2. Setting the Time
- Pull the crown out to the time setting position.
- Rotate the crown to set the hour and minute hands to the correct time.
- Push the crown back into the normal position to start the watch.

Operating Instructions
Timekeeping
This watch features a 3-hand movement, displaying hours, minutes, and seconds. Once the time is set and the watch is sufficiently charged, it will accurately keep time. The Eco-Drive movement continuously charges when exposed to light, ensuring consistent operation.
Maintenance
Cleaning
Wipe the watch case and bracelet periodically with a soft, dry cloth to remove dirt and moisture. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Avoid using harsh chemicals or abrasive materials.
Water Resistance (50 Meters / 5 ATM)
Your watch is water resistant to 50 meters (5 ATM). This means it is suitable for short periods of recreational swimming, showering, and general daily use. It is not suitable for diving, snorkeling, or prolonged water immersion. Always ensure the crown is fully pushed in before any contact with water.

To maintain optimal performance, ensure your watch is regularly exposed to light. Avoid storing it in dark places for extended periods. The watch contains a rechargeable Lithium Ion battery that is continuously charged by the Eco-Drive system.
Troubleshooting
Watch Has Stopped
If the watch hands stop moving, it indicates insufficient charge. Expose the watch to bright light for several hours to recharge it. The watch should resume normal operation once adequately charged.
