Need help with identification!

[tkind]

Ok, so I'm new to this forum. I have received a Rolex Oyster Perpetual Date passed down through my family. It was originally bought by my Great Uncle. From what I have been told, this watch is from the 1950's. Something unique to this watch that I have seen only a few times is that the word "Rolex" is raised, not flat. I have looked endlessly for a similar watch only to find nothing. It is no longer correctly keeping time, as it has sped up. What I'm asking, is if anyone can identify this watch(Year, movement, etc.). I understand that a lot of these questions could be answered by opening the watch up. I'd rather not spend the money though. I have attached a picture of the watch. Any help would be great. Thanks!
