[time-nuts] Am I the only Time Nut who doesn't wear a watch?

[Paul Nelson]

There's a good writeup on accuracy on wikipedia-
http://en.wikipedia.org/wiki/COSC

includes a handy table comparing mechanical movement and quartz movement 
requirements.
To be considered a chronometer, the daily rate must be within -4 to +6 
secs/day. The stability of the rate over time is more important than the 
actual rate.

(Interestingly- any quartz watch or clock I have is much more accurate 
than my Hamilton Model 21 ship's chronometer!- a video of one of these 
beauties-
