Sometimes you see photos where the second hand lume is a different colour (usually orange) and the minute/hour hand are cream. Sometimes all the hands are the same colour lume, like in this example. I don't know if the different lume colours are original or whether they have been done when the watch is seviced/overhauled. I've an A3643 and I'm pretty sure that it is a one-previous owner watch and hasn't had much in the way of servicing (a service mark from 1978 was probably the last time the case was opened) - all hands have the same colour lume as in the OPs example. I actually like the different lume colour for the seconds hand though... I tried to get my watchmaker to relume the hands, but he refused!
