Official description

One hundred years ago, Citizen changed the world of watchmaking forever with the launch of their first pocketwatch. Today, that legacy continues with the brand's latest Promaster Geo Trekker. Inspired by the patiently formed layers of Earth's crust, the new timepiece represents the unique embodiment of Citizen's watchmaking – using over a century of experience to pair meticulous design with incredible functionality.  

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.  

Underneath a scratch-resistant sapphire crystal, the watch’s data-driven, terra-inspired dial display is on view, with touches of greens, purples, and blues adding crystalline-like dimensionality alongside red and lume-filled details for enhanced utility. Towards the 6 o'clock position, a namesake northern hemisphere disc rotates counter clockwise, with the detail showcasing the world time with an old world map inspired design.  

Other standard and advanced functions of the watch include running hours and minutes, date indication, power reserve indication, world time, and a slide rule bezel function. This distinctive sports watch utilizes Citizen's Eco-Drive technology that’s sustainably powered by any light and never needs a battery. Water resistant up to 200 meters. Caliber H864.
