3. Setup Instructions
3.1 Initial Winding
As an automatic mechanical watch, the BY5121 does not require a battery. It is powered by the natural motion of your wrist. However, for the first use or after a period of inactivity, manual winding is recommended to initiate the movement and ensure accurate timekeeping.
- Locate the crown on the right side of the watch case.
- Ensure the crown is in its normal, pushed-in position (Position 0).
- Turn the crown clockwise approximately 20-30 times. You may feel a slight resistance; do not overwind.
- The watch should now start ticking.
3.2 Setting the Time
- Pull the crown out to Position 1 (the outermost position).
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Once the time is set, push the crown back into Position 0 to engage the movement and start the watch.

4. Operating Instructions
4.1 Wearing the Watch
For optimal performance, wear your BENYAR BY5121 watch regularly. The automatic movement relies on the motion of your wrist to keep it wound. If worn daily for at least 8-10 hours, it should maintain sufficient power reserve.

4.2 Power Reserve
If the watch is not worn for an extended period, it will stop. Simply re-wind it manually as described in Section 3.1 and set the time before wearing it again.
5. Maintenance
5.1 Water Resistance (30M / 3ATM)
The watch is designed to withstand 30 meters (3ATM) of water pressure. This means it is suitable for daily use, such as hand washing, rain, or accidental splashes. It is not recommended for showering, swimming, diving, or any prolonged water immersion. Always ensure the crown is fully pushed in before any contact with water.

5.2 Cleaning
- Wipe the watch case and crystal with a soft, dry cloth to remove dust and fingerprints.
- For the leather strap, avoid excessive moisture. If it gets wet, allow it to air dry naturally. Do not use harsh chemicals or abrasive materials.
5.3 Storage
When not wearing the watch, store it in a cool, dry place away from direct sunlight and strong magnetic fields, which can affect its accuracy.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs inaccurately. | Insufficient power reserve (not worn enough or not manually wound). | Manually wind the watch by turning the crown clockwise 20-30 times. Wear it regularly. |
| Condensation under the crystal. | Sudden temperature changes or water ingress. | If minor, it may dissipate. If persistent or severe, seek professional service immediately to prevent damage. |
