Speedy Gonzales says, "If you have time between flights, throw some polish on your damn shoes...you have the technology!" Mission accomplished...good times!
Still my long term tester. My 28-year old Rolex Date-Just. I serviced it in November 2016. Re-set once since then, at the change to MDT. Maximum total variation since then? At one point, it was 27-seconds fast, but dropped back 3-seconds at the time change. This morning it is 15-seconds fast. Lost nine seconds since the time change. If it was yours, would you worry about this degree of time variation?
