Sorry to boast, but I just can't help it. My 27 year old Rolex Date-Just again today. I've worn it continually since I reconditioned it in mid-November 2016. As of this morning, it is 23 seconds fast since then. It would be +26, but it dropped three seconds when I adjusted to DST in mid March. Since that adjustment, it has varied less than 3 seconds. It has always been an excellent timekeeper, but it has excelled, lately.
I never was a great one for lollipops as a kid but something came back from our friends at STS today and I can't stop looking at this particular lollipop ... I almost want to lick it ....
