Can someone tell me if this is real or fake?

[whomeeeeeeee]

Found this as part of a relatives estate. It's got weight and smooth second hand movement but the serial number (173316) does not say "rolex" and when I looked it up, it shows as 1965? Also the holograph on back doesn't look right but not sure what year they started using those. Any help identifying this as real or fake would be greatly appreciated.
