Datejust 1601 hand question

[jackruff]

I've been looking at a vintage datejusts and noticed most have stick hands. I came across this 1965 with these hands - Dauphine I presume.. I have seen models from 64 and 66 (and other years) all with stick hands. So is this just a normal variance or non- original? Or just one of those Rolex things for no rhyme or reason just an anomaly/difference. I also notice that some models (Like this one) have lume spots on the outer of the indices - is this something that was added as standard at some stage because some models don't seem to have them or perhaps missing over time? (seems to be the older ones without.)

All help greatly appreciated.

Regards
