The Citizen CA4640-50E is a men's chronograph watch with a polished stainless steel case and a silver-tone stainless steel bracelet. The bracelet closes with a stainless steel fold-over push-button clasp. The case measures 41mm across and 12mm thick.
The dial is black with index hour markers and silver-tone luminous pencil-shaped hands with white accents. A tachymeter scale sits on the flange. The bezel is fixed, and the textured push/pull crown works with the function pushers.
It has a chronograph, 12/24-hour time and a date display. The B620 Eco-Drive movement is recharged by any light source, so it needs no battery changes. A full charge gives a 9-month power reserve. A mineral crystal protects the dial from scratches, and water resistance is rated at 100 meters.
