Congratulations on the new 5088P
and also the other exquisite and beautiful rare handcraft pieces you have. One will never get tired of looking at them and please keep them coming : )
Personally, I like all kinds of rare handcraft pieces as each of them represents a special position held by Patek on the market which makes the brand so unique and special.
No particular favorite but I would also like to mention the 5180 as one of the most special rare handcraft pieces imho. Patek basically revamped the entire 240 movement.
