The dial of the Diesel On DZT1015 Armbar Hybrid hides a lot of smart functions. When you connect the hybrid watch to your smartphone, the watch vibrates with incoming smartphone notifications. Don't want to be disturbed? Simply set which notifications you want or don't want to receive. You can also use the watch as a stopwatch or set an alarm. Do you keep track of how much you've moved? The Diesel On counts your steps, calories burned, stairs climbed, and records your sleep pattern. The watch is waterproof to 10ATM, so you can also swim and dive.
