I picked up this non-running Hamilton with a Swiss ESA 9158 electronic movement on the bay for $25 . It has a screw down crown , and when it arrived I could see that a bezel was missing . I searched the internet to see if I could find a picture of what the old bezel looked like , with no luck .
The rubber watchband was salty , dirty , and twisted into the shape it was stored in .
When I opened it up I was presented with a movement that was swimming in oil ,...you could almost pour the oil out . I had to clean my tools and work surface when I got it out . I removed the dial , hands , and dial ring and cleaned them up hoping that the finish on the dial and hands wasn't ruined .
I was able to find a complete working movement for $20 .
Fortunately, after cleaning up the case , dial , hands , and watchband , everything looked good enough to re-use with no apparent damage done by the oil soaked parts .
I reassembled the watch with the donor movement and it was off and running .
I checked my stash of parts to see if I happened to have an old bezel that would fit the case . I pulled out a Seiko bezel that I had changed out on a Seiko 6138-0011 UFO / Yachtsman I have and it fit . I used a piece of brass wire of the right diameter to form a bezel spring to fit between the bezel and case , as each part had a slot where a ring would fit . Luckily all the parts fit very well . The bezel fits firmly and turns as it should .
The Seiko UFO ....
And The Hamilton Electronic...I have since , reset the day and date...
