It is a reality. Not long ago, we could still doubt whether the technology was intended to make the leap from our pocket to our wrists, but this is already a fact. Where once only time we found, on our watch, we can now also respond to emails, send messages via WhatsApp or Facebook, answer calls or even open our car (yes, we must first learn well how it works to save a shock). Soon we can leave our smartphones at home, or at least stored in the backpack, if we carry our the best smart watch. If all goes well, we will not have to wait long to do with these new devices, increasingly present on the wrists of the most geeky, everything we used to do with your mobile phone. Some predicts that the most prestigious watch companies must acclimate to the new times if you do not want to be drawn into oblivion. Others have other plans in mind. Knowing that end the prestigido Rolex, Swatch and Tissot will be complicated, and many do not want to get rid of jewelry so they have decided to try to convert old analog clocks in modern 'smartwatches' by changing the belt.   In fact, it was precisely the sector a prestigious brand which has opted more decisively by combining the expertise of the centuries-old Swiss watchmaking tradition and everything that technology can bring. The Montblanc company recently announced its e-Strap, a strap to attach the watch to your wrist incorporating a small screen that reflects the different notifications 'apps' installed in our 'smartphone'. As with most wiseupshop smart watches that exist today, e-Strap Montblanc still depends on mobile phone connection. Both devices are connected via Bluetooth (you can connect with Android and iOS devices) to reach us notifications on the screen watchband And not only that: it also allows you to interact with some of these 'apps'. With straps as this will not be necessary to remove the phone from the pocket if you're listening to music and want to move to the next song. It simply touching the screen of the e-Strap. In addition, the device developed by Montblanc incorporates an accelerometer to provide the necessary resources to the different applications that measure our physical activity daily data.   Kairos already tried his luck (and hit) Before Montblanc came to revolutionize everything, a company already thought of everything good move a 'smartwatch' to an analog clock through the belt. The Kairos firm presented a proposal as risky as successful. With the T-Band, its purpose was the same as that of the German company: get more out of this tool marks the rhythm of our lives changing only the strip of plastic, leather or metal that holds our wrist. As the e-Strap, the band Kairos tells us if we have received an email, if we have a call to answer or makes us aware of our vital signs. Even, and according to its creators, it could become the instrument that will eventually replace the keys to our car.
