Looking for advice on vintage seamaster

I've got this Seamaster I picked up and looking to get some info on the case and some of the missing parts. Long time lurker here so figured I'd post up!

Movement is a 562, 18M serial. The case is marked 14770 - 4 - SC, but I have not found an exact match to this elsewhere. Lugs are gold rolled, so I'm assuming the bezel should have been as well (but it's missing). Crown is a replacement, missing hour/minute hands. The dial has a neat linen finish, but I'm unsure if it's been redialed. It's an odd one with the long R and the rounded S, on the logo which I have not really seen. From my guess, this would be a '62 and likely a Canadian market only model.

Any feedback or help I could get would be much appreciated! A source for a bezel (used) would also be great, but I'm unsure of where to start looking for one or how specific it would be to this specific case. Thanks in advance!

Welcome to the forum!
I'm not an expert, but a bezel is very hard to find. You could get a complete case, but I doubt any of these solutions would be worth your time.
Dial condition is bad. The lugs appear to be dangerously overpolished. This watch needs a lot of work, time and money and in my opinion that makes it unworthwhile fixing.
If you got it for a good price I'd suggest you sell it for the parts, mainly the movement, if it's any good.
Even if you were to fix it up you would be left with a less than stellar watch.
I hope this helps.
Edit: forgot to say that you should add a movement pic as well.

I was going to comment but @ZIELSZIEK has said all that needs saying.

Thanks for the feedback guys,

I'll get some better photos,but I can see why with the ones I posted the dial looks much worse than it is same with the lugs. In person the lugs look excellent with straight lines and no spots worn through the gold filled portion. Likewise the dial has some character, but it's a really weird deep vertical linen cut so it's very directionally sensitive, that picture is probably the worst direction. I also have the means to manufacture a bezel pretty easily in brass (to be plated) or SS, but I know plating will be incredibly hard to match.
