One of the major noteworthy improvements on the system is the split seconds chronograph system. The old ‘octopus wheel’ isolator system used for handling the split seconds hand is changed to a much for efficient ‘swan neck’ isolator system. The big advantage in this is the ability of the thinner swan neck to rotate rapidly in both directions over the unidirectional nature of octopus that requires bigger isolator wheel spring for its effective operation. The end result of this change is the split system that is much more reliable, durable and user friendly.

Another noteworthy feature associated with the 5204p is the mechanism created to reduce the offset between the chronograph hands. As the chronograph hand movements are related to each other, there are some chances of difference arising among them. Most watch creators try to hide this and this was the practice followed even in 5004. In 5204p, Patek Philippe got the precision right on the money. They perfected the complex geometry of their cam and roller system by ensuring consistent contact among the moving parts of the chronograph.

Patek Philippe can be proud of this new timepiece added to their stable. Even when they stick to the perpetual calendar split-second chronograph DNA associated with the Patek brand, they are making full use of the latest watch making technology available in the market to convert the newer version in to a much more powerful and aesthetically pleasing gadget. With the level of sophistication that goes in to the watch, it is a piece of art that is certain to stay close to your heart. Whatever you look at, be it the 40mm case, the stylish dial, readability or finesses, the 5204p is definite winner.

5204p-001 costs $317,500. You can learn more about it at Patek Philippe’s website.
