Operating the Luminous Feature

The hands and hour markers of your Gosasa watch are coated with a luminous material. This material absorbs light energy from natural or artificial light sources and then emits a glow in dark conditions.

• For optimal glow, expose the watch to a bright light source for a few minutes before entering a dark environment.
• The intensity and duration of the glow depend on the amount and duration of light absorbed.

Maintenance and Care

Water Resistance (30M / 3 ATM):

• Your watch is water-resistant to 30 meters (3 ATM). This means it is suitable for daily use, such as splashes, rain, and hand washing.
• It is not suitable for swimming, showering, diving, or any water sports where it will be fully submerged for extended periods.
• Do not operate the crown or pushers when the watch is wet or submerged in water.

Cleaning:

• Wipe the watch case and crystal with a soft, dry cloth.
• For the silicone strap, clean with mild soap and water, then rinse thoroughly and dry completely.
• Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish.

Battery Replacement:

The quartz movement is powered by a battery. When the watch stops or the timekeeping becomes erratic, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and water resistance.

Storage:

Store your watch in a dry place, away from direct sunlight, extreme temperatures, and strong magnetic fields, which can affect the accuracy of the quartz movement.

Troubleshooting

• Watch not running: Ensure the crown is fully pushed into position 0. If the watch still does not run, the battery may need to be replaced.
• Time or Date is incorrect: Follow the "Setting the Time" and "Setting the Date" instructions in the Setup section to adjust.
• Luminous feature not glowing: Expose the watch to a bright light source for a longer period to allow the luminous material to absorb sufficient light energy.
• Condensation inside the watch: This indicates a loss of water resistance. Immediately take the watch to a professional for inspection and repair to prevent further damage. Water damage due to exceeding the specified water resistance limits is typically not covered under warranty.
