I am looking at maybe getting an Apple Watch. I've got my eye on on the 38mm model with the silver link bracelet priced at £819 http://www.apple.com/uk/shop/buy-wa...e-link-bracelet?product=MJ3E2B/A&step=detail# However i've noticed the silver link bracelet is available on its own for priced at £379. This combined with buying the Apple Watch with sports bracelet at £299 makes a total of £678, significantly less than the £819 for the getting the silver bracelet with the watch. I'm guessing I am missing or not understanding something here, as far as I'm aware the straps are all interchangeable? Is the actual watch different/not as good if I buy the sport edition?
