Greubel Forsey Nano Foudroyante EWT - Flying Tourbillon, Foudroyante and Chronograph
Thoughts on Greubel Forsey’s tenth Fundamental Invention
We know that Greubel Forsey’s replica watches for sale are extra-large and rather extrovert, along with at least one but often 2 or even four tourbillons, however their latest watch is actually modest in size and appearance. Yes… let’s think about it… The actual press release is mainly touting their own 10th Fundamental Invention, the actual special energy-saving foudroyante which saves nanojoules of energy. Individually, I have to say that the fast-spinning foudroyante hand is aesthetically annoying and distracting. Therefore to be honest, Greubel Forsey’s 10 Fundamental Invention was fulfilled with frustration at the start - in my inbox. But the mentioned case scale 37. 9 mm (from Greubel Forsey) made me especially curious to take a closer take a look at what it is.
So… Greubel Forsey’s situation is a lot smaller. That by itself is big news (pun intended). I was surprised this is their first wathe, a fact that was barely outlined in the press release! Moreover, it really is their first flying tourbillon. However , after seeing so many FRIEND watches with multiple tourbillons, you’re hardly tempted with a “simple” flying tourbillon. We are definately see more about that later on. But all the same, a watch chronograph from Greubel Forsey is already a real novelty using its modest dimensions, 37. 9mm in diameter and ten. 5mm thick. And since the rand name is not only known for adding lots of tourbillons to their watches, also, they are known for spectacular, first-rate motion finishing. So , all in all, this will be of interest to serious collectors having a very generous budget.
But let’s return to the story behind this appropriately named “10th Fundamental Invention”. A foudroyante is a hands that completes one complete rotation in one second to show fractions of a second. This particular complication is often incorporated in to chronographs to measure period intervals more accurately and/or much more clearly than a separate secs hand. But that is not the situation here, as the foudroyante palm is not connected to the chronograph as well as cannot be stopped. It is therefore ineffective in terms of reading the passed time very accurately. Franck Muller Vanguard Crazy Hours Vegas Racing
Here, the particular long hand is attached to the escapement (see further straight down in the article for more details) and, through its little long hand dial, gladly rotates in a circular movement above the flying tourbillon, whilst always remaining vertically focused.
If you enables me to digress a little, it is interesting to note that will early foudroyantes were made within Val de Travers about 1850 by Tixier (the great grandfather of self-employed watchmakers, now working with Dominique Renaud! ). These were additionally not connected to the chronograph functionality, but here they served as a simple seconds side. Its mechanism was " simply" a hand installed on its 4-tooth escape steering wheel which rotates once for each second at a frequency associated with 14. 400vph.
Coming back to modern times and Greubel Forsey, the work they have completed power the foudroyante may be worth a closer look, even though very little is mentioned in the pr release. The system seems to be derived from their particular Nano released in 2017 (patent EP 3220207 A1), that involves creating a display mechanism for any system that is driven by the first tooth and contains another tooth; an ultra-small equipment module, for driving typically the display directly or indirectly. The purpose would be to allow for a reduction in size, and for that reason inertia and energy usage. EWT stands for Excellence inside Wheel Technology, which requirements clarification.

For foudroyante, the idea is always to apply these “nano-mechanics” straight to the escape wheel (arbor), to beat 6 occasions per second. In this brand new 2024 Foudroyante, the screen is no longer lateral, so it is visible through a magnifying glass through an starting in the side of the case.
Instead, it utilizes a dedicated set of gears, often the differential, to display the “dial side” - which is a lot more practical. Another challenge with regard to GF was to create a element that was small and light sufficient to embed it within a flying tourbillon. One may wonder whether it makes sense to include such a component into a tourbillon designed to improve precision : which has always been a very severe topic for Greubel Forsey.
What impact would the added “burden” upon such a crucial part of the escapement have on the watch’s precision? The tourbillon cage eventually ends up having 142 parts! The rand name assures us that it is lighting enough to ensure that the keeping time is not affected. If which were true, they would never have eliminated ahead with it. After all, the entire idea of this “nano” idea is to demonstrate the ability to miniaturize mechanisms. So if I am not really completely convinced by the Foudroyante function here, the complexness and technical feat of the flying tourbillon is amazing in itself. high quality watches replica
The press release explains that certain of the highlights of this 10th fundamental invention is a “revolution in energy management”. Typically, the foudroyante is an energy-consuming mechanism, and GF’s miniaturization is once again impressive.
However , the report mentions that the power reserve is just 24 hours when the chronograph will be running, which sounds somewhat disappointing. We had to check this particular with the brand… They informed us that the power reserve is really about 40 hours, however the press release mentions a “chronograph power reserve” - twenty four hours, to ensure perfect timekeeping overall performance, and they encourage users in order to wind it correctly.
Now that we’ve discussed the foudroyante, I want to discuss this wonderful chronograph itself; the very first chronograph from Greubel Forsey! There’s almost no information within the press release, other than it states it’s a “manually wound flyback”. As if GF’s first timepiece was just a minor issue… replica Breitling Endurance Pro watches
Greubel Forsey’s very first chronograph should be big information, although what caught the eye was the succinct dimension, as the word “chronograph” is usually missing from the entire news release. The movement is just 31mm in diameter, so it is small enough to fit right into a nice mid-sized watch. This specific compact movement has 428 parts and is a by hand wound column-wheel driven flyback chronograph with a vertical clutch system. The movement offers a spectacular look of typical top-level Greubel-Forsey finishing; gorgeous chamfered edges, faces and bases. There are some difficult internal angles, yet they’re not too complex at first glance. Perhaps the chamfers within the long curves are more to be able to do by hand.
The case is made of white gold, using the bezel and caseback made from tantalum. The strap is definitely hand-sewn from nonanimal materials and features a white gold foldable clasp engraved with the brand’s GF monogram. replica Jacob & Co. epic x
