Thank you Al, for this very interesting and educational article.
I have a Credor quartz as my work watch for the last 10 months, adjusted the time twice a year for daylight savings plus a couple more times due to travelling across time zones, and it has never been off more than 1 second. According to the manual, "in order to set the time accurately, turn the minute hand 4 to 5 minutes ahead and then return it to the correct time". I am just curious, what would be the reason(s) for that instructions?
