Wrong battery with wrong voltage and battery chemistry.

Or dirty contacts to the battery.

You need a watch back press if it is push on, or a back removal tool if it is a screw back..

The simplest solution to this is to get a watch repairer to do it for you. They usually only charge a small fee to do it and just takes a few minutes.
If you can get the back cover off the watch the battery will have a size code marked on top of it, often an AG- or an SR- number. This will give you the size of battery you need. I think your watch has a 'push fit' back plate.
*Note* If your using something metal as a lever it could scratch the watch.
CAREFULLY using a blunt edged lever GENTLY lever the back plate off. This should reveal the battery. When refitting the back plate it should click into place using a firm, even and gentle pressure.

There is no CR920 3 volt battery and especially will not work for any Lorus watch. There is the SR920SW and SR920W series 1.55 volt silver alkaline cell.. 9 mm diameter x 2.0 mm height is an impossible size for this old Lorus watch.

You are probably going to have to look for an identical watch for parts.You might try this site:
http://www.esslinger.com/watchparts.aspx?gclid=COCr3t2F9KUCFcIKKgodgiARnA which is parts for watches. I'd have a look on ebay as well for a watch that is not working. Of course it does depend on the part you are looking for. I am also wondering if the inner parts for another Lorus mickey moue watch might fit, but maybe you don;t wish to change it out from the original.

mcdevito75 here, Any small watch repair shop can replace the strap for you. Ebay may have Mickey Mouse replacement straps if you"d like a Mickey Mouse strap.

I will explain from the last question asked. To get it going you have to visit your nearest watch repair shop and ask for estimate. Shop owner told you things he/she do not understand at all - self winding watches CAN NOT BE OVERWOUND, so, there is the question: are you sure this watch is self winding? I've experience of 26 years of watchmaking and have never came across Mickey Mouse watches having self winding movements. As far as I know, all MM watches are battery driven, but in case if you really have the mechanical one - you are lucky. That means there were past times when those watches were fitted with mechanical movements and now they are rarities. Even if your watch is not self winding, but is mechanical (not battery driven), visit your nearest watch repair shop and ask to check this watch out. In case if it is mechanical - pay the money and get it fixed (you will be a winner anyway). If it is battery driven - put it on your shelf where your's mother in law picture is and treat it accordingly. Rate me , plz.

mcdevito75 here, hello miss d, the first Mickey watch Disney came out with was in 1933, Mickey was invented in 1928, if this is a picture of your Mickey above, then it wa made in the early 1980"s. If it's working very well it could be worth a collector value of approx. $30.00 --$50.00
