Ca­sio ProTrek Smart WSD-F20

A smart­watch for hik­ers

HWM (Singapore) - - CONTENTS - By James Lu

The Ca­sio WSD-F20 is Ca­sio’s sec­ond An­droid Wear smart­watch, fol­low­ing the WSD-F10. The big­gest dif­fer­ence be­tween the two is that the WSD-F20 now has built-in GPS track­ing. The WSD-F20 looks quite sim­i­lar to its pre­de­ces­sor with a round 1.32-inch 320 x 300 pix­els res­o­lu­tion dis­play and a re­ally chunky bezel. The screen isn’t that big, but the mas­sive bezel makes the watch much larger than most other smart­watches. The screen is a dual-layer LCD panel, which means that when the watch isn’t in use, it switches to a sim­ple mono­chrome trans ec­tive dis­play, which also helps to save bat­tery power. To take ad­van­tage of all of the watch’s sen­sors, Ca­sio has also added a few cus­tom watch faces to the WSD-F20 in­clud­ing ones that con­stantly dis­play your alti­tude, dis­tance trav­elled and air pres­sure.

The dis­play it­self is re­cessed from the bezel, which gives it some pro­tec­tion from scratches and drops, and the en­tire watch is certi ed to MILSTD-810G stan­dards, which en­com­passes a whole se­ries of mil­i­tary­grade test con­di­tions for tem­per­a­ture, pres­sure, shock im­pact and more. A rar­ity among An­droid Wear smart­watches, the WSD-F20 is also water-re­sis­tant up to 50 me­ters, or ve

at­mos­pheres of pres­sure, which means you can wear it while swim­ming.

On the right-side of the watch you’ll nd three but­tons. In the mid­dle is the stan­dard An­droid Wear but­ton, which lets you tog­gle be­tween the apps menu and watch face. The top but­ton launches the Tools menu, which is unique to the WSD-F20, while the lower but­ton launches a ded­i­cated lo­ca­tion-track­ing app.

Ca­sio does rugged smart­watch right with An­droid Wear 2.0 and built-in GPS, but it’s still a niche de­vice.

In the Tools sec­tion, you’ll see why the WD-F20 falls un­der Ca­sio’s ProTrek brand. There’s an ar­ray of in­for­ma­tion here ded­i­cated to hik­ing and out­door sports, in­clud­ing an al­time­ter, barom­e­ter, a clock show­ing the sun­rise and sun­set times, a com­pass and an in­di­ca­tor of the day’s tide lev­els.

Press the lower but­ton and you’ll launch the lo­ca­tion-nder app, which uses the watch’s built-in GPS to show your cur­rent lo­ca­tion. As you of­ten won’t have Wi-Fi or even a 3G con­nec­tion while you’re out hik­ing, this app can ac­tu­ally use pre-down­loaded map data to dis­play maps oine. You can tag lo­ca­tions you’ve vis­ited and add voice notes and memos to them.

Ca­sio hasn’t re­vealed the pro­ces­sor in­side the WSD-F20, but a sys­tem scan shows it to be a dual-core Cor­tex-A7 CPU, run­ning at 1GHz (which likely makes it the Me­di­aTek MT2601). While that gives it only half the cores and a slower clock speed than Qual­comm’s Snap­dragon Wear 2100, used in a num­ber of other An­droid smart­watches, the WSD-F20 didn’t lag or strug­gle with any of the apps I in­stalled on it.

Ca­sio also doesn’t pro­vide de­tails re­gard­ing the bat­tery spec of the WSD-F20 but it gen­er­ally will last about one day on a full charge. Turn­ing on GPS and ac­tively track­ing a route does how­ever cause the bat­tery to drain alarm­ingly fast. When you do need to charge the watch, it uses a sim­ple mag­netic charg­ing plug that con­nects with a port on the side of the watch. Un­for­tu­nately, it’s quite easy for it to be­come ac­ci­den­tally dis­lodged.

It’s denitely not your ev­ery­day smart­watch, but with oine maps, built-in GPS, an ar­ray of sen­sors and a MIL-spec, wa­ter­proof build, the WSD-F20 will be one of the best smart­watches for any­one that spends a lot of time out­doors.

Snap-on mag­netic charg­ing port on the side of the watch is handy, but prone to dis­lodg­ing be­cause of the cable de­sign.

The watch has a chunky bezel and a re­cessed screen to pro­tect the dis­play from scratches.

The side but­tons give you quick ac­cess to hik­ing tools and your GPS lo­ca­tion.
