Compatibility:
This is a standalone digital watch and does not require compatibility with smartphones or other devices for its core functions. It operates independently.
Care:
- Cleaning: Clean the resin band and case with a soft, damp cloth. Avoid using solvents or abrasive cleaners, which can damage the resin. For tougher grime, use mild soap and water, then rinse thoroughly and dry.
- Water Resistance: While rated for 200m water resistance, avoid operating buttons underwater. For prolonged water exposure or diving, ensure the case back is securely fastened and gaskets are in good condition. Have seals checked periodically by a professional if the watch is frequently exposed to harsh water conditions.
- Battery: The watch is powered by a long-lasting battery. Replacement should be done by a qualified watch technician to maintain water resistance.
