My husband bought this watch -- he has been a Skagen watch wearer for many years and his most recent one began stopping and then restarting every so often (battery was not the issue).  It was old, warranty info was long gone, so he bought this one.  He read the reviews about cracking crystals, but decided to go with this anyway.  Well, he has had it just over one month and the crystal developed a crack which was small at first and then grew.  He had a watch/jeweler put on a new crystal, so its like new again, but the jeweler said that since the crystal is thin and exposed (the edges of the crystal are slightly above the metal casing), that he might be back for another replacement crystal.  Switching to a sapphire crystal wouldn't help according to him -- both mineral and sapphire are hard and are easier to crack than softer plastic crystals.
The older Skagen was a different design, without the crystal edge exposure -- no problems with that one.  If the new one didn't have the crystal issue, this would be a 5 star.  Incredibly comfortable.  Easily and fully adjustable band (nice to expand it just a bit for summer).  The band catch is great (some reviewers complained about this -- no idea why!).  And very classy looking.
He'll see how things with the new crystal, hoping for the best....
