Watch Overview

The Citizen World Chronograph A-T Blue Angels, reference AT8020-03L, is a distinctive men’s timepiece that combines advanced technology with bold design. Powered by Citizen’s Eco-Drive caliber H800, it runs on light and never needs a battery, while its atomic timekeeping ensures radio-controlled accuracy across 5 time zones and automatic time adjustment in 26 world cities. The blue dial features applied hour markers, luminous hands and indexes, a 24-hour subdial at 9 o’clock, a 60-minute chronograph counter at 12 o’clock, and a date window at 3 o’clock, all protected by an anti-reflective sapphire crystal. Housed in a 43 mm two-tone stainless steel case with a polished finish, the watch is fitted with a blue ion-plated bezel featuring a professional calculator scale and tachymeter, a screw-back case, and a leather strap. Water resistant to 200 meters (20 ATM), it also offers a perpetual calendar, 12/24-hour time, alarm, and power reserve indicator. Inspired by the precision of the U.S. Navy’s elite Blue Angels flight squadron, whose insignia is engraved on the case back, this chronograph blends functionality, durability, and style, making it a standout pilot’s watch ready for both adventure and everyday wear.
