So yes, the one year to make a Rolex is BS so is the “Hand made” term used on high horology.
While very part is supplied by robots, the assembly is still done by watchmakers at Rolex.
The videos we see, e.g. AP, Lange, Patek, Kari, depicting a watchmaker assembling a high complication piece, it’s also a sells pitch, since every one of them has a “quota” that they have to meet otherwise out the door they go!
So yes, the Zeitwerk minute repeater might take longer to assemble then a Datejust, but definitely not years, If someone believes that it does, then Santa is real;-)))
