The pilot watch with magnetic field protection

Our experience in manufacturing precision cockpit navigation clocks is still reflected today in Sinn's 656 series. This includes the extra large numbers, for example, as well as the contrast to the glare-free black dial and the special paint on the indices and hour and minute hands, which remains luminous for a very long time. All of this ensures easy readability in any situation.
