Vintage Omega Bumper(?) Watch 海外 即決

Or rather， I believe it is. Can’t tell if it’s made with gold or not， or if it’s just gold-toned. It works， but only when I twist the knob first， compared to only shaking it first. The bumper(?) mechanism inside feels like a teeeny tiny rubber ball bouncing up and down. There is also an almost-difficult-to-see-unless-looking-for-it section along the far right of the face that looks like either part of it may be missing， or something happened to it there. Uncovered while cleaning through a heavily cluttered room; it was stored within a series of ziplock bags. It has been washed with dish soap and water. The band holes seem rather tight; I don’t know how often this has been worn， or if at all. And since it was uncovered by sheer miracle， it likely hasn’t been touched in at least over a decade. The story is the same for the box and its case. They were found together in another part of the room， also in ziplock bags. The case is made of plastic， and there are two random wristband links inside， from a different watch. No idea if they’re Omega pieces， or not. The box is a bit beat up， and its insides very easily attract dust and dirt—even though I wiped them off and out with a damp paper towel， months ago， and kept them in a ziploc bag. It weighs about 1.5 oz—which is 42-43 grams， or so? I’m storing the watch inside of the box， since there is slightly more room for it to “stretch its legs”， as opposed to being cramped into the plastic case， as shown in a photo. Being sold as-is. I know it doesn’t matter what method this watch is to be used for， once it leaves my hands， but I would hope and wish that it goes to a person who will cherish it and wear it for life and not to someone who will just resell it for profit. Knowing it’s being put to great use， being worn and appreciated， would calm my heart.
