8 grand is a stretch for a steel sub, but an 16610 (roughly 10 years old) would easily fetch close to 5 in a pinch. A pretty new 116610 lightly used you could turn into $7000 cash without too much trouble.
Precious metal rolexes don't hold their value nearly the same way as steel ones, since part of owning a gold rolex is the accomplishment of being able to buy it in the first place. They also come with a dizzying array of options, so if you want the right one you have to buy new. Sports rolexes have few options so they are interchangeable. Rolex has pulled off a neat trick of making them thought to be rare while selling nearly a million a year.
