But in this family, I actually like the unsung, less popular Referenzuhr.
There were lots of debate on the Referenzuhr here in 2010 when it was released but at that time, most people aren’t used to off-centered sub-dials….fast forward today, look at FPJ and many watches where the seconds sundial is placed all over the place.
I also think the Referenzuhr was overshadowed by the 165th Anniversary pieces but the movement architecture is special and beautiful than PLM, aesthetically.
