Diesel On DZT1013 Hybrid Smartwatch - you would think a robust men's watch. But as an extra, the watch has various smartwatch functions. The watch may not have a touchscreen, but many functions correspond to a full-screen smartwatch. The watch keeps track of your steps, gives you notifications, and with just the push of a button you can either control your music (switch tracks, determine start / stop or volume), take photos, view your alarms or the date! A nice advantage of a hybrid smartwatch is ... you do not have to charge the watch daily. You can easily install a CR2430 battery yourself. You can download the 'Diesel On' app from the Google Playstore or Apple Appstore. With this app you connect your Android (4.4+) or iOS (8.1+) phone to the watch.
