Vintage 14K Gold Omega Identification

Found this watch when going through my grandfather's belongings after he passed. My grandmother thinks it must be close to 50 years old. There are no identifiable serial numbers on the outside. Hard to see in the picture but it does say 14K GOLD on the case. The band is a Fixoflex and I don't know if it's the original.

Anyone have any ideas? Thinking of taking it for a restoration appraisal.

Very nice and IMO original! probably a .354 "bumper" caliber and ??? 2816 SC version/model ??? The real specialists here will tell you more....congrats!

My guess would be Ref. 6525 solid 14k case with Cal. 351 bumper automatic
circa ~1952? and it look fine to me.

I think you might be right!
