Personally I prefer the style of the second example - like gold and steel, two-tone dial, the bracelet is also stamped Omega and prefer the lugs style. But the dial is way too far gone for my taste. The condition is the first watch is higher.
Attractive patina is usually defined as uniform aging of the dial. This example shows some of this, which I could learn to like, but there is also a massively distracting damage around the center and the lume color isn’t attractive.
Perhaps worth rethinking your strategy here. You want to buy something you like and enjoy wearing. Not something with patina just because it’s sort of cheap.
Now, if your budget is only about 400-500$, then maybe check alternative (Geneve models, which were entry level watches for instance) but which you can get in great condition for about this budget.
Defaults and defects on vintage watches, such as poor dial condition, soft lugs etc., will only bother you more as you wear them and get to know other references. So if you’re unsure about it from the beginning, it’s usually best to pass. Save the money for a better example.
Only my two cents. Good luck with the search.
