The Citizen Eco-Drive Sport Casual Men's Quartz Watch (Model CA4505-04E) is a 44mm chronograph timepiece powered by Citizen's proprietary Eco-Drive solar technology, which converts any light source into energy — eliminating the need for battery replacements. The case and fixed bezel are crafted from black ion-plated stainless steel, measuring 13mm in thickness, and the dial is protected by a mineral crystal.

The black dial features large luminous Arabic numerals, luminous sword hands, and three chronograph sub-dials for elapsed time tracking. A pulsometer scale rings the outer dial, and a date window sits at the 4 o'clock position. The watch operates on a Japanese quartz movement (Caliber B620) and is rated water resistant to 100 meters (330 feet). It is secured with a perforated black leather strap, 22mm wide, fastened by a buckle clasp.
