Meet the Citizen Eco-Drive Tank Watch for men—a refined rectangle silhouette that pairs a bold black dial with a timeless gold-tone finish. The 31mm gold-tone stainless steel case sits proudly on a polished bracelet, delivering a versatile look that transitions from formal to casual with ease.

Powered by Citizen's Eco-Drive solar technology, this watch charges from any light source and runs on energy stored in a rechargeable cell—so you never need to worry about replacing a battery. The 12-hour dial with central second hand ensures precise timekeeping, while a durable mineral crystal protects the face from everyday wear. A fixed gold-tone bezel completes the sophisticated, enduring style.
