Citizen Promaster Geo Trekker Radio Controlled Eco-Drive BY3006-53H

The Citizen BY3006-53H Promaster Geo Trekker is a sophisticated aviation-inspired tool watch packed with advanced functionality. Its 46mm stainless steel case houses a data-driven gray dial with bold aviation-style markings, luminous hands and indices, and a rotating Northern Hemisphere UTC disc at 6 o’clock that provides an intuitive world-time display.

Built around Citizen’s H864 Eco-Drive movement, the Geo Trekker combines global radio-controlled timekeeping with 26 time zones, a perpetual calendar, 12/24-hour display, power reserve indication, and an aviation slide-rule bezel. Eco-Drive technology allows the watch to continuously recharge from virtually any light source, eliminating the need for regular battery changes.

A scratch-resistant, anti-reflective sapphire crystal and 200-meter water resistance give the Geo Trekker the durability to match its extensive functionality, while the solid stainless steel bracelet provides a refined, substantial feel on the wrist. Whether you're traveling across time zones or simply appreciate highly capable tool watches, the BY3006-53H brings serious functionality and distinctive Promaster styling together in one package.
