Key Features:
- Automatic Self-Wind Movement: No battery required; powered by wrist movement. Can also be manually wound.
- 2.5D Domed Mirror: Double-coated for 99.6% transparency, enhancing dial clarity and scratch resistance.
- Functions: Month display (upper sub-dial), 24-hour display (lower sub-dial), date and week calendar window at 3 o’clock.
- Water Resistance: Water resistant to 3 ATM (30 meters), suitable for splashes and rain, but not for bathing, swimming, or diving.
2. Setup and Initial Winding
Your FEICE FM121 watch is an automatic mechanical timepiece. It does not require a battery but relies on the motion of your wrist to wind the mainspring. For initial use or after the watch has stopped, manual winding is recommended.
Manual Winding:
- Ensure the crown is in its normal operating position (pushed in).
- Rotate the crown clockwise approximately 30-40 times. This will provide sufficient power reserve to start the watch.
- Once wound, the watch will begin to operate. Continuous wear will maintain the power reserve. A full wind can power the watch for up to 35 hours.

3. Operating Instructions
The FM121 watch features multiple functions controlled by the crown and pushers.
Setting the Time:
- Pull the crown out to the furthest position (Position 2).
- Rotate the crown to adjust the hour and minute hands to the correct time.
- Push the crown back into Position 0 to start the watch.
Setting the Date and Day of the Week:
- Pull the crown out to the first position (Position 1).
- Rotate the crown clockwise to adjust the date.
- Rotate the crown counter-clockwise to adjust the day of the week.
- Push the crown back into Position 0.
- Note: Avoid setting the date or day between 9 PM and 3 AM, as this can damage the movement. If adjustment is needed during this period, first set the time outside this range, adjust the date/day, then reset the time.
Using the Sub-Dials:
- Upper Sub-dial: Displays the month. This typically advances automatically with the date mechanism.
- Lower Sub-dial: Displays 24-hour time, automatically following the main hour hand.
4. Maintenance and Care
Proper care will ensure the longevity and performance of your FEICE FM121 watch.
Water Resistance:
The watch is water resistant to 3 ATM (30 meters). This means it can withstand splashes of water and rain. It is not suitable for showering, bathing, swimming, diving, or any activities involving prolonged water immersion or high-pressure water exposure.

General Care:
- Clean the watch case and strap regularly with a soft, dry cloth.
- Avoid exposing the watch to extreme temperatures, strong magnetic fields, or harsh chemicals.
- If the watch comes into contact with saltwater, rinse it gently with fresh water and dry thoroughly.
- Store the watch in a cool, dry place when not in use.
5. Troubleshooting
If you encounter issues with your FEICE FM121 watch, refer to the following common solutions:
Watch Not Running or Stopping Frequently:
- Insufficient Power Reserve: As an automatic watch, it requires motion to wind. If not worn for an extended period, it may stop. Manually wind the watch by rotating the crown clockwise 30-40 times.
- Lack of Movement: If your daily activity is insufficient to keep the watch wound, consider manually winding it daily or using a watch winder.
Date/Day Not Changing Correctly:
- Ensure the time is set correctly, especially the AM/PM cycle, as the date change mechanism is linked to the 24-hour cycle.
- Avoid manual date/day adjustments between 9 PM and 3 AM. If you did, the mechanism might be temporarily misaligned. Allow it to cycle naturally for a day or two.
Condensation Inside the Watch:
- Small amounts of condensation that disappear quickly are usually normal due to temperature changes.
- If condensation persists or appears as large droplets, this indicates a breach in water resistance. Seek professional service immediately to prevent damage to the movement.
