I didn’t know this model until I sat together with a dealer, whom I tried to persuade to sell me his Patek 5107P. He told me about this perpetual calendar, which was still being serviced. Yesterday I was able to see it live for the first time and was immediately impressed.
The case is the perfect size for me, not too big and not too small. The PT creates a pronounced heft on the wrist without being uncomfortable.
All in all this this AP is a great piece with a lot of bang for the buck. Compared to every Patek with such complication and material it is much easier to obtain.
And as a big lover of Breguet numerals I had to pull the trigger anyway 😄
