National Geographic NG770C

 

 

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. You'll also enjoy automatic time calibration via radio signals, which get updated around every night. The silver watch case measures 43mm wide (1.69 inches) and is topped by a gray unidirectional bezel with coin-edged detailing for a firm grip under any condition. The brown dial is supplemented with a mix of silver bar and Arabic numeral hour markers, small minute indexes, luminous dagger-shaped hands. The dial also includes a digital window at the bottom that displays seconds and date. It's completed by a handsome triple-link stainless steel bracelet. Other features include a German-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.
