I think it would have better to sell ALL watches with a black rubber strap and offer the other bands as options. That seems more apple to me and would make logistics a LOT easier.
All watch bodies should have come with a white or black strap everything else is optional. Simple maths
..You think they didn't have those bands ready? Of course they did...
In fact they all should be shipped with an ugly green so that people really need to upgrade.
Yup, the watch and the band should have each been sold as separate items in the first place, just like phones and cases are. Who cares if somone wants to put a gold band on a sport watch? Just price the two accordingly and get these things shipping.
