I don´t know what kind of job you have but unless you operate a jackhammer, your Rolex should be alright! We´ve seen swine breeders and rodeo champions with Rolexes on their wrists and they were fine

Oh, a Rolex perpetual winds bidirectional. If you can set the winder CW or CCW only it doesn´t matter which way you do it - they both work just as well.
