Early today I wrote about a fascinating interview penned by my friend John Reardon with Dr. Peter Friess, curator of the Patek Philippe Museum. There is really so much in that story, I can’t recommend it enough. But what might actually be the most illuminating thing that we touched on for a moment in our story is that Patek Philippe acquired what very well could be the first perpetual calendar timepiece ever recently. That alone is worthy of a mention, but in our edit process (yes, every story you see on HODINKEE is reviewed by our whole senior editorial team to see how we can improve upon it) was something even more incredible – Jack found where and when this Thomas Mudge perpetual calendar sold for and for how much, and that is what I think bears repeating here.
