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

Oh, definitely! Price is half the game here. It could be the best thing in the world, but if it's expensive, I'd be too preoccupied with keeping it safe.

My sister keeps asking why I keep using my backpack when it's literally falling apart at the seams, when I have a perfectly good one in the closet. This is exactly the reason. :)
