Sorry, your definition is lacking a bit.

A "secondary market" and/or "replacement part" can be genuine (thus, not necessarily "aftermarket").
For example: You could have purchased a genuine, used, Rolex GMT dial and installed it in the watch (instead of that counterfeit junk).
In that instance, it would be a "replacement part" purchased on the "secondary market" but not "aftermarket".
In which case you would disclose it as a genuine dial, but not original.

The term "aftermarket" typically refers to part that works/fits with a specific manufacturer's product (either as a direct replacement, or as an "enhancement"), but not produced by that manufacturer.
A legitimate "aftermarket" part will not bear any unauthorized trademarked branding/logos of the company that produces the product in which it is designed to fit. In most cases, a true aftermarket part will bear it's OWN company branding/logo.
For example, companies like RubberB and Everest produce legitimate "aftermarket" straps for Rolex watches, which have their own respective logos printed on the inside (and NO Rolex logos/insignia).

So, as stated previously, if any part bears a Rolex trademarked logo/phrase/model name, and it was not produced or authorized/licensed by Rolex, then it is counterfeit. Full stop. Not "aftermarket" or "homage" or any other creative descriptors.
