Casio has launched a new all-metal G-Shock watch with a tough titanium case, earth-toned camo pattern, and a solar cell that keeps its battery topped up even in weak sunlight.

Watch batteries can be a real issue when you're travelling in the backcountry. Many of the best GPS watches can go several days or even weeks between charges, but unless you invest in a solar charger, you may find yourself suffering from range anxiety as the days wear on.

The new Casio G-Shock GMWB5000TVB1 doesn't have its own GPS chip to keep track of your location (for that you'd need a smartwatch like Casio's G-Squad Pro, which is powered by Google Wear OS), but its tough design and ability to extract all the power it needs from only a faint glimmer of sunshine make it a practical choice for life on the trails.

It also has Bluetooth connectivity, allowing it to link to Casio's G-Shock Connected app, which updates the time automatically four times per day. 

The GMWB5000TVB1's brown and dark gray ion-plated finish (which extends over both the watch's case and band) is achieved using a seven-stage process of masking, layering, and engraving. It's topped off with scratch-resistant sapphire crystal.

You also get all the usual features you'd expect from a G-Shock watch, including shock and drop resistance, water resistance to depths of 200m (twice as deep as most sports watches), five daily alarms, a countdown timer, stopwatch, calendar that updates the date automatically, and world time.

It will be available to buy for $1,700 (about £1,400) in July direct from, from the G-Shock store in Soho, and from third-party retailers.
