Derek, I read the section about accuracy that you wrote in your helpful Seamaster Owners' Guide on this website. I am trying to do the experiment you suggest, but am unclear as to whether I should be constantly resetting my watch every day. I read today that doing so causes wear and tear on the gaskets.

In particular, you write:

"Before you go to bed, check the accuracy of your watch against a reliable time source. Write the information down, then place your watch on the nightstand and go to sleep. When you wake up, measure the accuracy again, write it down, and put the watch on. For the next several days, keep doing the same thing except put the watch in a different position each night. Try face up, face down, crown up, crown down, 12 o'clock high, and 6 o'clock high.

After you have tried all the positions, you will have a list showing exactly how much your watch gets off during the day AND how much it gains or loses in each possible position at night. Find the position to keep it at night that does the most to cancel out the variation the watch experiences during the day.

For example: If your watch loses 5 seconds while being worn during the day, try to find a position in which the watch gains about 5 seconds overnight. That way, by simply knowing which position to put your watch in on the nightstand while you sleep -- you may be able to cancel out the daily variations and have a very accurate watch!"

As you can see from my results below, I am achieving varied results, and have only been running this experiment since Sunday. However, you can also see that I have been adjusting the watch to the Atomic Clock website (the URL I have been using is http://www.fridaystoast.com/clock/index.html). Is this unwise, or does it matter? Thanks. Here are the results so far:

WEEK ONE Sunday, December 12, 1999 1:17 a.m. adjusted to Atomic Clock in box for the night, face up

Sunday, December 12, 1999 9:36 a.m. running 1 second fast no adjustment out of box for the morning

Monday, December 13, 1999 1:46 a.m. running 4 seconds fast adjusted to Atomic Clock in box for the night, face down

Monday, December 13, 1999 10:24 a.m. running 3 seconds fast no adjustment out of box for the morning

Monday, December 13, 1999 11:05 p.m. running 3 seconds fast adjusted to Atomic Clock in box for the night, 9:00 side down

Tuesday, December 14, 1999 8:15 a.m. running SPOT ON! no adjustment out of box for the morning
