The 10 Day Tourbillon ref. 5101P is another grande complication from Patek that embodies this mastery of haute horlogerie. The finishing is of course spectacular, like the octopus wheel which has wonderful details in its finishing that need to be seen up close. Specifically, it’s the four sharp points at the end of the black polished tourbillon bridge that prove why this is one of the most magnificent tourbillon watches today. Patek Philippe was also a first mover with this watch which was unveiled in 2003. Not only is it a tourbillon but it also has a 10 day power reserve. The long and sleek case is distinctively Art Deco, with its stepped sides.
