Newbie seeking assistance.

[arox]

Hi all, I am new here so please forgive me if I am doing the typical newbie thing and posting in the wrong spot or asking stupid questions.

I have done a lot of internet searching and it always leads back here so hopefully someone maybe able to help me out.

I have a watch that was owned by my father. It is marked Tudor Oyster, has a large rose, 21 jewels, shock resisting and from what I can make out the serial number is 339657 and the model number is 7934, oh yes, it also has a red second hand.

Now I have looked at many sites, googled all the details and have not been able to find any info or pics similar to this watch, which makes me wonder whether it is in fact genuine or not.

I have attached a couple of photos, sorry the quality isn't so great, but I am hoping someone here might check them out for me and let me know whether this is a genuine article or not. Any assistance at all would be greatly appreciated.
