My grandfather had passed away and left me this Omega watch that has .925 Sterling Silver imprinted on the back. I was trying to get a better sense of it's age and model and have not been able to find it. I was hoping someone could help ID this for me?

 

Style says late 1970s early 80s.

 

The model number is inside the caseback.

Agree on late 70’s early 80’s.

Value is most likely not much more then scrap silver value.

 

Agree on the period stated by the others.

You might want to get a watchmaker to open the case back, and retrieve the model number and serial number to estimate year of manufacture. If you wish to get a clearer understanding, you could use the numbers to order a Omega Extract of Archive.

 

I might say it’s older, maybe early 70’s. Judging from the case size, I’d be surprised if it had something other than a cal 620 or 625 in it, they were very commonly used on smaller manual wind dress watches of this style. Hands make me want to say that too. In any case there’s no telling for sure until the back comes off.
