Celebrating 35 Years of Innovation: Introducing the Citizen Promaster Geo Trekker

The Citizen Promaster collection, renowned for its purpose-built tool watches, marks its 35th anniversary this year with a spectacular addition. As part of the ongoing celebration, Citizen unveils the Promaster Geo Trekker, a rugged radio-controlled world timer powered by the innovative Eco-Drive Cal. H864 movement. Let's delve into the features and design of this exciting new timepiece.

Design and Variants

Crafted from durable stainless steel, the Promaster Geo Trekker debuts in two distinct colorways. The ref. BY3006-53H boasts a standard brushed finish, while the ref. BY3005-56G features a sleek dark gray coating. The dial colors correspondingly align with their finishes, with the BY3006-53H showcasing a dark gray dial and the BY3005-56G sporting a black dial with red accents, enhancing its tactical appeal. Both variants come with stainless steel bracelets, combining brushed and polished surfaces for a cohesive look.

Dimensions and Construction

Measuring 46mm in diameter and 11.5mm thick, the Geo Trekker features a slightly conical profile that maximizes dial space without overwhelming the wrist. The flat sapphire crystal with anti-reflective treatment ensures durability and clarity. The bezels, resembling aviation scales, add a distinctive touch and hint at the watch's functionality for aviation enthusiasts.

Functionality and Movement

Flipping the Geo Trekker reveals a solid stainless steel caseback adorned with a map of the Northern Hemisphere. The watch is equipped with a screw-down crown, pump-style pushers, and boasts water resistance up to 200 meters, making it suitable for various environments. Powering the Geo Trekker is the advanced Cal. H864 Eco-Drive movement, offering radio-controlled timekeeping, a perpetual calendar, power reserve indicator, and world timer functionality.

Dial Details

The dial of the Geo Trekker is information-rich, featuring three registers, multiple scales, and a date window. A rotating UTC disc at 6 o’clock displays world time, complemented by a multi-function register for day display and a sub-dial for AM/PM indication. The font and design elements on the dial draw inspiration from historical navigation charts, enhancing its adventurous spirit.


The Citizen Promaster Geo Trekker exemplifies Citizen's commitment to modern timekeeping, blending analog elegance with advanced functionality. With a price range starting at $795 USD, this timepiece offers a compelling option for enthusiasts seeking both style and utility, bridging the gap between traditional and digital watches. It's a testament to Citizen's enduring legacy of innovation in watchmaking.
