8. Water Resistance Guidelines

Image: The TEKMAGIC W17-Y watch partially submerged in water, with bubbles around it, and text indicating "100m Underwater Waterproof" and "Diving grade waterproof standard."
The TEKMAGIC W17-Y watch is rated for 10 ATM (100 meters / 330 feet) water resistance, suitable for swimming, snorkeling, and recreational diving. Important: Do not press any buttons while the watch is submerged in water. Pressing buttons underwater can compromise the water resistance seals and lead to water ingress. Ensure the crown is fully pushed in before any water exposure.
Maintenance
1. Cleaning Your Watch
Wipe the watch regularly with a soft, damp cloth to remove dirt and sweat. For stubborn grime, a mild soap solution can be used, followed by rinsing with fresh water and thorough drying. Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish or seals.
2. Battery Replacement
The watch uses a CR2025 button cell battery, which typically lasts 1.5 to 2 years. If the display becomes dim or the watch stops functioning, it's time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure the water resistance seal is properly re-seated. If replacing yourself:
- Carefully remove the back cover of the watch using a suitable watch case opener.
- Gently remove the old CR2025 battery.
- Insert a new CR2025 battery, ensuring correct polarity (+ side up).
- Carefully replace the back cover, ensuring the gasket is properly seated to maintain water resistance. Tighten screws evenly.
Warning: Improper battery replacement can compromise the watch's water resistance.
3. Water Resistance Care
To maintain the watch's water resistance, ensure the crown is always fully pushed in. Avoid exposing the watch to extreme temperature changes (e.g., hot showers followed by cold water), as this can cause seals to expand and contract, potentially leading to water ingress. Do not press buttons while the watch is wet or submerged.
Troubleshooting
- Watch not working or display dim: The battery may be low or depleted. Replace the CR2025 battery as per the "Maintenance" section.
- Water inside the watch: If water droplets appear inside the watch, immediately stop using it and seek professional service. This indicates a compromised water resistance seal, likely due to pressing buttons underwater or improper sealing after battery replacement.
- Time inaccuracy: If the watch is consistently losing or gaining time, the battery may be weak, or the movement may require service. Replace the battery first. If the issue persists, contact support.
- Buttons unresponsive: Ensure the watch is not in a locked mode (if applicable, though not a feature mentioned for this model). If buttons remain unresponsive, a reset might be needed (often by removing and reinserting the battery), or the watch may require service.
