How to use (For Cal. 9R01)

This watch features a time difference adjustment function. The hour hand can be easily adjusted in one-hour increments without stopping the minute and seconds hands. This function is convenient especially when traveling abroad.

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 use the independent hour-hand adjustment function

  1. Pull out the crown to the first click.

  2. The seconds hand keeps moving.

  3. Turn the crown counterclockwise to advance the hour hand. The hour hand moves in one-hour increments.

  2. Turn the crown 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 second click.

  4. The seconds hand will stop moving when the crown is pulled out to the second 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.
