> With an armband you lose a hand for interaction.
Absolutely true.
What you gain is (some are more or less debatable and/or situational):
1) Stability. The device cannot be knocked out of your hands or dropped, unlike 5" phone. I can give you two situations where this is very safe where a phone isn't: in a store, and on a bike.
2) 24/7 on you, with the advantages you mentioned.
3) Less chance of the device getting grabbed out of your hands. If the device looks like a normal watch (and not like an Apple Watch) the chance of getting robbed for your watch stays approx the same.
4) Information leaking. Phone has this too. Phone has larger screen, watch with t-shirt is 24/7 seen.
