Owners talk.

“

The Isotope Old Radium Bronze Pilot is praised for its vintage pilot aesthetic, balanced 40mm case proportions, and unique "Lacrima" dial design. Owners highlight exceptional customer service and a generous founder. Some find the bronze case heavier than stainless steel, and one owner describes the bezel action as poor. The watch features a Landeron automatic movement with a 40-hour power reserve and 100m water resistance. Overall, owners rate the Isotope Old Radium highly for its vintage charm and value.
