3. Care and Maintenance
3.1 Cleaning Your Watch
To maintain the appearance and longevity of your NIXON Siren watch, clean it regularly with a soft, damp cloth. For silicone bands, mild soap and water can be used. Avoid harsh chemicals or abrasive materials that could damage the watch.
3.2 Water Resistance
The NIXON Siren watch is water-resistant up to 100 meters (10 ATM). This makes it suitable for swimming, surfing, and snorkeling. However, it is not recommended for scuba diving. Ensure all buttons are not pressed while the watch is submerged in water to prevent water ingress.
3.3 Battery Replacement
The watch is powered by a product-specific battery (included). When the battery needs replacement, it is recommended to take the watch to an authorized NIXON service center or a professional watch repair shop to ensure proper sealing and maintain water resistance.

When not in use, store your watch in a cool, dry place away from direct sunlight and extreme temperatures. Avoid exposing the watch to strong magnetic fields.
