This large, round watch has a thin, flattened bezel with an exterior tachymeter reading in gray. The patterned dark gray dial face is accented by black subdials, and it offers white luminous Dauphine hands (with seconds hand) and a date function at 4 o'clock. The bracelet band is joined by a push-button clasp. Other features include a screw-back case, screw-down crown, scratch resistant mineral crystal with anti-reflective coating, and water resistance to 660 feet (200 meters).

This watch is powered by Citizen's unique Eco-Drive, which absorbs sunlight and any artificial light through the crystal and dial to recharge the watch continuously. With regular exposure to light, the Eco-Drive continuously recharges itself for a lifetime of use. This watch's Eco-Drive provides a 240-day power reserve, and it can be recharged with just 3.5 hours of exposure to light.
