Citizen introduced the Promaster collection in 1989, consolidating their professional grade sports and tool watches under a single banner. The line was categorised into three specific environments: Sea, Land, and Sky. This approach provided dedicated instruments for divers, pilots, and mountaineers, building upon the company's prior developments such as the 1985 Aqualand, which featured the world's first electronic depth gauge.

The visual identity of the Promaster series is defined by its distinct dual arrow insignia. This emblem is designed to represent continuous forward momentum and the pursuit of technological progression. It is a functional mark, routinely stamped on the crowns, dials, and case backs of the collection, serving as a rapid visual indicator that the timepiece meets strict professional specifications for durability and environmental resistance.

Over the decades, the Promaster range has maintained a reputation for reliability in extreme conditions, heavily utilising Citizen's solar technology to ensure uninterrupted operation. The arrow logo remains a recognised symbol among professional operators and watch enthusiasts. This display piece accurately replicates the geometry of the insignia, offering a straightforward reference to a respected line of Japanese tool watches.

Approx 6" wide with a unique textured surface, this 3D printed model is made from high-quality, recyclable PLA, both lightweight and durable, making it an ideal display piece.
