Help required - a couple of vintage Omega watches

Hope someone here can help. My father recently passed away, my mother a few years earlier. Among the various items left were a couple of Omega watches and I am no watch expert. I'm calling them vintage as I recall them having them for many years but apologies if they are modern!

I am planning to take them to a local jewellers for valuation for probate purposes but I wouldn't mind going in with at least some knowledge of whether these have any value. I have done a quick trawl of the internet to find similar but can't find anything that close. Hope they aren't knock offs.....;-)

First is a c31mm men's watch. It has De Ville and Turler markings. It's similar to a Seamaster but doesn't have a logo on the rear. Strap seems to be new/nothing special.

Second is a 16mm ladies gold watch with 18k gold strap. No dial marking other than Omega logo.

Thanks

Thank you for your replies, much appreciated. The caseback on the men's watch is gold so hopefully it's solid gold. And Davidt, I think your dates are about right: we lived in the USA around that time (we returned to the UK in 1972) and I would have said that they were purchased there although I have no paperwork
