If you look at all the videos and photos you can see the digital crown color in the centre matches each and every belt. How would you think that would work?
...Basically the band you bought is the one you're stuck with, just like a normal watch
Watch designed band (3ed party also) will fit and is user changeable to any
Watch as long as it's 38mm or 42mm. Basically the band you bought is the one you're stuck with, just like a normal watch
Watch and buying a sports band for when i'm exercising and buying other bands such as the Midnight Blue and a Stainless Steel Link Bracelet to change around for different occasions/moods.I know this isn't the case, but I would expect Apple to be smart enough and not color the crown at all. It would be so much more straight forward if the top of the crown would be the same material and color as the watch body.
The digital crown is only changing colour on the gold models, You can change the band if you want but there are limited options. Basically the band you bought is the one you're stuck with, just like a normal watch
