Thanks Darren,

I think you are probably spot on.

: Hi Doug,
: at a guess i would say that the small white chrono needle that
: indicates hours on the left hand register is the only correct
: hand out of the 5 hands.
: The orange chrono needle on the right does not belong to the watch
: & i think the three largest hands , centrally mounted, have
: been painted white and the hour and minute hands have been
: re-lumed. If you look at the small lume piece at the end of the
: long chrono seconds hand you will see that it has faded along
: the lines of the dials hour markers & is probably original.

: Here is my example with the handset i would expect to see on this
: model Calculator.

: I hope that helps you , Darren
