5235/50R; Patek Philippe’s Annual Calendar That Dares To Be Different

One can wonder if Patek Philippe would have known that when they launched their very first annual calendar in 1996 that it would have become such a popular complication. Today, its popularity even goes beyond Patek Philippe itself, as many other brands have developed watches that feature this complication. For Patek Philippe, it has become one of their signature complications, and many of the watches fitted with it, follow the classic dial design for calendar watches. There is however one exception, and that is reference 5235/50R.
