Unique And Special Design Of UK Patek Philippe Advanced Research Limited Edition Fake Watches

The Advanced Research Travel Time is an obvious departure from previous Advanced Research watches. It is, first of all, the first Advanced Research watch to not be an annual or perpetual calendar; it is the first not in a round case; and moreover it’s pretty resolutely non-traditional in styling. In addition, it’s the first Advanced Research watch to present an innovation in a material other than silicon. the Arabic numerals Patek Philippe Advanced Research Limited Edition replica watches are the best watches for men to wear.

The Ref. 5650G Aquanaut Travel Time Advanced Research

The first, and most obvious, innovation is the “compliant (flexible) mechanism in steel.” This is the mechanism for adjusting the GMT indication forwards and backwards.

You can see the “compliant mechanism” on the left, and it’s a pretty piece of work. It’s all in steel; there are no exotic materials used, and while Patek says it required considerable computer time, as well as high tech manufacturing methods (the press release isn’t specific but electric spark erosion is a reasonable candidate) it’s still, strictly speaking, traditional watchmaking with traditional materials. It is fun to think, given its appearance, that it might have been nicknamed “the Crab” at Patek.

The level of precision required probably could not be achieved with classical methods – the clearance between the leaf springs, where they form an “x,” is only 150 microns – but the whole thing is hand-finished (which must have been, given the configuration of the mechanism, and to put it colloquially, a royal pain in the ass for whomever had to do it) and it looks very cool as well. It has a kind of intuitive appeal; almost no one could imagine such a thing but the basic principle, and construction, seem obvious and self-evident when you see it working. The easiest way to understand how it works is to watch this little short from Patek Philippe.

The Crab (if I may coin a nickname) has a lot of advantages over the usual GMT switching mechanism used by Patek – lower parts count (12 parts for the whole assembly, as opposed to 37 in the standard mechanism) and, just as significantly, no gears or pivots. That means no need for conventional lubricants, no friction anywhere in the mechanism, and very probably, much better durability and general functionality. The only downside I can see to it, is that it doesn’t seem repairable; if there’s damage or wear, you’d have to swap out the entire mechanism for a new one – the shell would molt the Crab, instead of the other way ’round. It’s damned clever, anyway.

The other innovation is the addition of a new inner terminal curve, on the Spiromax balance spring. Let’s look at the old and new versions, side by side.

Spiromax Balance Spring, 2017 Edition

If you look very closely, you’ll see that the innermost coil of the new version has a slight swelling in the coil, similar to the one in the outermost terminal curve. Just as the geometry of the outermost coil duplicates many of the advantages of the Breguet overcoil, so the new geometry of the inner coil duplicates that of a balance spring with a properly formed inner terminal curve. The basic idea behind all this, is to set up the balance spring so that the center of gravity of the spring always coincides with the exact center of gravity of the balance – this is the basic precondition for isochronism. With the addition of the new inner terminal curve, Patek’s been able to get pretty fantastic rate stability out of the watch – as we mentioned up top, the spec is just -1/+2 seconds per day.

By the way, there is an analogous technique with traditional balance springs. Just as the outermost coil geometry of the Spiromax duplicates the effect of a Breguet/Phillips overcoil, so the inner geometry of the 2017 Spiromax duplicates the effect of a mathematically correct inner terminal curve in a steel or alloy balance spring. One such curve is known as a Lossier curve and it was widely used by the American watch company, Waltham, in its high grade railroad watches.

The Aquanaut Travel Time Ref. 5650G blue straps Patek Philippe Advanced Research copy watches sit right in the middle of some very strong and interesting debates – the role of silicon in watchmaking is a big one, and the jury is still very much out on whether it has a place in high end watchmaking, although in the entry to medium range, the issue is already settled. It’s well on the way to becoming ubiquitous, as least for many major brands (Omega is the most prominent example).

It’s also a watch that raises the question of how Patek Philippe sees itself evolving in the next decade. Style-wise, this is a polarizing watch; it doesn’t have the easy to like classic configurations of the earlier Advanced Research watches, which are a sort of Trojan horse for silicon. The open dial and the fact that it’s an Aquanaut have raised some hackles amongst the Patek faithful, which I understand (in general, I can’t stand open dials either). With the 5650G, though, I get the logic – this is something of a demonstration model, and it makes sense to make the mechanism visible.

Certainly, there’s quite a lot more fun in seeing it in action, than there would be in watching a silicon escapement do its thing. It’s worth bearing in mind as well that this is a limited edition specifically designed to showcase new tech, and as a limited run concept piece with that tech, the design makes sense even if it’s not to everyone’s taste.

It has to be said as well that these are both extremely interesting innovations and if nothing else, I think that in addition to being pretty cool on their own, they both offer real technical advantages (albeit there are tradeoffs in any engineering solution). Maybe most importantly, though, both add tremendously to the general conversation on modern mechanical horology, and where it’s going to go in years to come.
