I agree with most reviews that the winder is quiet and it arrived very well packaged and that's about it. I guess most would assume the motor is magnetically shielded I have yet to test this and may never need to. Until that is I can make my watch fit the watch holder! I've read all other reviews and can not completely agree with any quality issues mentioned, this one works fine right out of the box. Is this one the exception? Hard to say at this time only further reviews of this product will tell. After contacting customer service requesting information about different watch holders for man size watch I was happy about the quick response yet at the same time disappointed about the reply to my question. I have a Bulova Accutron #63A112 and with cardboard shims on both ends I can force the watch to stay on the holder and if I leave the door open I can use it. Customer support offered plastic spacers which might be less unsightly than my now temporary cardboard but did not say anything about cost, part number or any other clue where to order them from. In my experience the only way a large watch will fit as described in other reviews is if these watches have adjustable bands and not medal bracelet style. The really sad part of all is I have yet to get my watch sized and that usually requires 2 or 3 extra links not unlike my other watches, anyone have any suggestions for winders that may work?
