Is that all Diesel could deliver?


Frankly I'm very disappointed in Diesel. I never though such a prestigious brand will get into making something without putting its 101% . Don't get me wrong the design is nothing less than what is expected (I have the sleep monitor in brown-black), but the functionality of it is an absolute joke. There are many knock off Chinese wellness trackers which do more for much much much cheaper price. The calorimeter is very inaccurate the sleep tracker is not right either. The interface is so useless that I have found myself staring into the different parts of the app screen just in hopes I find something new to click in case there are some functionality that I might have not discovered. I feel I have placed too much trust in my beloved brand.

Good smartwatch, app though not so great.


I have a Diesel hybrid smartwatch (black/gold model). The phone is responding to the watch button inputs and sending notifications so I can tell the watch is connected and functioning but the app doesn’t want to recognize that the watch is connected at all. I have to restart the app multiple times (sometimes over 20 times + refreshing in-app) until it finally detects that the watch is connected. It’s frustrating because I love this watch and I’d love to recommend it to people but the app on iOS just isn’t up to par.

It’s ok watch


The watch style is like expected for Diesel brand Strong and Industrial. Unfortunately the the technology is wasn’t there yet. Some issues with the vibration of the watch and battery life it wasn’t that great. Looking like you need to spend more money to buy the batter. Maybe it will be better if it have rechargeable lithium battery.
