Any thoughts or advice on this Datejust?

I suppose if you MUST have a 1963 watch, and you feel this watch is not over priced in your locale then you might have to settle for proper year like this watch and simply hunt down a period correct dial. Finding a correct style non-quickset datejust dial for that year watch is no biggie.

The only reason for doing this is to have a birth year watch. It would be a bit absurd to have a birth year body but later dial/hands so, yes, as you say, maybe the answer is to go for this and then search for an authentic dial, but the problem there is that there’s no guarantee I’d end up with 1963 parts, only pre ‘64 parts, plus the cost of those additional parts would make the project more expensive than if I hung on until I found a genuine ‘63.

I think, therefore, it would be best to wait. Besides, my other interest is a ‘63 Railmaster, so I’ll keep my options open and see what comes up first.

you might try a WTB posting on VRF or TRF as there's loads of members located in the states where vintage datejusts are more plentiful and reasonably priced, and turning up a nice original '63 will be more likely. I would also hold out for one with the bracelet, but bear in mind anything that old is gonna have a very loose bracelet so factor in around $400 to $500 to get it rebuilt.

I believe that you should wait for the one that you really want. From what I read you are not entirely convinced. You should be convinced 100%! Go in for the watch you want and dont look back!

All the best bro!

Be patient, dont rush into this. I rushed into my first rolex and ended up with a frankenwatch that had to be returned. Luckily it was ebay and I got my money back.
