A PRT-B50 equipped with a smartphone link function in addition to a quad sensor able to measure number of steps, direction, altitude/barometric pressure, and temperature. Lightweight and rust-resistant titanium is used for the band material, making the watch suitable for everyday use as well as the outdoors. The monotone colour scheme is accented by colouring the second hand and the letter "N," indicating north, on the large rotating bezel, orange. Large Arabic characters are included on the three-dimensional dial to improve visibility.

This combines with the metal parts to create a finish that exudes a sense of value. A lightweight, strong glass fiber-infused fine resin back cover and a button guard for preventing button malfunctions make the watch more robust. The large rotating bezel that can be operated even with gloves on gives a wild, strong impression.
