To take care of it for the future so that it's value is not diminished. Even a small scratch on a rare watch will drastically cut its resale value except in exceptional circumstances.Retire from daily duties? If you're not going to wear it, what is the point?
it's always the people who say silly things like, "duuude, get that Aston Martin db5 out of a museum and drive It like it's meant to be driven" who have little appreciation for taking care of things of value.
If this was some other mass produced watch, then sure.
