With advanced technology paired with an incredibly bold look, the latest Promaster Air Navihawk reaches a higher altitude in style. The watch's silver-tone stainless steel case measures 40mm in diameter, wearing boldly with its sharp faceting and satin finishing, while a slide-rule scale on the dark gray bezel provides additional flight utility. A triple-link stainless steel bracelet secures the timepiece to the wrist.On the dial, a khaki green colorway with red, black, and white accents adds to the watch's superior legibility, while a sapphire crystal and 200m of water resistance protect it all. Functions include a 1/5 second chronograph measuring up to 60 minutes, 12/24 hour time displays, and a date indicator, all powered by our Eco-Drive technology – sustainably powered by light and never needing a battery. Caliber B620.
