I am very pleased with the clock. I often carry a variety of conditions. I was so in the sea, had them unfortunately fall a couple of times already and am also triggered several times. No scratches or flaking. Even the glass is very hard and scratch resistant. As I said, the clock has already taken part in everyday use much, even when traveling, but still looks like new. Because I do not ever wear, I need it back and tighten again, but then the accuracy is very good. I would always buy me again, especially since it looks really good!
