On the one hand you have all mobile activities in view of having to pick up the cell phone from his pocket without (new messages, email, Whattsapp, etc.), on the other hand, the Gear ready fit with supportive features for fitness on.
The Design of Gear fit is designed so that the Gear fit similar to a bracelet. The simultaneous wearing a watch is thus not a problem.
What I personally find a shame is that I can take fit no talks contrary to the Gear. I myself have the Gear 2 Neo - with this I can make calls without having to pick up the cell phone from his pocket. Therefore 4 stars.
