hi guys, I’m fairly new to vintage omega watches, need your expertise to identify this omega please.sorry for the low resolution images, the second hand is blue color.

Many thanks,

 

Please provide photos of the movement and inside the case back.

 

if the pictures are from an ad ask the seller to open the watch..if he wants... Or maybe here are some experts who can tell the model from only what you post..let's see...

 

I'm sure there are many but that's not the point; this is about courtesy. A little effort from the OP gets a lot of respect.

Hi sorry guys , I was just recently given this watch, didn’t know how to open it, its a manual wind also, it’s just new to me that there is no model name on the dial

 

Omega didn't have model names for many of their watches until the last half of the 20th century. And even when they were named by Omega in sales and advertising material (e.g. Argos, T17, Foibos, Euroos from the 1930s) the dials only had "Ω" and "OMEGA".

 

Regarding opening the case. If you don't know how to do it, take it to a competent watchmaker. The case is soft gold and can be easily damaged by the ignorant, the ham fisted or the incompetent.

When it's opened, pictures (high quality ones) of the movement and the inside of the caseback will reveal all.
