Rolex Yacht-Master II
Introduced in 2013, reference 116680’s movement is in fact the result of
a titanic R&D process which took about 35’000 man-hours, resulting
in a truly innovative regatta countdown timer. While countdown timers
have been made before, never in history such a complication included a
programmable mechanical memory which allows to choose how many minutes
(1 to 10) the countdown lasts, and retains the information after reset.
