Wristwatch, version 2, as desirable tech

It seems like no one less than 30 years of age wears a wristwatch any more. Why? Because they carry smartphones. In the near future, however, lots of under-30s are going to be wearing wristwatches. Why? Because they carry smartphones. Prepare for the imminent coming of the smartwatch, the new partner of the smartphone. But why did people stop wearing wristwatches? Because almost every cellphone ever made, from the first \"candy bar\" phones through flip phones, feature phones and finally smartphones, could do what a watch did -- tell you the time. People soon came to note the redundancy of it all. Why a watch and a phone both? And given that a phone could tell you the time but then do so much more, why a watch at all? The phone got its time from the wireless network it was on, so it was always accurate. Oh, and no more having to set the date after your watch, with its built-in 31-day date cycle, got it wrong following a 30-day month. So watches went into the dresser drawer. Need to know the time? A quick look at your phone and you had it.
