Setup
Initial Power On
Your watch comes with a pre-installed battery (CR2032). If the display is blank, press any button to activate it. If it remains blank, the battery may need replacement.
Setting Digital Time and Date
To set the digital time and date:
- Press the MODE button repeatedly until the time setting mode is displayed (usually indicated by flashing digits).
- Use the START/STOP button to select the digit or setting you wish to adjust (e.g., hours, minutes, year, month, day).
- Use the SPLIT/RESET/SET button to increase the value of the selected digit. Hold the button to rapidly advance.
- Repeat steps 2 and 3 for all desired time and date settings.
- Once all settings are correct, press the MODE button to exit the setting mode and return to the normal time display.
Setting Analog Time
The analog dials are typically synchronized with the digital time or set independently through digital controls. If your analog hands do not match the digital time after setting, consult the specific instructions for analog hand adjustment within the digital setting mode, which may involve a combination of button presses while in time setting mode.
Band Adjustment
The stainless steel band is adjustable to ensure a comfortable fit. To adjust the band:
- Locate the clasp mechanism on the band.
- Use a small tool (like a flat-head screwdriver or a watch tool) to lift the locking plate on the clasp.
- Slide the clasp along the band to the desired position.
- Press the locking plate back down firmly to secure the clasp in place. Ensure it clicks securely to prevent accidental opening.

- To reset the stopwatch to zero, press the SPLIT/RESET/SET button when the stopwatch is stopped.
Backlight
Press the LIGHT button (bottom left) to illuminate the digital display for a few seconds, allowing you to read the time in dark conditions.
Temperature Display
To view the temperature, cycle through the modes using the MODE button until the temperature is displayed. Note that the temperature sensor is located on the watch body, and readings may be influenced by your body heat. For a more accurate ambient temperature reading, remove the watch from your wrist for approximately 15-20 minutes.
Maintenance
Water Resistance
Your MASTOP Model 1220 watch is water resistant to 3ATM (50 meters). This means it can withstand daily splashes, rain, and brief immersion in water. However, it is not suitable for swimming, showering, diving, or snorkeling. Avoid pressing buttons while the watch is wet or submerged to prevent water ingress.
Cleaning
To keep your watch clean, wipe the case and band regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish.
Battery Replacement
The watch uses a CR2032 coin cell battery. When the display becomes dim or stops functioning, it's time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
Troubleshooting
Difficulty Setting Time
If you encounter difficulty setting the time or other functions, please review the 'Setup' section carefully. Watch settings often require precise button presses and sequences. Patience is key. If issues persist, ensure the battery is not low.
Inaccurate Temperature Reading
The watch's temperature sensor is affected by body heat. For an accurate ambient temperature reading, remove the watch from your wrist and allow it to sit in the open air for 15-20 minutes before checking the display.
Watch Band Pinches Hair
Some metal link bands may occasionally catch arm hair. Ensure the band is adjusted to a comfortable, but not overly tight, fit. If discomfort persists, consider consulting a jeweler for alternative band options or adjustments.
Small Text on Watch Face
The watch face features detailed information in a compact design. If you find the text difficult to read, especially in certain lighting conditions, using a magnifying glass may assist in viewing the smaller indicators.
