クロノグラフ（ストップウォッチ）の使い方
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.

- Resetting the Stopwatch: After stopping, press button B (typically the lower right button) to reset the stopwatch hands to zero.
- スプリットタイム測定: 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.
Water Resistance (100 Meters)
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.
