While Casio has always been ahead of the game when it comes to wearable tech, the G-Shock GSTB100XA-1A G-Steel comes with a lot of cutting edge advancements. For example, it uses Bluetooth low energy (BLE) technology to network with your smart phone via the G-SHOCK connected app. BLE lets smartphone users experience richer, more interactive connections beyond the mobile handset while using less power. Another difference between many smart watches and the GSTB100XA-1A is that even when youre connected, you can quickly switch back to time mode at the press of a button. And it will accurately update you no matter where in the world you may be. And because short battery life and having to carry around all kinds of charging devices is a hassle, a big advantage of the GSTB100XA-1A is that it uses solar-powered charging capabilities. And it comes with and a super LED light for maximum visibility in the dimmest of situations. This latest Connected model is not only a mix of wireless technologies, it is also a showpiece of an alchemy of materials. The GSTB100XA-1A comes outfitted in a black and silver colorway that features a black and blue and blue, layered band, a multi-dimensional carbon bezel and a solid sapphire crystal. And while carbon makes for a great look, the combination of Toray Industries state-of-the-art TORAYCA and NANOALLOY materials also provides extra shock resistant capabilities. Did we mention that it looks great The G-Steel line is one of the G-Shock collections designed with the gentleman in mind. It looks as good paired with a suit as it does with a more relaxed weekend casual cardigan. And with a newly slimmed down 53.8mm case size, it still has a lot of wrist presence without getting all caught up in your shirt cuffs.
