I wear mine (silver and gold) 24/7 including to the shower and gym, they only get better. I don't spray perfume directly on metal though and don't use lotion/hand sanitizer etc to go in contact with them - chemicals may tarnish it.
@TatkaS, I am the same as @GemsBerry, I wear my silver one 24/7 (work, gym, run, shower, etc.). I do use lotion/hand sanitizer/cologne/etc. and have not had any issues. I might once a year get it cleaned at the store if I remember.
