·Hello everyone! this is my first time posting. I have an omega constellation that I'm assuming is ~1960s. I can't really identify it because when I do a reverse image search all the hits I get non have a round magnifying window. The story behind this watch is a bit sad. My late cousin which is way older than me died. He had a gambling addiction so he was known to pawn jewelry (that why it has no bracelet). Even though he had a trust he didn't have full access to it and would get an monthly allowance. After he died I was helping my cousins clean the house. We found a bag with some old watches which they almost threw away. I told them what it was they didn't want them and gave them to me. Nothing really note worthy in bag besides this. Even though my cousin had other expensive watches he would pawn them or sell them off. Weird thing is this is the only one that was found. Most of the bag had casio watches which he would always wear, a zodiac and 2 smart watches. Sorry for the long story. A bit more on the watch, I'm sure it never has been serviced. I could be wrong. The mechanism works properly and keeps time . I'm assuming it's not gold plated because it's really heavy and I remember him wearing it and it had a gold bracelet. This watch is almost as heavy as my certina ds podium or my Claude Bernard aquarider. I'm afraid of taking the back plate off and damaging the watch. Thank you in advance for your help.
