I immediately thought this was a fake....

....but now I'm not so sure. What I can't work out is how much is correct. This has just been inherited by one of my close friends, so it carries a lot of sentimental weight. He was told his mum bought it for his dad around 1940 in South Africa. First, sorry for the crappy camera phone pics - I've not got a proper camera with me but can follow up with decent pics if necessary. First sight I got of the watch was this:


I took one look at the sub dial markings and the 'non magnetic' text and immediately assumed t was a fake.


Nothing helpful on the case back and no hallmarks or anything else on the case itself I could make out.
Imagine my surprise when I popped off the case back and found this:



I think this might be a 26.5 t2 or t3 - does this sound right? Definitely genuine. serial number is 9466774, which I think probably puts the movement around 1941-2.



Case back has multiple servicing marks and the ref 2224. I can't find anything on this but I might be being drowned out by noise on the later bond Seamaster.

So I'm currently faced with a movement that I'm sure is genuine, a dial I'm sure is repainted, a caseback that feels like a genuine omega and a case (of unknown material) that kind of doesn't - can anyone help me fill in the blanks and correct my assumptions where necessary with these limited photos?

Cheers!

Looks legit to me except for the redone dial. The exact caliber ref (T2 or T3) is written on the mainplate under the balance.
