I wear watches that are between 50 and 130 years old on a daily basis, my "beater" is 54 year old Eterna Kon Tiki. I've never had any issues with wearing any of these old watches, they are meant to be worn, not just kept in a safe or a shoebox under the bed. I keep them serviced and only wear my Kon Tiki if I'm fishing, canoeing, swimming, or doing anything that could result in its immersion on water.
