I have a very similar parts watch , not the same model but maybe it's closer than what you have . It's probably got the same module as yours . You are welcome to have it if you want it . The back is in decent condition with a couple of noticeable scratches but still looks ok . On the back it says :
Stainless Steel Back
40/6175
6200
Hong Kong
E Gluck Corp
and has a small alignment dot that matches one on the case .
As far as the rest of the watch , my notes said that the module worked but the buttons were non-functional , crystal is scratched , no band , LCD panel is bleeding in the corner , it hasn't been cleaned for decades
. Probably not much useable other than the back and maybe module parts .
No charge of course , let me know .
