The watch is in Citizen’s famous Eco-Drive category, meaning that the face containing solar cell. Wearing the watch in daylight keeps the batteries charged for several months. It’s basically a zero-maintenance watches no batteries, no winding, etc. You can’t even tell the face is a solar cell — it appears solid black, even up-close. The styling is both eye-catching and subtle, and you can wear it with almost anything — a shirt and tie, a t-shirt, a swimsuit, etc. Citizen watches are relatively affordable and offer a great deal of reliability for the price. There are no gimmicky diving bezels or anything of the sort. The entire watch’s case is devoted to the large face and the small but still usable circular slide rule. It is in 46 mm diameter and 13 mm thick. It appears much bigger than it really is because of the big face and lack of diving bezel. You get a screw-down crown at 3 o’clock and a crown to adjust the slide rule at 8 o’clock.
