Water Resistance
Watches are classified by water resistance levels (I to V). Refer to the table below to understand usage guidelines.
| Level | Marking on Case | Splashes, Rain, etc. | Washing Car, etc. | Snorkeling, Diving | Scuba Diving |
|---|---|---|---|---|---|
| I | (No Marking) | Yes | No | No | No |

| V | 200 M WATER RESISTANT | Yes | Yes | Yes | Yes |
| VI | 300 M WATER RESISTANT | Yes | Yes | Yes | Yes |
Notes:
- Level I watches are not water-resistant. Avoid all contact with water.
- Do not press buttons underwater.
- If the watch comes into contact with salt water, rinse it thoroughly with fresh water and dry it.
- Level V watches can be used for scuba diving (excluding depths requiring helium-oxygen gas mixtures).
- Some water-resistant watches have leather straps. Do not wear these models while swimming or engaging in activities where the strap may get wet.
Watch Care
- Never attempt to open the case or remove the back cover.
- The gasket, which protects the watch from water and dust, should be replaced every 2-3 years.
- If moisture enters the watch, have it checked immediately by an authorized CASIO dealer.
- Avoid exposing the watch to extreme high or low temperatures.
- While designed for normal use, avoid rough handling and dropping the watch.
- Do not overtighten the strap. A finger should fit between your wrist and the strap.
- Clean the watch and strap with a dry, soft cloth, or a soft cloth dampened with a mild solution of neutral detergent and water. Never use volatile substances like gasoline, solvents, aerosol cleaners, etc.
- When not in use, store the watch in a dry place.
- Avoid contact with gasoline, cleaning solvents, aerosol sprays, adhesives, paint, etc. Chemical reactions can damage gaskets, the case, and the watch's finish.
- Some models feature silk-screened designs on the strap. Clean these carefully and avoid rubbing vigorously to prevent damage to the designs.
- For watches with polymer straps: A white powdery substance may appear on the strap. This substance is harmless and can be easily removed by wiping with a cloth.

- Press the 'C' button to cycle through the digits to be set: Seconds, Hours, Minutes, Day of Week, Month, Day, Year.
- Use the 'D' button to increase a flashing digit or the 'B' button to decrease it. Holding either button allows for faster adjustment.
- To reset seconds to '00', press 'D' when seconds are flashing. If seconds are between 30-59, minutes will increment when seconds reset. If seconds are 00-29, minutes remain unchanged.
- To switch between 12-hour (AM/PM) and 24-hour formats, press 'D' when the hour digits are flashing.
- After setting all values, press 'A' twice to return to the normal timekeeping display.
Caution: The date can be set from January 1, 1995, to December 31, 2039. If no buttons are pressed for several minutes during setting, the display will stop flashing and return to the normal timekeeping mode.

- After selecting a date, the watch will calculate and display the moon transit times.
Tide Graph Mode
Properly set current time, coordinates, and tidal interval before using this mode. The watch generates a tide graph based on this information.
Calculating Tidal Interval:
- Find the time of high tide for your desired location.
- Use the watch to find the moon's upper transit time just before the high tide.
- Subtract the moon's transit time from the high tide time to get the tidal interval.
Setting Tidal Interval:
