It depends on the watch. Some, perhaps, should be museum pieces. Otherwise, if it is a watch I'm going to wear, I prefer it in as tip-top condition as is possible. One man's dial with patina is another man's tired look watch. The look I like most, is of something pretty used, but well maintained. So, old and lots of wabi doesn't do it for me, nor does indestructible and unchanging.
Best wishes,
Bob
