Like one of the other reviewers of this watch the glass on my watch cracked within a few weeks of purchase. I also did not think I had knocked it.... perhaps there is a flaw. Six months after having it repaired the crown fell off and the strap fastening had broken. It is now away for repair yet again, twice in nine months. My watch is a slightly different model, black with crystals set round the face, which cost just over £100. It is a great design but I couldn't recommend it as I would expect a watch of this quality to last longer.
