Real or Fake? PLEASE HELP?! :)

[STaylor]

Hi everyone,
I was given a fair condition Rolex as a payment for some freelance work. So I'm certainly hoping it is worth something, but I am not sure of it's authenticity because i do not have the box or any documents. Can anyone give me any advice?

The face reads:
"Rolex
Oyster Perpetual
Datejust
Superlative Chronometer
Officially Certified
Swiss Made"

The inner rim is etched with "Rolex" and "F714983"

Any help or advice on what to do with this piece, is greatly appreciated! Thanks!
