"Special nature of the four-digit year indicator: the year is indicated via four positions.
The display of the year’s first two digits (the centu-ry) is fixed. It consists of a small two-position plate, screwed onto the movement, which can indicate “20” or “21”. The decade display consists of two discs which run through the positions from “00” to “99” according to the perpetual calendar mechanism. On 1 January 2100, the watch will therefore indicate the year 2000 (fixed “20” + “00”). We advise you to wait until 1 March 2100 before submitting your Master Ultra Thin Perpetual watch to an authorised watchmaker, so as to have the year plate set to position “21”, while the necessary adjustments are made to the date and the moon phase."
Reading that, I can't imagine a century FIXED indication! In my case, for sure it will be hardly a problem, as I recently turned fifty... but hey, to my eyes it seems at least a sad choice!
I really like the model you asked for... with its "only two digits", but really kept in motions by springs, wheels and levers!
Hope to see this beauty soon on your wrist!
Best,
