What this reference is documented to have carried, and in what capacity. A service part is the manufacturer's own work; only a counterfeit classification is a finding against the watch.

Specific to the 42mm case. A 3186 in a watch presented as a 216570 more likely means a misidentified reference than a counterfeit — the 40mm and 42mm Explorer II are easily confused in photographs.
