5.2. Water Resistance
Your Pagani Design PD-1644 watch has a water resistance rating of 100 meters (10 ATM). This means it is suitable for:
- Daily use, including hand washing and splashes.
- Swimming in shallow water.
- Short showers.
It is not suitable for:
- Diving or snorkeling.
- Hot water activities (e.g., hot tubs, saunas), as steam can penetrate seals.
- Operating the crown or pushers while the watch is wet or submerged.
Prolonged contact with water may reduce the lifespan of the watch.
6. Maintenance
6.1. Cleaning
To maintain the appearance and hygiene of your watch, regular cleaning is recommended. Use a soft, microfiber cleaning cloth to gently wipe the watch case and stainless steel bracelet. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying.
6.2. Battery Replacement
As a quartz watch, the PD-1644 is powered by a battery. When the battery runs low, the second hand may start to move in two-second intervals (End-of-Life indicator). It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and water resistance are maintained.
6.3. Storage
When not in use, store your watch in a cool, dry place, away from direct sunlight, extreme temperatures, and strong magnetic fields. The original gift box provides excellent protection.
7. Troubleshooting
If you encounter any issues with your watch, please refer to the following common problems and solutions:
- Watch Not Running: Check if the crown is pushed in completely. If it is, the battery may need replacement.
- Incorrect Time/Date: Refer to Section 4 for instructions on setting the time and date.
- Chronograph Hands Not Resetting to Zero: Refer to Section 4.3 for chronograph hand zero reset instructions.
- Condensation Under Crystal: This may indicate a loss of water resistance. Avoid further water exposure and seek professional service immediately.
