The no-brainer for me would be to assume a watch that's 10 years old likely needs a service and factor that into my overall purchase cost.

Except isn’t it usually the case that new watches that sat unsold in an AD’s display for years, (which used to be common) are still considered new? I don’t think the synthetic oils they use today are that quick to dry or deteriorate, especially with no use.

Rolex themselves seems to feel an unused watch is still a new watch regardless of age, which is why they switched to random serial numbers.
