Need Info, On My Watch.........constellation.

Hello, first post on an interesting site.
I bought a Constellation in the early 1980's, and was wondering what the watch is worth now, as I am interested in selling it. My eyes can't see the hands!!!!!!!!
The number on the tag is "0112010" and "1445".
I sent it to the NY service center, and had the diamond bezel fitted. Watch has been regularly serviced at Omega certified facilities here in So Cal. Heres a pic........

Right now, I have no idea........if I was dealing drugs, I could get you the weight today...........You guys know more about this than I do...........
I'll try to get it weighted.......I'll check my I phone for an app. !!!!!!!!!!!!!!!
