Every well-preserved looking 'Croton Aquamedico' I can find has fully lumed hands and figures (not dots), a red second hand, and dial markers at 1-second intervals. There seems to be very little of the original dial left.
Lots of examples and threads on this brand and model are out there, to compare yours against. (thanks) (thanksPurchases made through these links may earn this site a commission from the eBay Partner Network)
