The PRT-B50 is equipped with a smartphone link function in addition to a quad sensor that can measure four points: direction, barometric pressure / altitude, temperature, and number of steps. Lightweight and rust-resistant titanium is used for the band material, making it suitable not only for outdoor scenes but also for everyday use. Black IP treatment is applied to the band, and the liquid crystal part of the case and dial is also black. By finishing with a black-based monotone, high visibility and a fearless design have been achieved. Large Arabic characters are placed on the three-dimensional dial to improve visibility. Combined with metal parts, it has a valuable finish. A lightweight and strong glass fiber-filled fine resin back cover and a button guard to prevent button malfunctions enhance the robustness of the watch. The large rotating bezel that can be operated while wearing gloves gives a wild and strong impression.
