Casio Pro Trek Smart WSD-F20: Rugged smartwatch sequel essential guide

GPS finally lands for Casio's Wear range - here's all you need to know

The Casio WSD-F20, the Japanese company's second stab at the Android Wear market, was announced back in January and now the Wear 2.0-toting smartwatch is finally up for grabs.

The successor to the Casio Smart Outdoor WSD-F10 now falls under the company's Pro Trek Smart Series and delivers the feature we wanted most from the original: built-in GPS.

Wareable verdict: Casio WSD-F20 review

Read on to find out everything you need to know about the Pro Trek Smart...

Casio WSD-F20: Design and display

Casio's new smartwatch is still built for ruggedness and thankfully the watch specialist has managed to pack in everything without adding any extra bulk.

Measuring 61.7mm √ó 56.4mm √ó 15.7mm, it weighs the same 92g as the original.

It's still water resistant to 50 metres as well and it's been built to military standards (MIL-STD-810) so it can handle a bit of rough and tumble.

Available in orange or black, you'll find the same 1.32-inch dual layer LCD 320 x 300 touchscreen display that jumps into monochrome mode when you're running low on battery. That battery life is roughly the same as before giving you a day's play with everything running, and a month if you're just using it in normal watch mode.

Casio WSD-F20: GPS and sensors

As far as sensors are concerned, you'll still get pressure (air and altitude), accelerometer, gyrometer and magnetic compass sensors. This should help you in tracking a host of different outdoor activities including trekking, cycling, fishing, winter sports, and water sports.

The big addition though, as mentioned, is GPS. Casio says the WSD-F20 features low-power GPS and will offer compatibility for Glonass and Michibiki satellite systems to improve tracking further. Along with support for colour maps, it's much better built for adventurers. For instance, it now supports the ability to download maps offline so you can trek and not get lost without relying on a data connection.

The onboard GPS also unlocks more features including GPS-based watch faces (think altitude and compass widgets) and a nifty sounding Location Memory feature - built in tandem with Mapbox.

This instantly reads the user's location and lets you lay markers by hitting one of the physical buttons on the side of the watch. You can leave voice notes using the built-in mic if you want to revisit an old spot and the W20 also improves activity tracking, particularly for snow sports to deliver additional data like maximum speed for each run.

Casio WSD-F20: Android Wear 2.0 and apps

The Casio Pro Trek Smart is compatible with Android phones and iPhones running iOS 9 or above, and Google is running the software show once again. The good news is that the WSD-F20 has Android Wear 2.0 out of the box. The original WSD-F10 has already been upgraded to the latest version of Google's operating system as well.

While you'll get to benefit from all of the new Wear features including standalone apps, Casio has a bunch of its own applications that are designed for adventurers as well third-party apps that make use of the its features. That includes ViewRanger, MyRadar and Yamap for hiking.

In terms of its own apps, there's Moment Setter that sends alerts to the user, whether that's a reminder of the best fishing times or sunrise/sunset times. The Tool app uses the host of sensors to deliver real-time information on changes in the natural environment including altitude or air pressure.

A new Casio Moment Link app can display the current location of a group of friends on the display letting you communicate through text messages. This obviously requires the GPS and will apparently be an Android only feature. Sorry iPhone owners.

Casio WSD-F20: Price and availability

    I wish Casio would also introduce a proper G SHOCK Smartwatch that is shock resist, with water resistance upto 200m, and most importantly: Name it G SHOCK

    • Big_O·

      From the looks of the watch I thought it was a G-Shock! I got all excited but this watch still looks kick ass. I'm sure they'll introduce their newer model as a G-Shock with all of those awesome features.

        The MIL-STD-810 is a big deal.  Especially since this watch is shock proof, waterproof, dust proof, temperature tested in both high and low temperatures.   Including icy conditions.   Also it has strong steel construction.   So you could almost use this smart watch to hammer in nails.   Not to mention the 1 day is with the watch face on all the time.   So if you want to get 2-3 days then turn off ambient mode, WiFi, GPS.   If you only want the time then a month is not bad at all.


      Well that will be tough because this is a Protrek line watch, which is better than G-Shock. I know G Shock sounds soooo much more sexy...

  • Nischit·

    Just imagine how many people will buy it then!

    • Sgodsell·

      It is shock proof.   It is MIL-STD-810G.   So it definitely is shock proof, including dust proof.  Even tested in icy and hot damp or dry conditions.   Look up the military testing standards.

    No mention of the flat tire on the screen? Other than that it looks great. A full day running sensors (I assume this includes GPS) or a month in just watch mode is incredible. Hope it's true.

    If they only release it in Japan and the US like the previous model, it will be pointless. I wanted one of the originals but being in the UK it wasn't worth it. Bought a Garmin Fenix 3 instead. Great watch with battery life the Casio can only dream of. And I'm not a Casio hater. I have an Edifice and 2 G-Shocks

      Just get it from Germany. It's much cheaper than in the UK.

    This report is a little thin and does at no point go over what is presented on the casio product website. Own content/experiences would have been more helpful! Disappointing!

    well i have the watch for the last three days.     Poor battery life nearly dead by 3 pm in afternoon and then I cant use for my runs that afternoon until charged (no fast charge).  the battery cords connects by magnet which is very weak and just falls off by walking by it. For  so many functions the directions  are terrible. I expect battery would not last through a long run on trails through mountains. I like all the functions available on the watch.  


      Turn off the always on display. Also what watch face are you running? If you run one with 20 things pulling data it will run it down. I have 4 smart watches, they all are the same with power, except the Garmin (Fenix) because of it's screen is reflective, great outdoors, not so good indoors. I get about 20 hours of a busy day with my F20 now. I agree on the battery cord, wish it had a charging stand. Then everyone could complain about having to travel and pack a stand. Wondering if Casio's tough solar will ever be used???
