The Citizen B642 is a solar-powered quartz chronograph movement manufactured in Japan. It features a vertical bi-compax layout with a 60-minute totalizer at 12 o'clock and a small seconds subdial at 6 o'clock. The movement draws power from any light source through Citizen's Eco-Drive technology, eliminating the need for battery replacements. This caliber appears in Citizen sport watches such as the CA7045 and CA7020.
