> What's the chance of somebody losing their phone and their watch at the same time?

This question is loaded with the assumption that somebody has to lose them. No, it's enough for them to place them unsupervised in the same place, at the same time, regardless of how that's done. Examples:

* Four dudes rob you in a shady alley * Someone breaks into your home while you're sleeping * Someone goes through your things while you're changing at the gym, or even at the doctor's. * Someone grabs your phone while you're sleeping in a train * Someone steals your phone and spoofs the Pebble

The "what's the chance" route is ok for small-scale, low-sensibility deployment. If there's one chance in a million per year and there are 5,000 units deployed, 99% of which contain nothing but boring contacts lists, it's a reasonable route. Not ok from an engineering perspective, but ok from the point of view of a company that sells consumer devices, for whom product quality is nice to have, but not important.
