This is my 3rd (or 4th?) Apple Watch - I've tried out every generation Apple since the first version Apple released. I opted for the cellular version and set up that feature for a few months. It works great but I don't have a regular need for making/taking phone calls on my watch without my iPhone nearby.
This iteration of the watch is the 42mm, Space Grey. I choose the 42mm over the 38mm after my first watch. I really appreciate the increased screen size.
