between the choices of the two, 5959 in a heart beat.
5078 indeed a pretty watch, but there are models higher.
But 5959 is in a league of its own, hard to compare ...
I took this picture when I visited auction. I really like PP Logo at the back.


While I would love to have a 5078, the 5959 is unique and one of the rarest watches in the world.
Simple, elegant, yet very complex and difficult to build with only a maximum of 10 made per year. Amazing engineering to make a split of this type in a movement so small. Truly extraordinary and destined to be a Patek classic.
The difficulty is not in choosing the 5959 over the 5078 but trying to decide between the white and black dials of the 5959.
