Atomic Timekeeping AT8304-57A

Purpose takes flight with the Promaster Navihawk A-T, the latest addition to our professional Promaster Air collection. Measuring 41mm on the wrist and water resistant up to 200 meters,... the flight-ready timepiece is a mission-focused powerhouse, featuring a sturdy construction in gray ion-plated stainless steel with a sharply finished triple-link bracelet and two bold crowns to match. On its pilot-style dial, high-performance luminous hands and markers contrast against a gray background for quick legibility. An aeronautical slide-rule scale surrounds the display and is operated by a 7 o'clock crown, while a 3 o'clock date window showcases daily utility. Other advanced features include world time in 26 time zones, a perpetual calendar with day and date indicators, 12/24-hour timekeeping, and a power reserve display. Featuring Eco-Drive light-powered Atomic Timekeeping functionality, the radio-controlled timepiece self-adjusts its time or calendar when traveling overseas by receiving local time signals in four different regions.
