Citizen Promaster Eco-Drive Geo Trekker Air BY3005-56E

A century ago, Citizen revolutionized watchmaking with the launch of their first pocket watch. Today, that heritage lives on in the latest Promaster model. Drawing inspiration from the layered formation of the Earth’s crust, this timepiece perfectly blends over 100 years of craftsmanship with exceptional design and functionality. Featuring a bold 46mm dark grey stainless steel case, the professional-grade pilot’s watch is built for action, equipped with prominent chronograph pushers, a durable 5-link steel bracelet, and an outer slide rule bezel.

Protected by a scratch-resistant sapphire crystal, the dial showcases a data-rich, earth-inspired design highlighted by shades of green, purple, and blue that create a crystalline depth, accented with red and luminous details for enhanced readability. At 6 o’clock, a rotating northern hemisphere disc moves counterclockwise, displaying world time over an old-world map motif. Key functions include running hours and minutes, date display, power reserve indicator, world time, and slide rule bezel operation. Powered by Citizen’s Eco-Drive technology, this watch charges sustainably from any light source and never requires a battery. Water resistant up to 200 meters, powered by Calibre H864.
