Using some of the cool features in Excel 2010 (like spark lines) I built a fun chronometer accuracy tracker. A chronometer is a living breathing machine. You can use the spread sheet to help you track your behavior to better understand your relationship with your time piece.
Even a quartz watch will be more accurate than the finest mechanical chronometer. See what Prestige Time Website has to say about chronometer accuracy:
In the world of mechanics, anything assembled of small parts which are capable of maintaining 99% accuracy would be considered a top-tiered piece of machinery. To put things in perspective, if a watch is only 99.9% accurate it would be off by 1 minute and 27 seconds per day – which is unacceptable in the luxury watch world.
Here is a screen shot of the spreadsheet :
