Really nice Swiss watch, no branding unfortunately. 
So we have here a square nickel silver plated case which in reasonable condition, there is fading on the corners of the back of the case, but otherwise not bad shape at all. The dial shows very little wear at all with a little dirt in the corners but nothing of any note, the numerals are clearly visible. 
Inside the case we have a Swiss 15 Jewel Lever movement the movement being unbranded as well.
Cosmetically a really nice looking period watch from pre WW2 and runs well
