I'm new here, and looking for information about this watch. I bought it in a second hand dealer about 20 years ago and it would be fascinating to learn it's history. I replaced the bracelet when I got the watch with a non-Omega one. Any help appreciated!
You’ll need to post better photos and, if possible, a photo(s) of the movement showing the serial/movement numbers for the information you seek. But given that it appears to be a gold (soft metal) watch, your metal bracelet will be doing irreparable harm to the lugs. Also, you’ll be amazed at how much better it’ll look with a replacement crystal.
