not my watch, just saying everyone claiming it is the pebble steel band, it isn't. It's an inherent design flaw with the watch. I have had the pebble steel band on my watch almost three weeks now, no cracks.
There's an idea floating around now that the issue may be made worse depending on the size of the wearer's wrist. With a smaller wrist, the band would put more pressure on the backplate. But with a wider wrist, the band will go out straighter, meaning less contact with the backplate.
Something else to note, we have no way of knowing if this is truly a defect, or if the guy had a derp moment and is hoping he can get it fixed under warranty. Unless you start seeing significant numbers of this occurrence, like 25%, I wouldn't necessarily call it a defect. From what I've seen so far, I don't think we're there yet. But I'm not saying it's not a defect either, just with what we know so far it's a little early to say that definitively.
