Take flight with the highly reliable, stylishly designed National Geographic Aviator men's stainless steel watch, which includes an integrated slide rule for quick calculations ranging from flight fuel consumption to currency conversion. The silver watch case measures 43mm wide (1.69 inches) and is topped by a black-plated unidirectional bezel with coin-edged detailing for a firm grip under any condition. The silvery gray dial is supplemented with a mix of silver bar and Arabic numeral hour markers, small minute indexes, and luminous dagger-shaped hands (with seconds hand). The dial also includes three subdials that show day and date as well as a second time zone. It's completed by a handsome triple-link stainless steel bracelet. Other features include a Japanese-made quartz movement, scratch-resistant mineral crystal and water resistance to 30 meters (99 feet)--enabling it to withstand splashes and accidental dunks into the water, but not suitable for swimming.
