Been offered 2 watches but I’m unsure if they are worth it

Hi everybody. I’m very new to vintage omegas and said to a Jewellery dealer near me that I wouldn’t mind getting into them.

They had 2 watches in store from an elderly couple as a trade in, and I’m tempted by both, but I’m not sure what I should be looking for.

I’m going there today to remove the back of the cases to have a look at the movement and check to see if they are gold (been told they are), but I don’t really know what I should be offering in terms of price as I haven’t seen that many similar models, especially like the seamaster which I’m wondering if that should be a red flag or maybe it’s a good a thing.

I fully understand the photos are not the best but that’s all I can offer now to see if today’s trip is worth it or not.

Do they look like they are worth buying? And what kind of price should I be realistically looking at?

Thank you all in advance

They are asking £550 for the geneve and £700 for the seamaster which seems high looking at the condition.

I can’t find too much information on the case weights to work out if this is a fair price if they are solid gold though.

I do like them with the dial patina, and I’m hoping if I can get the scratches worked out on the glass they will look quite nice
