Saying a new Patek Philippe¬†5204r prix replica watch reference is impressive is sort of redundant in itself. But the 5204 is really impressive. It’s a new perpetual calendar with split-seconds chronograph for Patek, replacing the 5004 in the lineup, and offering a number of major improvements. We have our hands on a single back in Basel 2012 and have the particulars.

We are going to start with the simplest differences. First, Patek has chosen to up the situation size from 36.7 to an even 40 millimeters in keeping with the modern trend for larger watches. It’s a huge jump, but 40mm remains a more than reasonable dimensions and looks quite good .

But it’s what’s under the hood that really makes the difference here (and it’s nearly a $75,000 difference, by the way). The 5204 is powered by means of a caliber CHR 29-535 PS Q movement, with a Gyromax balance beating at 28,800 bph (4Hz), which can be a substantial change from the 18,000 bph of this 5004’s CHR 27-70 Q. Beyond conquer rate, however, the 27-70 Q chronograph was established on Lemania’s excellent movement, and then heavily modified in house at Patek, while the 29-535 PS Q is a true built from the ground-up, highly complex, in-house motion. It’s manually wound, has a 65 hour power reserve, may be seen via the sapphire case back (strong platinum is included too ), and is the eighth fully in-house chronograph movement from Patek Philippe¬†5204/1r-001 replica watches.

This in-house motion comprises a number of innovations, particularly for the split seconds chronograph system. The first is the switch from an”octopus wheel” isolator system to a new”swan-neck” isolator method for controlling the split seconds hand. The octopus could only turn unidirectionally and required a milder isolator wheel spring, whereas the swan-neck is very thin and can proceed quickly in both directions. The result is a far more reliable split system that is also more durable and easier to service when needed.

The next innovation is a mechanism for reducing the counter between both chronograph hands. Because the split seconds hand’s movement is associated with the main chronograph hand’s motion, there may sometimes be a slight gap between the two. As opposed to cover this up using a slightly wider chronograph hand (which most do, and also the 5004 did), Patek have mastered their cam and roller system to be dead precise. The geometry is relatively complicated, but the idea simple – more frequently predictable contact between moving parts and you get more precise interactions.

Overall, the 5204 is an astounding new addition to the Patek Philippe 5204r split-seconds chronograph perpetual calendar fake watches lineup. It maintains the iconic Patek perpetual calendar split-second chronograph DNA whilst utilizing cutting edge watchmaking techniques to produce the new iteration more technically impressive than the past. For a highly complex opinion in a 40mm case, the dial is clean, easy to see, and just flat out beautiful. This is a winner for sure.
