Powered by light, the Men's Blue Angels Skyhawk A-T Chronograph Rubber Strap Watch from Citizen Eco-Drive is , chock full of features, and comfortable enough to wear every day. This rugged timepiece features atomic time keeping, (automatically set by signals from North America, Europe and Asia), and offers a GMT (Greenwich Mean Time) display, world time with 43 cities, and two alarms. A 1/100 second chronograph measures up to 24 hours, and there's also a 99 minute countdown timer, perpetual calendar, and rotating slide rule bezel. For protection against damage, a non-reflective, hardened mineral crystal guards against scratches. And a blue dial with silver-tone hands and markers and digital display looks sleek and modern, while a rubber strap feels secure and relaxed on the wrist. Designed for long-term wear, this Citizen Eco-Drive original arrives in a gray box, along with a manual, and information CD.
