An exciting addition to the Promaster Air collection with a new mechanical movement. The Promaster AIR Automatic GMT measures 44.5mm on the wrist and is water resistant up to 200m, this flight-ready timepiece is a mission-focused powerhouse, featuring a sturdy construction in grey ion-plated stainless steel with a 24-hour bezel and two bold crowns to match. On its pilot-style dial, a 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 GMT hand showcase daily and travel utility. Inside the new Promaster AIR is the Citizen calibre 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
