Unlike most smartwatches that uses induction charging, WSD-F30 uses a charging cable to plug to the watch. The charging port located on the left of the watch is magnetic, so it will snap into place.

Despite being small in size, the USB charger has to be connected to a bulkier power cord to work. Casio should have just included a USB wall charger instead.

I am not a fan of the WSD-F30 charging method. It looks ugly and because of its protruding nature, you will accidentally knock the charging cable off from the watch. The magnet is not very strong.

Battery Life
If you are only using monochrome display without GPS, Wi-Fi, or Bluetooth, it can last you about a month.

A mixture of both color and monochrome (default), without Wi-Fi or Bluetooth, can last you about three days. This mode is useful for three days/two nights tracking.

And lastly, with color and all the features turn on, it will last you about 1.5 days.

There are three buttons on the watch and all of them are located on the right. The top button is the Map button. Pressing it shows where you are right now.

WSD-F30 is designed for extreme sports, and hence it conforms to the MIL-STD-810G standard for durability established by the U.S. Department of Defence.

Water resistance of the WSD-F30 is up to 50m. So you can swim with it or go snorkeling with it, but you can’t Scuba dive with it.

One of the unique features of the WSD-F30 is the 1.2″ dual-layer display. It has both a monochrome and a color display.

For color, it uses an organic Electroluminescent (EL) display which has a higher resolution (390 x 390) than its predecessor.

For monochrome, besides the time, it also displays the atmospheric pressure/altitude and compass bearing.

For other apps, Casio’s partners’ design most of the Wear OS apps for Pro Trek smartwatches.

The apps are not exclusive, just that they are designed for Pro Trek smartwatches in mind with the use of the watch’s dedicated buttons.

Some notable apps include:

  • ViewRanger: This GPS mountain-climbing and trekking app allows users to check route guides, maps, navigation, and their progress. Users can plot waypoints to create their own original courses.
  • Bikemap: This app contains map data for over 3.4 million biking routes in 80 countries around the world.

    at the gym or at home.
  • MyRadar: This helpful weather information app predicts the weather by displaying an animated depiction of weather changes in the surrounding area.

The WSD-F30 is targetted at people who love outdoor and extreme sports due to its shock resistant.

I am probably not their target audience since I don’t do both.

Wear OS does work on iOS devices, but the functionalities are limited. I still recommend user to use Android for Wear OS.

If you are on the iOS ecosystem, Apple Watch is probably a better choice. But sadly Apple Watch is not shock resistant.

The WSD-F30 is not meant to compete with the Apple Watch but with Garmin’s Fenix 5X and Suunto’s Traverse Alpha.

Despite the high price, WSD-F30 doesn’t include a heart rate monitor which is quite disappointing.
