Maintenance and Care
To ensure the longevity and proper functioning of your SYNOKE watch, follow these guidelines:
- Cleaning: Wipe the watch with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth and mild soap, then dry thoroughly.
- Battery Replacement: The watch uses a 3V Lithium Battery. When the display dims or functions become erratic, it's time to replace the battery. It is recommended to have this done by a professional to ensure water resistance is maintained.
- Water Resistance (3BAR / 30M):

Figure 6: Water Resistance Usage Range and Important Notices. The watch is water resistant to 30 meters (3BAR), suitable for daily use, hand washing, rain, and accidental splashes. It is NOT suitable for showering with hot water, swimming, diving, or prolonged submersion. Avoid pressing buttons underwater.
Important Notices:
- Do not approach magnets such as speakers, televisions, radios, etc., as it may affect product performance.
- Do not approach solvents, mercury, cosmetic sprays, cleaners, adhesives, paints, sea water, and other substances to avoid damage caused by chemical reactions.
- Avoid hot water and steam.
- In some cases, water vapor inside the watch is caused by temperature differences, which is normal. Putting the watch on a desiccant will help the vapor disappear.
- Shock Resistance: While designed to be shock resistant, avoid excessive impact to prevent damage.
