Coros men's watches with sapphire crystal

In general, it can be said that the best glass on a watch is sapphire. Sapphire glass cannot be scratched (only with diamond or corundum) and with normal use it remains as new for decades and the dial is 100% legible through it. The weakness of sapphire glass is its resistance to breakage. It can shatter if subjected to a strong impact. In our experience, we have not seen many broken sapphire glasses, but it is possible. We definitely recommend watches with sapphire glass!
