I examined these at my local UK Apple Store last week. The stainless steel "block" is the same size as a 42mm watch. It is a solid block - no crown or buttons. They look very smart in store. I guess it's a cheap and very effective way to show off the straps.Brilliant attention to detail! I don't think these are at my local store [Robina, QLD] due to limited space inside the store. But yeah, they do just look like a solid block of stainless steel. They don't have a Digital Crown either by the looks of it right?
Would be awesome if someone could get a closer shot!
