Especially when you're talking about something like a watch, especially one that has been owned and worn for a while (like mine), plated would look pretty bad compared to solid.
In the same way that a trained eye may tell by just looking the composition of the gold, for example 14K, 18K, and what sort of alloys might be in there, or the difference between platinum and 18K white gold, so the trained eye may detect plated, especially on something like a watch.
Yes, to be certain you'd test, but doesn't mean that visually those bogus gold tone fake watches wouldn't give themselves right away.
