A PRO TREK model that improves outdoor usability by connecting to the specific CASIO WATCHES application via Bluetooth®. It has a quad sensor capable of measuring the number of steps, orientation, altitude/barometric pressure and temperature. It records the calories burned, the altitudes obtained by the watch and the routes obtained through the smartphone's GPS in the application.

Automatic time adjustment is carried out worldwide through the simplification of various settings. It can also automatically correct the altimeter and calculate sunrise and sunset times. In addition, it allows you to activate or deactivate modes and enjoy customization by changing the screens of the application.

The fine resin back cover uses a structure that integrates with the lugs. Both the button protection and the case have been made more resistant. The wide dial uses Arabic indexes to ensure high visibility.

Metal parts are used for the orientation indicator and colors reminiscent of the outdoors are used as details. In addition, the entire surface of the urethane strap has a 3D texture to prevent the strap protector from slipping, improving ease of use in outdoor environments.
