My grandfather has long since passed but I have had some time to look into his watch which he gave to my mom who then passed it on to me.

All I know is my grandmother purchased it with her first pay check as a nurse sometime after 1945-1950. Some interesting engravings on the case back too (not sure what they mean).

Any help information would be greatly appreciated.

 

The scratches on the case back are likely marks from watchmakers who have serviced the watch in the past.

 

Thanks!

 

I get excited for any thread titled "Grandfather's Omega"! You've got some great advice already, but I would like to know if you plan on wearing it? That's a lovely and honesty-aged dial also, and to think that your grandfather looked at that same dial and hands as you are today is something really special.
I'd maintain it mechanically and leave the cosmetics alone, and also consider ordering an Omega Archives extract to find out a little more about when it was made, if that interests you. Enjoy that beauty!

 

Thanks for the reply! And yes, I am absolutely going to wear it. Thanks again!

 

Very solid watch with a highly respected 200 series movement. Congratulations - these are true workhorses. You probably know this but just in case, the caseback number and serial number on the movement both date this piece to somehwere around 1963. I have 3 Omegas from that period, which was a golden age of Swiss watchmaking. I would put an 18mm strap on it, as the current one is too narrow. Also, it should be serviced before too long if you intend to wear it. Take good care of it and it will outlive you, and be enjoyed by the next generation.

 

Thank you kindly for your reply. I will look for someone who can service it tomorrow and will also get a proper 18 mm strap. Thank you once again.

 

There is few things better than wearing a grandfathers omega! Nice looking watch!

 

This watch appears in Omega's vintage site, and based on the pcture, I'd say a black pigskin strap would serve you well!
