Important Information
Please read this important information before proceeding.
Battery
If the display becomes dim or shows no illumination, replace the battery at an authorized CASIO dealer or distributor. The battery included with your watch is a test battery, and its service life may be shorter than the standard battery.
Water Resistance
Watches are classified by water resistance level (from Level I to Level V). Refer to the table below to determine the rules for using your watch.
| Marking on Case | Splashes, Rain, Washing | Swimming, Washing | Skin Diving, Scuba Diving | Diving with Helium-Oxygen Mixture |
|---|---|---|---|---|
| I | No | No | No | No |
| II WATER RESISTANT | Yes | No | No | No |
| III 50M WATER RESISTANT | Yes | Yes | No | No |
| IV 100M WATER RESISTANT | Yes | Yes | Yes | No |
| V 200M WATER RESISTANT / 300M WATER RESISTANT | Yes | Yes | Yes | Yes |
Notes for respective levels:
- Level I: The watch is not water-resistant. Avoid contact with any moisture.
- Level III: If the watch is exposed to saltwater, rinse it thoroughly with fresh water and dry it.
- Level IV: If the watch is exposed to saltwater, rinse it thoroughly with fresh water and dry it.
- Level V: The watch can be used for scuba diving (except for depths requiring helium-oxygen mixtures).
ATTENTION!!! For all watch categories, it is forbidden to:
- Press buttons underwater
- Adjust the crown underwater
- Unscrew the crown underwater
IMPORTANT!!!
Some water-resistant watches have leather straps. Do not wear these watches while swimming or engaging in any other activity where the strap may become submerged in water.
Care for Your Watch
- Replace the rubber gasket protecting the watch from water and dust every 2-3 years.
- If water enters the watch, have it checked immediately by an authorized CASIO dealer or distributor.
- Do not expose the watch to extremely high or low temperatures.
- While the watch is designed for normal use, avoid rough handling and dropping it.
- Do not wear the strap too tightly. A finger should fit between your wrist and the strap.
- Clean the watch and strap using a dry soft cloth, or a soft cloth dampened with a solution of mild neutral detergent and water. Never use volatile substances (e.g., gasoline, solvents, spray cleaners, etc.).
- When not using your watch, store it in a dry place.
- Avoid exposure to gasoline, cleaning solvents, spray aerosols, adhesives, paint, etc. Chemical reactions from these materials can damage gaskets, the case, and the watch's finish.
- Some watch straps feature silk-screened graphics. Be careful when cleaning these straps to avoid damaging the designs.
For Watches with Resin Straps...
- You may notice a white powdery substance on the strap. This substance is harmless to your skin or clothing and can be easily removed by wiping with a soft cloth.
- Exposure of the resin strap to sweat or moisture, or storing it in humid conditions, can lead to damage, breakage, or cracking. To ensure a long service life for the resin strap, wipe it clean of dirt and water with a soft cloth as often as possible.
For Watches with Fluorescent Cases and Straps...
- Prolonged exposure to direct sunlight may cause the fluorescent coating to gradually fade.
- Prolonged contact with moisture can cause the fluorescent coating to gradually fade. If any moisture gets on the watch surface, wipe it off as soon as possible.
- Prolonged contact with a wet surface may cause the fluorescent coating to discolor. Ensure the fluorescent surface is dry and avoid contact with other surfaces.
- Strong friction of a surface with fluorescent paint against another surface may transfer the fluorescent paint to that surface.
CASIO COMPUTER CO., LTD. is not responsible for any damage or loss incurred by the purchaser or any third party arising from the use of this watch or its malfunction.

Measuring Split and Segment Times
- Press [Button A] to start the stopwatch in Stopwatch Mode.
- Press [Button C] to record the segment time (LAP) in the central display and the total elapsed time (SPLIT) in the lower display. Two short beeps will sound. The measured data is displayed for 8 seconds, after which the display resumes showing the current measurement: the time for the next segment in the central display and the total elapsed time in the lower display.
- You can repeat step 2 as many times as needed.
- To stop the measurement, press and hold [Button C] until two short beeps and one long beep are heard.
- To resume operation, press [Button A].
- To reset the measured value after stopping the stopwatch, press and hold [Button C] until the "CLR" indicator and a beep are heard. During measurements, the display will show the intermediate measurement number.

- Repeat step 4 for each segment.
- After measuring all segments, press and hold [Button C] until two short beeps and one long beep are heard to stop the stopwatch.
- To reset the measured value after stopping the stopwatch, press and hold [Button C] until the "CLR" indicator and a beep are heard.
- A target zone signal (3 short beeps) sounds when the measured time reaches the target zone time.
- Pressing [Button B] cycles the values displayed in the lower portion of the display: SPLIT time ➡️ Current Time ➡️ SPLIT difference (difference from target segment time).
- "- : - - - -" indicates that the target zone time is disabled. A negative difference value indicates that the measured time exceeded the target time.
- Target times are displayed in minutes, seconds, and 1/100 sec for the first 10 hours of measurement. After 10 hours, the format changes to hours and minutes.
Stopwatch Memory
In this mode, you can view or delete measurement data stored in Stopwatch Mode. All data is automatically sorted into entries, each with its own number. The stopwatch memory can store up to 51 entries. If the memory is full, older entries are automatically deleted to make space for new data.
Viewing Stored Data
- In Stopwatch Memory Mode, press [Button A] and [Button L] to scroll through the entries you want to view.
