Casio’s PRO TREK smart watch series has a new addition to the family. The WSD-F30 comes with an extend mode which enables use of offline colour maps and GPS for up to three days on a single charge. In extend mode time and measurement data is continuously shown on the monochrome display, and a colour map can be displayed with the push of a button. Extend mode also conserves energy by switching the operating system to energy-saving standby mode on a schedule set by the user.

The inner components have been rearranged to make the case thinner for a more compact profile, and the wristband has been improved and is now more flexible and with more holes for greater adjustability and fit.


  • New improved Dual layer display
  • Smaller, thinner case
  • Extend mode allows use for up to three days offline
