Citizen's Promaster line was built for adventures that go beyond the city. The Altichron BN5058-07E combines a light-powered Eco-Drive movement with an electronic compass and an altimeter that reads from 1,000 feet below sea level to 32,000 feet above it. A 47 mm black ion-plated steel case, luminous black dial with orange accents and polyurethane strap complete the watch, which is water resistant to 200 meters.
