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 colour 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 grey tone centres 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 metres. Calibre H864.
