4. Maintenance
4.1 Cleaning Your Watch
- Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and dirt.
- For the stainless steel strap, a slightly damp cloth can be used, followed by immediate drying.
- Avoid using chemical cleaners, solvents, or abrasive materials, as these can damage the watch's finish and seals.
4.2 Water Resistance Guidelines (5ATM / 50 Meters)
- Your watch is resistant to splashes, rain, and brief immersion in water (e.g., washing hands, showering).
- Do NOT operate buttons or the crown while the watch is wet or submerged.
- Avoid exposing the watch to hot water, steam (e.g., hot showers, saunas), or extreme temperature changes, as this can compromise the water-resistant seals.
- Not suitable for diving or high-impact water sports.
4.3 Battery Replacement
The watch uses a Japanese battery. When the display dims or the watch stops functioning, it may be time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and prevent damage to the movement.
4.4 General Care
- Avoid exposing the watch to strong magnetic fields, as this can affect the accuracy of the quartz movement.
- Protect the watch from strong impacts or drops.
- Store the watch in a cool, dry place when not in use.
5. Troubleshooting
- Watch Not Running / Digital Display Blank:
- Check if the battery needs replacement. If the watch is new, ensure any plastic battery tab has been removed.
- If the watch has been exposed to water, ensure it is completely dry. - Analog Hands Not Moving:
- Ensure the crown is pushed all the way in.
- If the issue persists, the battery may need replacement or there might be a mechanical issue. - Digital Display Incorrect:
- Re-set the digital time and date following the instructions in Section 3.2. - Luminous Display / Hands Not Glowing:
- The luminous material on the hands and markers needs to be charged by light. Expose the watch to bright light (natural or artificial) for a few minutes to activate the glow. The glow will fade over time in darkness. - Water Inside the Watch:
- If you notice condensation or water droplets inside the watch, stop using it immediately and take it to a professional watch repair service. This indicates a compromised water seal.
