Citizen Automatic Promaster Air GMT NB6045-51H


Purpose takes flight with the Promaster Air Automatic GMT, the latest addition to our professional Promaster Air collection with new mechanical movement. Measuring 44.5mm on the wrist and water resistant up to 200m, the new flight-ready timepiece is a mission-focused powerhouse, featuring a sturdy construction in gray ion-plated stainless steel with a 24-hour bezel and two bold crowns to match. On its pilot-style dial, high-performance luminous hands and markers contrast against a black 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 and red-accented GMT hand showcase daily and travel utility. Inside the new Promaster Skyhawk is the Citizen Caliber 9054, a reliable automatic mechanism featuring a 50-hour power reserve, accurate to -10 / +20 seconds per day, and magnetically resistant up to 16000 A/M.
