Small size 1.3 + large size 1.7 = 3
Half Life 3 confirmed on iWatch.
I wonder what kind of charging options they will choose. Lightning would be unsightly on such a small device on your wrist. It would be a first if they add Qi/inductive charging. I hope there will be an elegant way to have it charging while docked on your nightstand!
If apple was smart, they could try what Citizen does with their watches, SOLOR cells in face. However, I am not sure how that will work with the OLED, so that might not be possible. Also, I know another watch brand that uses MOTION to charge the batteries, forgot who made those. But your right, a charging port would be really BAD on these watches.
