I don’t know about that. I have been wearing the same semi expensive watch daily for over 10 years and there is not even a scratch on the face despite having bumped and knocked it countless times. Worth mentioning that a watch repairer can replace most parts to get it looking good as new relatively easily if it came down to it.

Sunglasses on the other hand, I also go cheap - but that’s because it is much easier to lose them then something attached to your wrist! Haha
