As seen at CES 2015, the iSetwatch is not just a smartwatch that is equipped to improve your fitness, it can also be used to score tennis matches in real time -- right from your wrist. Described as the first smart tennis counter, the tennis watch is perfect for practice.
The iSetwatch has Bluetooth technology, allowing it to connect to other iSet tennis watches or to an accompanying app. The smartwatch lets you share scores live, analyse your tennis performance and has an e-referee function. This is all in addition to more general features such as an alarm, all purpose timer, countdown timer and stopwatch. Of course, it also works as a regular time-keeping clock. The athletic waterproof watch comes in six colors too.
