Hands
6309 diver handset
ProbableBaton hour and minute hands with a lollipop seconds hand — the dive-line handset shared across the 6105, 6309, 7002 and SKX generations. Its interchangeability across four generations is exactly why a handset alone cannot place a watch in one of them.

PeriodProbableWhole production
Original hands stripped and re-filled with modern luminous compound. Very common on vintage divers and often the only way to make a watch legible again. It should be recorded — relumed hands cannot then be used as evidence of the watch's age — but it is restoration, not deception, unless it is concealed.

Replacement hands sold for the dive family. Lume colour, counterbalance shape and the taper of the seconds hand are the comparison points against a documented original.
