Trying to learn how to spot a fake.

[Flaxmoore]

Mods, please move this if it's in the wrong subforum.

With that disclaimer out of the way, is there a good tutorial somewhere on how to spot fake Rolexes? I've a longish history collecting vintage pocketknives and have become quite good at spotting fakes there, but the watch world is new to me.

For example, using a replica site I found through a quick Google search...

I think I see a few differences between the replica on the left and the purported real one on the right.

What I see:
1. Second image- the Rolex crown on the crown (I think that's the term- what you pull out to set the time) looks muddy on the phony one. On the other, it looks much crisper.

2. Third image- the Sea-Dweller and other text on the dial appears engraved on the real one, while the replica looks painted and a touch blurred.

3. Fourth image- similar to the last set, except in this view it's the Rolex crown and "Perpetual Date" that look fairly muddled.

How did I do? Good start or hopeless ?
