Welcome to the forum. It’s customary for new members, particularly those seeking help and advice, to introduce themselves in a preamble before seeking advice.
That said , the photos which I assume are the seller’s are very poor and I’d be hesitant about buying a watch relying on them to ascertain the condition of the watch.
The movement shots are equally poor and the movement looks dirty and unserviced in the dim lighting and on the basis of the very worn gasket, at the very least (depending on where you’re located) you should factor in a further £200 approx for a full service.
I stand to be corrected but I also think that the cyclops crystal is both aftermarket and horrible and should be replaced.
I haven’t commented on the dial or hands or case because of the photos.
You don’t mention the price but, on the basis of your photos, unless it’s extremely inexpensive, I’d keep looking.
