Keeping time

So I have been a Rolex guy for the 25 years, various models, but have never actually tracked their time keeping. So on 7-10 I started to keep a running log of my newest addition, an Exploer II. As of today, 13 days later it's running DEAD on at +/- 0. Over the course of the last two weeks, I have been wearing it everyday, and placing it in different positions on my night stand while I sleep; documenting the gain/loss each night before bed, and each morning when I wake up.

Some observations, it seems to gain time, approximately 1-2 seconds laying crown down. It loses 2-3 seconds laying crown up, and laying flat seems to be around 1-2 seconds of loss. With that said, the most it has been off has been off has been -4 on one day, with averages on -1 to -2 a day, and a day or two where it was +2. For the last 3 days it's been right at -/+ 0. I have been using Time.gov as a baseline.

Pretty good I think.

I agree that is pretty good, thanks for sharing! I find that in an approx 28-30 day period my Sub "performs" best parked crown up as does my wife's DJ, my DJ is best parked 12 up. All three gain less than 2 sec. per day.

You can't ask for better accuracy than that.
