i originally had the Classic Buckle that came with the Watch but swapped for a Leather Loop (black, medium) and there's just one thing bothering me about it: the straps will flow over each other as you flex your wrist and it causes weak vibrations like the taptic ones. Sometimes they're stronger. Yes, the 'vibrations' or rubbing are on the wrong side of the wrist and much less focussed. The false-positives come when you're distracted. Anyone have the same experience?
