Heh...Clunk's post is the best...is that my little pony? Gosh scary I know that...!
Yes, a $20 Quartz watch will out perform any mechanical watch, but say it's calibrated to +2secs, in a couple months time, it'll STILL keep that +2secs.
However a mechanical watch will vary depending on temp and gravity, i.e. here's the COSC cert. I got for my Seamaster,
So even if it is off today, in a couple months, i could deviate ± around that point, which could be good/or bad.
However, to be purely functional, a CPB (cheap black plastic) can not be beat.
OTOH it seem that the general census here is "why drive 'nice' cars, enjoy fine liquors when the regular 4 wheel kind or the 'unbranded' whiskey gets the job done". Again, it is all down to a matter of taste I guess, and some people find pleasure in these 'eccentric' ways of life.
"why you're so infatuated with them"...
Until October '06 I only owned two watches, both Tissots which were gifts to me from my Parents, even though I've always been fascinated with watch movements and the 'engineering' that goes into creating these mechanical marvels.
Since then the collection has grown and I'm favouring the pieces by Omega specially the Sea/Speedmasters. Looking at pictures etc will not mean anything, until you hold one in the palm of your hand - if you are still convinced that 'they suck', to each his own ofc.
...chances are you'll leave the store thinking it over.
