Adjusting the Strap
The Oozoo C11510 watch comes with a leather strap. To adjust the fit, simply use the buckle to select the appropriate hole that provides a comfortable and secure fit on your wrist. Ensure the strap is not too tight to avoid discomfort, nor too loose to prevent the watch from moving excessively.

Maintenance
Cleaning Your Watch
To maintain the appearance of your watch, wipe the case and crystal with a soft, dry cloth regularly. For the leather strap, avoid excessive moisture and harsh chemicals.
Water Resistance
This watch is water resistant up to 2 bar (20 meters / 66 feet). This rating means the watch is suitable for splashes, rain, and incidental contact with water. It is not suitable for showering, swimming, diving, or any activities involving submersion in water. Always ensure the crown is fully pushed in to maintain water resistance.
Strap Care
The leather strap is durable but can be affected by moisture, sweat, and direct sunlight. To prolong its life, avoid prolonged exposure to water and direct heat. If the strap becomes wet, allow it to air dry naturally, away from direct heat sources.
Battery Replacement
When the watch stops running, it indicates that the battery needs to be replaced. It is highly recommended to have the battery replaced by an authorized service center or a professional watchmaker to ensure the watch's integrity and water resistance are maintained.
Troubleshooting
- Watch Not Running: Check if the crown is fully pushed in. If it is, the battery may need replacement.
- Inaccurate Time: Ensure the crown is fully pushed in. If the time remains inaccurate, the watch may require servicing.
- Condensation Under Crystal: This indicates a loss of water resistance. Immediately take the watch to a professional for inspection and repair to prevent further damage.
- Chronograph Hands Not Resetting to Zero: If the chronograph hands do not return to their zero position after pressing the reset pusher, the watch may need adjustment by a professional.
