Help in Identifying please..

I received a Rolex Tudor as a gift in 1965 (that pretty much dates me). The watch was new and yet it came from a jewellery store that may have held old stock for some time. It says Tudor Oysterdate on the front top, above where the "6" would be it indicates Shock Resistant and below where the "6" would be it indicates Swiss. The back of the watch indicates original oyster case by Rolex Geneva. It is a wind watch (not self wind) and has a Rolex emblem stamped on the winding stem. Sorry for the poor picture quality.

Question: Is any one able to help me determine the year and model of Rolex this may be? Thanks.
