I would like to know from those that have or had hand wind watches, was there ever an issue with water resistance if it was used and wound daily for a lengthy period. It only makes sense for the gasket to get a lot of ware and tare after years of HW. Basically how long were you able to go without replacing the seal. My concern is if it used around water often or just wanting to clean it by rinsing it under some water you might not know until it is too late. Are they built to last longer then say a auto in regards to the seals and say the whole movement itself.
