On the wrist, 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 blue ion-plated bidirectional bezel provides additional flight utility. A triple-link stainless steel bracelet secures the timepiece. On the dial, a Blue Angels colorway with 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. The movement is protected via a Blue Angels’ insignia-signed case back, and is powered by Citizen’s Eco-Drive technology – sustainably powered by light and never needing a battery. Caliber B620.
