A 'half or even full hunter" is far more durable than a smartphone. The metal case protects the delicate insides. The round nature of the device makes it slip in and out of pockets with ease as opposed to most smart phone (even those with rounded corners).
The chain properly attaching it to ones clothing makes for a perfect device. does the job it was intended to do perfectly and no silly wrist band.
As I said, I hate things on my wrists. So the likelyhood of me stumping up for a watch if this type is as likely as Leicester winning the Champions League.
now where the number of my bookie?
