2. Initial Setup
Setting the Time and Date:
- Pull out the Crown: Gently pull the crown (the knob on the side of the watch) out to the first click for date adjustment, or to the second click for time adjustment.
- Adjust the Date: If at the first click, turn the crown to set the correct date.
- Adjust the Time: If at the second click, turn the crown to move the hour and minute hands to the correct time. Ensure the 24-hour sub-dial also reflects the correct AM/PM.
- Push in the Crown: Once set, push the crown back in to its normal position to start timekeeping.
Chronograph Sub-dial Alignment:
In some cases, the chronograph sub-dials may not be perfectly aligned to zero. This can be adjusted manually:
- Enter Time Setting Mode: Pull the crown out to the second click (time setting position).
- Adjust Sub-dials: Use the pushers (buttons) on the side of the watch to move the hands of the chronograph sub-dials to their zero positions. Refer to the watch's specific module number manual for exact button functions if needed.
- Return Crown: Push the crown back in to save the alignment.
3. Operating Instructions

- Start/Stop: Press the 'START/STOP' pusher (typically the top right button) to begin and end the stopwatch measurement.
- Reset: While the stopwatch is stopped, press the 'SPL/RESET' pusher (typically the bottom right button) to reset the chronograph hands to their zero positions.

Water Resistance (100M):
This watch is designed to withstand water pressure up to 100 meters (330 feet). This makes it suitable for:
- Daily use and hand washing
- Showering
- Swimming in pools or shallow water
- Snorkeling
Important: Do NOT operate the crown or pushers while the watch is wet or submerged in water. This can compromise the water resistance.
4. Care and Maintenance
Cleaning:
- Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture.
- For stubborn dirt, use a soft cloth dampened with mild soap and water. Rinse thoroughly with clean water and dry completely.
- Avoid using chemical cleaners, solvents, or abrasive materials, as these can damage the resin case and band.
Battery Replacement:
The watch is powered by an SR920SW battery with an approximate 3-year life. When the battery runs low, the watch may exhibit irregular movement or stop. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
