Help finding this seamaster reference number

Hello everyone, I found this vintage omega seamaster listed for sale for about 200 Usd at FM (price shouldn’t be a source for concern since vintage watches here in Chile tend to be a lot cheaper). I’m tempted to buy the watch, but I’m not quite sure what’s the Ref number, so far I’m inclined to think it’s a 2828, but I’ve done a lot of research and I’m still not quite sure. Im also wondering if it’s in all original condition or if it’s had a redial, because it does look a bit, well, underwhelming in the dial print quality. The seller hasn’t been able to open the watch, so I’ve got no movement pictures until I go and see it in person. I’d like to know if you think it’s a watch worth buying or should I steer clear from this one. Thank you very much for your help!!

Agreed on 2828. Need better photos of the dial to confirm originality, though. If redialed, I wouldn’t pay $200 myself.
