Battery low issue

Love the watch but I can't get the replace battery to dismiss. I replaced as per instruction. Tried sync, rebooting app and everything I found online. Watch works fine but always read low battery. Please advise.

Some good things and some bad things

Personally I really love the diesel smart watch I just got. I love the features you can customize it with on the app. Having school I like being able to change the side buttons to the date and what ever instead of it controlling the music. I really like this feature because my music won’t go off in class. But there are some suggestions I would like to make I wish that in the app it would tell you how much battery your watch has so it does not die on you. Also I would like to suggest in the app having more goal tracking expansion because I would like to add other goals but sadly I can’t add some of them but over all a very nice watch and a nice app

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.
