Citizen Eco-Drive METAL AW1365-19P featuring a light-absorbing "solar ring" instead of solar cell panels, allowing opaque metal dials to be used. The watch dial is inspired on German World War II "Beobachtungsuhr" watches that were issued to German military personnel. Strictly translated "Beobachtungsuhr" means Observer's watch or Observation watch but these watches are often referred to as Navigator's watch, Pilot's watch, B-watch or even "Flieger".
