Whoever reads through the description more accurate, should at "Glass: plastic" stop and think about whether he really wants to spend 150 euros for such a watch glass. I call this clock or the price an impertinence. Although it is Dugena, the company was formerly known for really high-quality watches, one seems to buy only the name but not the material or a good clock. Even the build quality can not change this, if at the slightest contact of the glass or the like with a metal a scratch in it. There at the price better with hardened mineral crystal and even sapphire. Absolutely no purchase recommendation!
