Last year it was the WSD-F20, this year it’s the WSD-F30. Casio’s latest and greatest Pro Trek builds on its predecessor’s success and fine-tunes some of the more disappointing aspects, resulting in a timepiece that really does vault the Pro Trek family into the future

.

One such let down from the WSD-F20 was the battery life. To combat this, Casio is now offer what they’re referring to as Extended Mode. What this does is strip the watch back to the basic monochrome display that only shows the time and measurement data. GPS tracking is still enabled, however, and colour maps can return any time at the touch of a button. The biggest battery-saving leap of all, though, is the new Multi Timepiece Mode. This still makes the display monochrome and you can no longer connect to a smartphone, but access to the watch’s sensor, such as the ones for atmospheric pressure and altitude, is still available on the black and white display. Even while doing all this, you’ll still be able to get a month’s battery life out of the WSD-F30.

A further upgrade from the previous model is the display. While it’s still dual-layered, this time the LCD display has been replaced by an OLED one. The WSD-F30 is also the thinnest in the series yet, retaining legendary Casio outdoor watch toughness while being 3.9mm narrower and 0.4mm thinner than the WSD-F20.

By running Google’s Wear OS, the watch gives you full access to Google Assistant. Nowadays, there’s little that this feature doesn’t do, with the highlights being using voice control to navigate whilst driving; replying to texts, and controlling smart home devices. As well as this, there’s also access to a whole host of Wear OS apps. By working with a number of partners, Casio has been able to offer things such as sports specific tracking information, turning the latest Pro Trek into a fully-fledged golf rangefinder.

A significant and needed improvement on what’s  gone before, the WSD-F30 is due to be released in January  2019 and is likely to cost around £450 to £500.
