Rolex DateJust Accuracy since October 1st, 2009.

9/11/2009

When visiting Singapore a couple months back I took my DateJust in for a regulation. Since then I have kept to the practice of setting my watch on the first of any month that has 31 days, and this allows me to ‘run’ the watch till the next setting 61 days later.

As such my DateJust was last set on the 1st of October 2009, making it 40 days till today. I was randomly taking a look at the wwp.greenwichmeantime.com site and realised that my watch had only gained a total of 2.5 seconds till today!

This is quite incredible as it means the watch has only been gaining 0.0625 seconds each day, on average. While I have not been keeping an eye on its daily variance, over a period of 40 days this is pretty fabulous.

My entire collection of Omega watches comprising of four brand new purchases, at the time, and another four near-vintage Speedmasters could never reach this level of accuracy. They did, at best, at most about +2 seconds per day.
