Which is often the case... Any quartz watch is similarly or more precise than the most expensive mechanical ones. Any "radio controlled" watch (increasingly popular at least here in Germany) has no time deviation at all. But accuracy is not the reason people buy expensive mechanical watches. Fascination, status, etc... To some extent the same happens in the audio "circus". With 40-50 years of age, many can at last afford "their dream setup" - what they can't buy is the hearing they had 20-30 years earlier, so they compensate it with glamour and such. Life is hard and then we die...
