Hello. I'm looking for help identifying this gold Omega watch. It was my grandfathers and I believe it's from the 60's but I'm not sure. Thanks.

Thanks. I couldn't find anything on the Internet or on the Omega vintage watch database. Does anyone have any insight as to its rarity or value?

 

I believe it is uncommon. However the value is not too high, due to low demand to this watch type.
Probably the value would be the weight of the gold + 10-20%.
Since it is a heirloom, the value to you should be priceless..........

 

Yes, unfortunately not a desirable style, so not much value above gold content as noted by Private.

 

Thanks the info help. If anyone finds any further info, please let me know.
