Информация о батарее
Your Casio MWA-300H watch is powered by 1 LR44 battery, which is included. The battery life is approximately 3 years. When the battery runs low, the watch may exhibit irregular movement or stop.

Operating: Watch Functions
Использование хронографа (секундомера)
The chronograph function allows for precise timing of events. Your watch features a 1/10-second stopwatch that captures elapsed, split, and 1st/2nd place times across three dedicated sub-dials.
- Starting the Stopwatch: Press button A (typically the upper right button) to start the stopwatch.
- Stopping the Stopwatch: Press button A again to stop the stopwatch.
- Resetting the Stopwatch: After stopping, press button B (typically the lower right button) to reset the stopwatch hands to zero.
- Измерение промежуточного времени: While the stopwatch is running, press button B to measure split times. The stopwatch hands will momentarily stop to indicate the split time, then resume timing. Press button B again to release the split time and display the current elapsed time.
Note: Refer to the specific button layout on your watch for exact button assignments.
Водонепроницаемость (100 метров)
Your Casio MWA-300H watch is water resistant up to 100 meters (330 feet). This rating means the watch is suitable for swimming, showering, and recreational water activities. It is not suitable for diving or snorkeling where significant water pressure changes occur.
- Не используйте заводную головку или кнопки, если часы мокрые или погружены в воду.
- После контакта с соленой водой промойте часы пресной водой и вытрите насухо.
Светящиеся стрелки и маркеры
The watch features luminous hands and markers that absorb light and glow in the dark, providing readability in low-light conditions. The intensity and duration of the glow depend on the amount and type of light exposure.
