1. Introduction and Overview
The FEICHONGHO W300B Automatic Watch Winder is designed to keep your automatic watches wound and ready to wear. This device supports both single and dual watch modes and features a timer shutdown function for customizable operation. Its unique design offers enhanced durability compared to traditional box-style winders, which are prone to motor carbon brush wear.
This watch winder is compatible with approximately 95% of automatic watches on the market, especially suitable for Seiko watches. Ensure the rotating center of your watch's oscillating weights aligns with the winder's mechanism for optimal performance.
2. Setup
Follow these steps to set up your FEICHONGHO W300B Automatic Watch Winder:
- Unboxing: Carefully remove all components from the packaging. Verify that you have the main winder unit, watch holders, and power cable.
- Power Connection: Connect the provided power cable to the DC-IN port on the winder unit and plug it into a suitable power outlet.
- Watch Holder Installation: The watch holders are designed to securely cradle your watches. Ensure they are properly seated in the winder's mechanism. If using for a single watch, a counterweight may be provided to balance the mechanism.

4. Compatibility
The FEICHONGHO W300B Watch Winder is designed for broad compatibility with automatic watches. It is suitable for 95% of watches on the market, with particular effectiveness for Seiko watches.
Important Note: For proper winding, ensure that the rotating center of your watch's oscillating weights overlaps with the center of the winder's mechanism. Refer to the image below for visual guidance on compatible and incompatible watch movements.

The device utilizes an electromagnetic drive principle, similar to a motor, but the watch holder is positioned far enough from the magnet (over 65mm) to prevent magnetization of your watch.

The magnetism of this device is weak, even weaker than that of typical box-style winders, further ensuring the safety of your timepieces.

The inner circumference of the watch should not exceed 21.5 cm (8.46 inches) to fit properly on the watch holder.

5. Maintenance
To ensure the longevity and optimal performance of your FEICHONGHO W300B Watch Winder, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to gently wipe the exterior of the winder. Avoid abrasive cleaners or solvents that could damage the plastic material.
- Dust Protection: Keep the winder in a clean, dust-free environment. Dust can accumulate in the moving parts and affect performance.
- Handle with Care: While designed for durability, avoid dropping the unit or subjecting it to strong impacts.
- Power Disconnection: When not in use for extended periods, disconnect the power cable from the outlet.
6. Troubleshooting
If you encounter any issues with your FEICHONGHO W300B Watch Winder, consider the following:
- Device Not Turning On:
- Ensure the power cable is securely connected to both the winder and a working power outlet.
- Verify that the power outlet is functional by plugging in another device.
- Press and hold the power button for 3 seconds to ensure it is properly activated.
- Watch Not Winding:
- Check if the watch is an automatic movement. This winder is not designed for quartz or manual-wind watches.
- Ensure the watch is correctly placed on the holder and is not loose or obstructed.
- Confirm that the winder is powered on and rotating.
- Verify that your watch's oscillating weight center aligns with the winder's mechanism (refer to Compatibility section).
- Unusual Noise:
- Ensure the winder is placed on a flat, stable surface.
- Check if any part of the watch or holder is rubbing against the winder's casing.
- The winder is designed to be quiet; excessive noise may indicate an issue.
If these steps do not resolve the issue, please contact customer support for further assistance.
