From the Nighthawk A-T collection, this men's Citizen Eco-Drive watch AT2187-51E is packed with features, all incorporated into an impressively stylish stainless steel design. Three sub-dials dominate the face of this design from Citizen watches and display the wide selection of additional functions. A combination of red and white detailing helps to make the different features stand out and luminescent coatings on the hands and batons retain light to make the watch easier to read in the dark. The dial is protected by scratch-resistant sapphire glass. This Citizen watch AT2187-51E includes a date window, perpetual calendar, day, chronograph, alarm, tachymeter gauge, charge indicator, alternate time mode, and radio-controlled time settings for five different cities across the world (London, New York, Chicago, Denver and Los Angeles). Like all Eco-Drive models from Citizen watches, this watch AT2187-51E is powered by light so it will never need a battery change. This mens designer watch is also 200m water resistant making it suitable for most water activities.
