Before Using the Watch for the First Time

• Depending on your watch model, there may be a spacer installed at the factory around the crown. If your watch has a spacer, you should remove the spacer before using the watch.
• After removing the spacer, use the procedures in “Crown Operations” and “To adjust the time setting” to set up the watch for use.

Crown Operations

Some water-resistant models (10BAR, 20BAR) have a screw in crown. When you need to perform a crown operation, rotate it towards you to unscrew it. Then pull the crown out. Avoid applying undue force when pulling. The watch loses its water resistance while the crown is unscrewed. After performing a crown operation, fully screw the crown back in.

If your watch has a rotary bezel….

You can rotate the bezel to align its mark with the minute hand. Then you will be able to tell how much time has elapsed since aligning the mark.

Solar Charging

A solar panel generates electrical power that charges a built-in (secondary) battery. The entire face is a solar panel, so power is generated when the face is exposed to light. Keep the watch exposed to light as much as possible.
Charging the Battery
When you are not wearing the watch, leave it where it is exposed to light. For stable operation, expose the watch to at least a half day of light per month.

When wearing the watch, try to keep your clothing from blocking its face (solar panel). Charging efficiency is reduced significantly even if the face is blocked only partially.

Caution!

• The case of the watch may become quite hot when charging. Guard against burn injury after charging.
• Avoid charging in the following locations, and anywhere else where the watch may become very hot.
  • On the dashboard of an automobile parked in the sun
  • Close to an incandescent light source or other sources of heat.
  • Locations exposed to direct sunlight for long periods.

 Battery Indicator

The battery level/stopwatch minute hand normally indicates the approximate amount of remaining operating time of the battery will provide.

• Battery operating time is not indicated while the stopwatch is in use.
• After resetting the stopwatch to all zeros, the stopwatch minute hand will go back to indicating battery operating time if you press or if you do not perform any operation for 60 seconds.

Approximate Battery Operating Time

Low Charge and Dead Battery Conditions

An alert operation is performed when the battery charge goes low.
