On the Apple website it shows 34 variants of the watch in total across the three sections (Watch, Sport, Edition). Do we think you will have to choose one of these set variants or will it be completely custom on order? e.g. In the Watch section there is a Space Black stainless steel case - but this is only shown as being with the matching stainless steel bracelet. Will we be able to order this body with a different bracelet - or would we need to order a second bracelet???? All these questions!!!!
