The most significant feature of this potential product is the removable screen, which can be inserted in any other fitness equipment or into a standard bracelet which you will get by default. Functions such as measuring steps, speed or heart rate would thus be able to perform on the user's hand and on the other equipment like treadmill, bicycles etc.
Of course, this watch should be able to show the time and serve as an alarm clock, a music player and much more. Other hardware details are not known, nor the fact which OS Microsoft plans to install in this gadget.
