even at 4 seconds a day off, it's 99.9953703704% accurate per day. i think this thread is perfect because someone a few posts ago said that people bet their companies on specs, and yes, a grand seiko tuned to 10 seconds a year is much more accurate than his rolex, but at essentially 1000ths of a precision digit they're 100% accurate. do you think your car's speedometer is that accurate? or can you differentiate something at 0.00X dB level?
Just saying your Rolex is "very accurate" does not "goes to show" anything at all. Especially considering that your Rolex is in reality horrendously inaccurate! Most probably your Rolex is accurate to within about 4 secs a day, possibly about 2 secs a day if it's just been serviced. Your Rolex is about a hundred times less accurate than a high accuracy quartz watch and about a hundred trillion times less accurate than the most accurate clock! All of which goes to show that generalisations absolutely CAN be made about the accuracy of mechanical watches!!
