I have Belocia six watch winder which I bought 5 years ago from Amazon.com, one of the motors stopped rotating, I was able to take it out, and found out the belt in the gearbox was broken. I tried to find a belt to replace it but no luck. I bought this motor and it was much better compared to the original motors, no noise at all and it has no belt in it all geared up. Even though the other motors were working fine I decided to change all of them and my winder is working better and no noise.
