Promaster Geo Trekker. One hundred years ago, Citizen changed the world of watchmaking forever with the launch of their first pocketwatch. A bold 46mm stainless steel case in a dark gray tone centers the design, with the professional-grade pilot’s watch mission-ready on the wrist, fully equipped with a bold set of chronograph pushers, 5-link steel bracelet, and an outer slide rule bezel.
