It is a "field composite band" model from PRO TREK's "climber line". A highly durable composite band of urethane and fine resin with metal inserted, lightweight titanium is used for the clasp, and a double lock clasp with a slide adjustment mechanism is also equipped. Increased durability and weight reduction reduce the strain on the wrist. In addition, the bezel, back cover, and clasp are IP-treated to improve wear resistance. Furthermore, using sapphire glass that maintains transparency, durability and outdoor visibility have been improved. In terms of functionality, it is equipped with a triple sensor Ver.3 that can measure direction, barometric pressure / temperature, and altitude, a tough solar that stably drives various functions, and a multi-band 6 that receives standard radio waves from 6 stations around the world and automatically corrects the time. However, it is equipped with functions that can be used in a wide range of situations, from outdoor activities to daily use.
