods of low activity, the power reserve indicator hand progressively moves anti-clockwise.

If the power reserve indicator hand is pointing to below 1/4, this means that the watch’s power reserve is less than 10 hours. In this case, the watch should be worn or wound by hand to prevent it stopping.

During manual winding (crown in position 1) or when worn (self-winding), the power reserve indicator hand moves clockwise.

CALIBRES 2005 (fig. II) • 2200, 2201, 2202 (fig. VIIIbis) • 2403 (fig. VIII)

The crown has 2 positions:

1.Normal position (wearing position): when pushed into the case, the crown ensures that the watch is water-resistant. Occasional winding: if the watch has not been worn for 44 hours or more, wind it up with the crown in position 1.

CALIBRE 2201 (Manual-winding)

Winding: turn the crown forwards until it stops.

2.Time setting: hours – minutes. Pull the crown out to position 2. Turn the crown forwards or backwards. Push the crown back to position 1.

For calibres 2200, 2202 and 2403: synchronise the seconds by pushing the crown back to position 1 to coincide with a given time signal.
