Query: Beautiful, but poorly manufactured

Great looking, thin and lightweight watch. Unfortunately, the crystal spontaneously cracked after a little more than 6 months. Apparently, that is a common problem with this watch and this brand lately. Luckily, Amazon was able to refund my purchase. My previous Skagen Titanium watch lasted 5-6 years, so I am unsure if I will purchase another one.
