One hundred years ago, Citizen changed the world of watchmaking forever with the launch of their first pocketwatch. Today, that legacy continues with the new limited-edition Promaster Geo Trekker. This timepiece features global Radio Control timekeeping for exceptional accuracy and a dial inspired by the geological layers of Earth’s crust, made of recycled materials using a structural color ink developed by FUJIFILM Corp. This innovative ink creates a spectrum of hues and tones with a sense of depth through light reflection, thanks to Eco-Drive technology that utilizes light as a clean energy source to measure the passage of time.

 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 counterclockwise, 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 our proprietary Eco-Drive technology that’s sustainably powered by any light and never needs a battery. Water resistant up to 200 meters. Caliber H864.
