There’s a whole range of smartwatches on the market, from the Apple Watch to the latest LG Watch Sport. They all have a few things in common: crappy battery life, delicate screens, and complex interfaces. Certainly smart watch features and apps are appealing, but for most people a watch is primarily for telling the time. That’s where the Casio Edifice range steps in – they are all about being a watch first and using your smartphone as the accessory.

I’ve been wearing the Casio Edifice EQB-600D for the past few weeks to see how it works. It’s not a discrete watch, but its stainless steel finish is more classy than the Casio G-Shock range. I’m still undecided about how it looks. There are many positives  – the polished bezel, the chunky buttons and the striking 3D Globe Dial – but it’s a little showy for my taste. But these things are very personal and I’ve certainly received lots of positive comments about it – more so than my usual Huawei Android Wear watch.

The Casio Edifice EQB-600D is made from polished stainless steel and features a large chronograph display and four complications: World time, Day, Date and the 3D Globe Dial. These sit underneath a mineral glass face that should protect you from minor scrapes. Of special note is the 3D Globe Dial that rotates to show the areas currently in daytime & nighttime. If that’s not impressive enough, the Tough Solar technology charges your watch whenever it’s exposed to light. I double-taked when I first realised that the watch was solar, the face looks nothing like solar panels that I’ve seen before – this just looks like a regular watch.

Surrounding the bezel are four buttons, three on the right and one on the left. Starting on the right hand side, the top button switches the main dial to world time, the lockable crown sets the time, and the lower button triggers the phone finder. The left-hand button initiates the Bluetooth connection to your handset.

Apart from the looks, there’s a lot going on inside the Casio Edifice EQB-600D. The main benefit is the Bluetooth link that connects with your smartphone. This allows for simple setup of the watch as well as some useful extra features. You perform all these functions through the Casio Watch+ app that guides you through linking your watch and smartphone. Once this is done, you can adjust the time, set favourite timezones, change summer time settings and set up the phone finder. This is particularly useful if you leave your phone lying around – just press the lower-right button on the Casio Edifice and your phone starts to ring after a few seconds.

The app also includes a guide to the watch’s features and a handy battery gauge to see when you next need to find some sunlight. If the battery gets too low, the app will alert you with a notification. All you need to do is put it back in the sun (or under a lamp) and the watch recovers back to its former self. Other features worth mentioning are the 100m water resistance, automatic daylight savings changes and the luminescent dial.

Overall I’ve found the Casio Edifice EQB-600D to be an interesting take on the smart watch. It won’t keep you up to date with notifications, but the few features it has work well. The Bluetooth link worked flawlessly during my testing and kept the time perfectly syncronised. But the main attraction is the battery life which is almost infinite. As long as the watch sees some light on a daily basis you shouldn’t have to think about charging it. This is a far cry from most smartwatches and is a great addition by Casio.

If you’re not in the market for a charge-every-day smartwatch but see the benefits in a smarter-watch then the Casio Edifice EQB-600D could be for you.
