Stainless case with 14K indices, bezel, and Rolex crown. Rolex signed case back. Black dial with an almost gold dust sparkle to it, "Tudor Oyster Prince Rotor Self-Winding" written on dial. I had it thoroughly cleaned and serviced late 2015, 34mm case size, 19mm lug to lug. Alligator print genuine leather strap and stainless buckle. 

Fully functional and impressively accurate for it's age. I'm fairly certain its a 7964 model but I'm no vintage Tudor expert and there's no model number listed on the case that I can find.

There is no numbers or any other information etched between the lugs.
