3. Operating Your Watch
Water Resistance:
Your Casio MRW-210H watch is water resistant to 100 meters (10 BAR). This means it is suitable for swimming, snorkeling, and showering. However, it is not suitable for scuba diving. Do not operate the crown or buttons while the watch is wet or submerged.
Using the Rotary Bezel:
The watch features a bidirectional rotary bezel. This bezel can be rotated in either direction. It is commonly used to mark elapsed time. Align the bezel's triangular marker with the minute hand at the start of an event to track the duration.
4. Care and Maintenance
Battery Replacement:
The watch is powered by a Lithium Metal battery with an approximate 3-year life. When the watch stops or the second hand moves erratically, it is time to replace the battery. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
General Care:
- Cleaning: Wipe the watch and band with a soft, dry cloth to remove dirt and moisture. For the resin band, you can use a mild soap solution and rinse thoroughly.
- Temperature: Avoid exposing the watch to extreme temperatures, direct sunlight for prolonged periods, or strong magnetic fields.
- Chemicals: Keep the watch away from gasoline, cleaning solvents, aerosol sprays, adhesives, paints, etc., as these can cause discoloration or damage to the resin components.
5. Troubleshooting
Incorrect Day/Date Display:
If the day of the week displays an unfamiliar language or the date changes at noon instead of midnight, it indicates an incorrect AM/PM setting or day language selection. Refer to the "Setting the Date and Day of the Week" section (Section 2) and ensure you rotate the crown sufficiently to cycle through all language options and set the correct AM/PM for the time.
