Engineered for easier and faster setting, the Roadmaster Marine GMT by BALL Watch Company features quick-set GMT push buttons that revolutionize the way the GMT hand is adjusted.
Simply by turning and pressing either one of the patented quick-set buttons, the GMT hand can be easily set instead of using the main crown.
The button at 8 o’clock moves the GMT hand backward, while the 10 o’clock button moves it forward. Combined with a bi-directional 24-hour bezel and main hands, the Marine GMT allows for three time zones to be tracked simultaneously.
In the darkest conditions, time can be read thanks to the self-powered H₃ gas tubes used by BALL. This cutting-edge Swiss technology consists in encapsulating H₃ gas in glass micro tubes. Light energy is released when the H₃ molecules strike the internal colored surface of the tubes. This phenomenon doesn’t require recharge from any external light or energy source. The 28 tubes are carefully mounted onto the dial at each hour marker as well as the main hour hand, minute hand and GMT hand.
The markers at 6, 9 and 12 o’clock are shaped as Arabic numerals forming one of the most iconic BALL dial designs. In combination with the ceramic bezel’s Super LumiNova coating, the three time zones can easily be read in total darkness.
The Marine GMT features the chronometer certified automatic caliber BALL RR1203-C with day-date functions. It is water resistant to 200m/660ft, anti-magnetic to 4,800A/m and shock resistant to 5,000Gs.
Its case is made of titanium while its bracelet combines stainless steel and titanium parts. The movement can be admired thanks to a see-trough case back and the crown screws in for better resistance.
This 40mm Roadmaster Marine GMT watch model is available in several harmonious color variations. It comes on a bracelet but can also fit a rubber or NATO strap.
