Thanks for posting. I think the guy is right, technically speaking. But watches are emotion. Otherwise people wouldn't spend a lot of money on mechanical watches, while they can buy a more accurate quartz watch for a fraction of the price of a mechanical one. And: don't we all want a unique piece? Or a movement that's rather unique, or a limited edition dial (see for instance the prices that ar payed for the Tangente super 30 series), or a combination. For many watch collectors (or addicts) reliability seems not their main (or only) interest in a watch.
