Just checking the Apple Store app, it seems a lot of the straps and models (particularly Stainless Steel) seem to be unavailable. All colours of the Classic Buckle (except Saddle Brown) are unavailable. Even a white sport band is not not in any store around London. Is this a sign of some kind of refresh? I wanted to buy a 38mm SS with Pearl Nylon as a gift for my sister, but it's 8-10 weeks to pickup or delivery. I was in a store yesterday and the sport band display was basically empty. Is it similar in the US? Wonder what's going on!
