Omega 1035 1/68 watch from garage sale

Hello community, I’m reaching out for some help. Some time ago, I found an Omega watch at a garage sale; I bought it out of sheer curiosity at the time but forgot about it due to various circumstances. Recently, after moving house, I came across it again in one of my boxes and became interested in learning a bit more about it.

Upon reviewing it, I was able to find certain features that I found interesting:

The end links are flexible on both sides; the bracelet is marked "506" at one end and "16" at the other, the crystal has a tiny Omega logo etched at the center, and in the dark, I can see a faint greenish glow.


The watch is not in the best condition, it has suffered some damage over the years. It's missing the winding crown, and it also appears to be missing the tachymeter bezel, as I can see a stepped recess around the crystal.

I wrote to a certain famous store, and they replied, indicating that they can make me an offer after an inspection.

I am from Guatemala and have no experience with antique watches or watches in general since I usually focus on hunting for vintage toys, this find was pure chance. I would appreciate any recommendations or advice regarding the sale, as I know there are very knowledgeable people here, and I value any information you can share before I decide to proceed with an appraisal for the sale.

The watch is in the same condition as when I found it at the garage sale; I haven't taken it to a local watchmaker for inspection, nor have I tried to open it myself.

Sometimes I read these and think they have to be some kind of bait, but apparently this stuff really exists. Probably paid around $50. This is the stuff dreams are made of

I'll try to take some clearer photos with another phone.

This is a new area for me; as I mentioned in the post, I usually hunt for vintage toys. My goal at that garage sale was to find action figures from the 80s or 90s, but after searching for a while, I just started browsing around and ended up finding it. It pays to check every spot, even if it takes longer; I didn't even pay much attention to it at the time, I just put it away, and it sat in a box for a while.

I typed "Omega 1035 1/68: which model does it belong to?" into Google's AI search, and while it gave me some results, it also offered the option to ask follow-up questions; I gradually pieced the message together that way. It might not be the standard way to do research, but it really helped me understand that I didn't have just an ordinary item. At first, I thought I could sell it locally for a bit more than I paid, so someone could use it for parts.

I am attaching screenshots of the inquiries; they are in Spanish because I neither speak nor write English—I am using a translator.
