Ω Omega Vintage Experts Needed!!

[drockadam]

Hello Omega Experts,

While I was at work yesterday, I stumbled across this vintage Omega womens cocktail watch. It is rather old, small and in okay condition. As soon as I saw it, I wound it and it began to run right away. The sound of the movement is perfect. It is keeping perfect time, over 24 hours.

I was looking to find information on the watch, I've done a couple Google Searches and nothing has come up about this classic cocktail watch. I am looking to sell it, just have to do some homework on the watch. The only text on the watch is on the opposite crown case side and it says "20 and then a triangle with the Omega (Ω)" inside it. The bracelet "clasp" says "Made In Germany" on it.

The dial reads:

Ω
Omega
Geneve
T Swiss Made T

I really appreciate your help.
