A "PRO TREK" model with enhanced outdoor possibilities thanks to Bluetooth® connection with the special "CASIO WATCHES" application. Quad-sensor capable of measuring number of steps, direction, altitude, atmospheric pressure and temperature. Records in the app calories burned, altitudes reached by the watch and routes recorded via smartphone GPS. The simplification of various settings enables the watch to adapt automatically anywhere in the world. The watch also automatically corrects the altimeter and calculates sunrise and sunset times. What's more, you can activate or deactivate modes and personalize your watch by modifying the displays via the app. The fine resin back features a structure that integrates with the fins. Both the button protection structure and the case are more robust. The large dial features Arabic hour markers to ensure good visibility. Metallic parts are used to indicate the hands, and colors reminiscent of the outdoors serve as accents. What's more, the entire surface of the urethane strap has a 3D structure that prevents the strap from slipping, thus enhancing its suitability for outdoor use.
