5. Maintenance
5.1. Water Resistance
Your PINDOWS Digital Sports Watch is designed with 50-meter (5ATM) water resistance. This means it is suitable for daily use, showering, swimming in shallow water, and light rain exposure. However, it is not suitable for diving, snorkeling, or high-pressure water activities.
- Do not press any buttons while the watch is submerged in water.
- Avoid exposing the watch to hot water or steam, as this can compromise the water-resistant seals.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.

5.2. Cleaning
To clean your watch, wipe it with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, followed by rinsing with clean water and thorough drying. Avoid using harsh chemicals or abrasive materials, which can damage the watch's finish or components.
5.3. Battery Replacement
The watch is powered by a CR2032 battery. When the display becomes dim or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and water resistance are maintained.
