I’m have great difficulty here in the UK sourcing extra long watch bands for my series 4 watch. Unfortunately I’m blessed with rather large wrists (9 ½”), along with other oversize body parts (no, not that, and don’t laugh). I really like the look of the Sport bands, but have never found one long enough, but I suppose any style will do. I’m getting fed up with standard leather straps that I’ve made fit with aftermarket strap adaptors. Does anyone, either here in the UK, or indeed anywhere, know where I could find a decent selection of what I’m after?.
