Operating the Watch

  • Reset: While the chronograph is stopped, press pusher (C) to reset all chronograph hands to zero.

2. Indiglo Night-Light

The Indiglo night-light illuminates the watch dial for visibility in low-light conditions.

  • Press and hold the crown (B) to activate the Indiglo night-light. It will remain lit as long as the crown is pressed.

3. Water Resistance

This watch is water-resistant to 100 meters (330 feet).

  • Suitable for snorkeling, swimming, and showering.
  • Not suitable for scuba diving.
  • Do not operate the crown or pushers while the watch is wet or submerged to prevent water intrusion.

Maintenance

1. Battery Replacement

The watch uses one Lithium Metal battery (included). When the watch stops running, the battery may need replacement. It is recommended to have battery replacement performed by a qualified watch technician to ensure proper sealing and maintain water resistance.

2. Cleaning

To clean your watch:

  • Wipe the case and crystal with a soft, damp cloth.
  • For the nylon strap, a mild soap solution and soft brush can be used, followed by thorough rinsing and air drying.
  • Avoid using harsh chemicals or abrasive materials.

3. Storage

When not wearing your watch, store it in a cool, dry place away from direct sunlight and extreme temperatures.

Troubleshooting

  • Watch Not Running: Check if the crown is fully pushed in (position 1). If it is, the battery may need replacement.
  • Date Not Changing: Ensure the time is set correctly, passing midnight will advance the date. If using the Quick Date function, ensure the crown is in position 2.
  • Chronograph Malfunction: If chronograph hands do not reset to zero or operate incorrectly, try resetting the watch by pulling the crown to position 3, waiting a few seconds, and then pushing it back in. If the issue persists, professional service may be required.
