Random observation regarding 5712

[debner4]

I saw some macro photos of a 5712 posted earlier today, including of the movement, and the movement stated that it was "adjusted to five (5) positions" which is what I generally recall being the case with Patek and the 5712. But when I looked at my 5712 just now, which was purchased in 2017, it says "adjusted to six (6) positions."

Does anyone know when Patek changed from adjusting in 5 positions to adjusting in 6? And does this apply across their movements, or just the 240 and/or 5712?


Just curious.
