I was a commercial diver and diving instructor for 30+ years and bought such a Rolex in 1965. I wore it everywhere never taking it off (not even for sex). Funny thing is it NEVER kept time no matter how many tune-ups, cleaning etc. it got. I always thought it was the rough life and figured any other watch would have just died.
The bezel was even pitted with rust and the stem winder was broken when I sold it 3 years ago for $3500. The cost to repair would have exceeded its value and I am too old to wait for any appreciation in value.
My kids were pissed because they wanted an heirloom.
