This is my review of my cheap 4 watch winder. This winder cost about USD 75 and can wind 4 watches. It is brand-less and I purchase it from Formosa Watch Co. They are one of the largest watch chain shop in Taiwan. Actually, this watch winder is the same as the one the watch service department use to wind and test watches being serviced. As you can see from the photographs, the build quality is not that bad. It could be better. The body is made of plastic and finished to look like it is made of wood. The base is made of black plastic. The bottom is made of slip resistant rubber. There is 3 'cooling' holes at the base and 1 on the round body.
The winder itself is not big. It stands 8 inches tall and 7 inches wide. The base is 4 inches in diameter.
The winder is mains powered and it is not universal. It uses 120V 50/60 HZ. It provides 5/6 RPM 3.8W dual rotation motor. To change the direction of rotation, the winder has to be switch off (via a red toggle switch) and wait 10 seconds. Switch the winder on and it rotates the opposite direction. There is no provision for the winder to use batteries.
The watches are held in place by spring tension of the watch mount. The mount itself is rubber lined (central section only) to prevent scratches to the watch case back. This is very useful if you have watches with display back as it will not scratch the crystal. I have mounted watches up to 46 mm on the winder and it rotates with no problem. I would not mount metal bracelet watches on this winder as the watch mount can scratch the inside of your bracelets.
It is very utilitarian in its look. It does look like something that would not be out of place in a Transformer movie. The watch mounts does provide a limited amount of adjustments. It can be adjusted slightly along the vertical and horizontal plane via the screws positioned all over the winder.
Overall, for about USD 75, I cannot fault the winder. It can wind 4 watches and can take 4 watches up to 46 mm in size. It may not have the looks of more expensive winder but it does what it is suppose to do. It would be great if it had a universal powered motor and if the entire watch mount was rubber lined. But as it stands, it is great value for money.
