I'm not attempting to write a treatise on watch lexicon here (there are enough of those articles already). But to get a lay of the land fake rolex for sales, we'll need to look at many different calibers, some of which you might not consider eligible.

But let's start gently enough with a caliber we can all agree has some real horsepower.
