How to use (For Cal. 9R02)

How to wind the mainspring

When starting to use a stopped watch, you need to turn the crown to wind the mainspring. To wind the mainspring, turn the crown at the normal position clockwise (12 o’clock direction) slowly. If you turn the crown counterclockwise (6 o’clock direction), it will turn free.

Under a low-temperature condition (below 0°C), always keep at least one-sixth of the watch power shown by the power reserve indicator.

How to set the time

  1. Pull out the crown to the first click when the seconds hand is at the 12 o’clock position. The seconds hand stops on the spot.

  2. Turn the crown to the left (6 o’clock direction) to set the hour and minute hands to the desired time.

  3. Complete the procedure by pushing the crown back into the normal position in accordance with a time signal.

Tips for more accurate time setting

To ensure effective operation of the Spring Drive mechanism, observe the following instructions when you set the time.

  1. Before setting the time, make sure to wind the mainspring sufficiently.

  2. (Ensure that the power reserve indicator is showing a full-wound state.)

  3. When starting to use a watch after it stops, wind the mainspring sufficiently. To set the time after that, wait for approximately 30 seconds after the seconds hand starts moving, then pull the crown out to the first click.

  4. The seconds hand will stop moving when the crown is pulled out to the first click. Do not stop the movement of the seconds hand for longer than 30 minutes. If the stoppage of the seconds hand movement exceeds 30 minutes, push the crown back in, and wait for approximately 30 seconds after the seconds hand restarts moving, and then set the time.
