I'm not saying the watch isn't engineered with precision as clearly it is, but one knows something is wrong when Rolex guards its manufacturing processes the way of state secrets (no one outside the company can gain access to its plant). Of course, Rolex claims this is to protect it from industrial espionage, I'd equally argue that its highly automated precision numerical control equipment can turn watches out like sausages and the company's ongoing worry is that the world will discover how cheap they are to make. That would be a marketing and PR stuff-up par excellence.
I would not buy a Rolex because I know I'd been ripped off. BTW, my grandfather was a watchmaker and jeweler and he taught me to be aware that much of the trade was build on illusion and mirrors. He didn't just repair watches, he had a precision watchmaker's lathe and similar equipment and could make parts, gears, subsections of Incabloc shock protection systems, etc. for watches and clocks that weren't available in suppliers' spares catalogs. He not only repaired jewellery but also made it. I have a gold and platinum tie pin with a black opal made by him (mind you, I wouldn't be seen dead wearing it).
Right, not only have the rich and powerful always valued diamonds but also most who've come in contact with them and other precious stones have always done so. But it was only in the 20th Century, and then mainly in anglophone countries, that diamond ownership took off among us commoners as a result of cleaver marketing.
