Setup
Setting the Time
- Pull out the crown: Gently pull the crown (the knob on the side of the watch) out to the second click position. The second hand will stop.
- Adjust the time: Rotate the crown to move the hour and minute hands. Set the time to your desired current time. Ensure you consider AM/PM for the day/date change. The day and date will change automatically when the time passes midnight.
- Push in the crown: Once the time is set, push the crown back in to the normal position. The second hand will resume movement.
Setting the Day and Date
- Pull out the crown: Gently pull the crown out to the first click position.
- Adjust the date: Rotate the crown clockwise to change the date.
- Adjust the day: Rotate the crown counter-clockwise to change the day.
- Synchronize: After setting the day and date, pull the crown out to the second click position and set the time. Push the crown back in to the normal position.
Note: Avoid setting the date between 9:00 PM and 1:00 AM, as this may interfere with the automatic date change mechanism. If you need to adjust the date during this period, first set the time outside this range, adjust the date, and then reset the correct time.
Operating the Watch
Your Casio MTP-1381L-1AVDF watch is designed for straightforward operation. Once the time, day, and date are set, it will continuously display the current time, day, and date.
Water Resistance (5 ATM)
This watch is water resistant up to 5 atmospheres (50 meters). This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water, such as during recreational swimming. However, it is not suitable for diving, snorkeling, or prolonged water activities. Do not operate the crown while the watch is wet or submerged.
Maintenance
General Care
- Cleaning: Wipe the watch case and strap with a soft, dry cloth regularly to remove dirt and moisture. For the leather strap, avoid excessive moisture and harsh chemicals.
- Temperature: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect accuracy and battery life.
- Chemicals: Keep the watch away from solvents, detergents, perfumes, and cosmetics, as these can damage the case, strap, or seals.
- Magnetic Fields: Avoid placing the watch near strong magnetic fields (e.g., speakers, refrigerators, mobile phones), as this can temporarily affect the watch's accuracy.
- Impact: Protect the watch from strong impacts or shocks.
Battery Replacement
The watch is powered by a product-specific battery. When the second hand begins to move in two-second intervals, it indicates that the battery is low and needs replacement. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
Leather Strap Care
The leather strap is susceptible to wear and tear. To prolong its life, avoid prolonged exposure to direct sunlight, excessive moisture, and sweat. If the strap becomes wet, dry it thoroughly with a soft cloth and allow it to air dry naturally, away from direct heat.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs inaccurately. | Low battery. | Replace the battery by a professional watch technician. |
| Day/Date does not change at midnight. | Time is set incorrectly (e.g., AM/PM). | Reset the time, ensuring the AM/PM is correct. Advance the time past 12 PM to confirm the day/date changes. |
| Condensation inside the watch. | Exposure to extreme temperature changes or compromised water resistance. | Immediately take the watch to a qualified service center for inspection and repair. |
| Crown is difficult to pull out or push in. | Dirt or debris. | Do not force the crown. Take the watch to a service center for cleaning or repair. |
