Hi all, I'm new to vintage watches and decided to pick up a Rado Green Horse as my first. I don't actually have it yet since I just won the auction and yesterday. Can you guys tell me what year this green horse is from and if it's original? It would suck if I picked up a Franken-Rado. The ref. no. is 606.3253.4 with an ETA 2878 movement.Click image for larger version.
