The Roadmaster Marine GMT is a watch designed by the BALL Watch Company, aimed at adventurers who need a reliable and technically advanced timepiece. The watch features a quick-set GMT function with push buttons that make adjusting time zones easier and faster. By using the button at 8 o’clock, the GMT hand can be moved backward, while the button at 10 o’clock moves it forward. This, combined with a bi-directional 24-hour bezel and main hands, allows for tracking three time zones simultaneously.

For readability in darkness, the watch uses self-powered H₃ gas tubes. This Swiss technology encapsulates H₃ gas in glass micro tubes, releasing light energy without needing an external light or energy source. The watch has 28 tubes on the dial, including the main hour hand, minute hand, and GMT hand, with Arabic numerals at 6, 9, and 12 o’clock. The ceramic bezel’s Super LumiNova coating ensures the time zones can be read in total darkness.

The Marine GMT is powered by the chronometer certified automatic caliber BALL RR1203-C, featuring day-date functions. It is water-resistant to 200m/660ft, anti-magnetic to 4,800A/m, and shock-resistant to 5,000Gs. The case is made of titanium, and the bracelet combines stainless steel and titanium parts. The movement is visible through a see-through case back, and the crown screws in for added resistance. This 40mm model comes in several color variations and can also be fitted with a rubber or NATO strap.
