The internet of things or IOT revolution is happening right now, and by year 2020 according to tech analyst firm Linley Group, there will be tens of billions of devices connected to the internet. These devices can communicate, learn users’ behavior — and change the way humans live and work in this tiny speck of the cosmos. So it shouldn’t surprise anyone that one startup is trying to transform all watches into smartwatches. Chronos is not a smartwatch, but it’s a device that can turn an old Rolex watch into a semi-smartwatch that can sync with a smartphone, either an Android or an iPhone. Chronos is a small metal disc made of 316L grade stainless steel, with a polycarbonate window for light notifications. It’s just 3mm thin and 3mm in diameter, and it can fit on 80 percent of watches in the market today. It offers bluetooth 4.0 low energy integration, 36-hour battery life, wireless charging, accelerometer, haptic vibration, LED notifications and water proof design.
