F. Adjusting (synchronizing) the chrono hands to zero position
One or several chrono hands are not in their correct zero position and have to be adjusted (e.g. after a change of a battery or gone through
an area with strong magnetic field).
1. Pull out the crown to position C.2.
2. Press down the pusher A and B simultaneously until the centre second counter hand rotates. The corrective mode is now activated.
3. Press down the pusher A repeatedly until the center second counter hand is at zero. Then press down pusher B once. Now the 1/10th
second counter is ready to be adjusted.
4. Press down the pusher A repeatedly until the 1/10th second counter hand is at zero. Then press down pusher B once again, now the
minute counter is ready to be adjusted.
5. Press down the pusher A repeatedly until the minute counter hand is at zero. This will complete the synchronization process.
6. Now push back the crown to position C.0.
