Query: buyer BEWARE

I received this handsome watch as a gift for my birthday. Unfortunately, as seems to have been the case for others before me, my enjoyment was short lived.One night as I was getting ready for bed I took it off and put it on my dresser. About 10 minutes later, I heard a loud pop that sounded like a light bulb burning out. I got out of bed and went over to see what had happened, and was shocked to see that a large round disc had spontaneously blown out of the center of the crystal. I contacted Skagen, and while they initially denied that there was a problem with a faulty design, they quickly agreed to exchange it for a different model.I only hope that the problem with the crystal is limited to this particular model, and not to all Skagen watches.I don't think that Amazon should be selling this particular watch, and plan to contact them about this directly.
