In accordance with high-end Swiss watchmaker Greubel Forsey, its novel “Nano Foudroyante” mechanism is a game-changer in mechanical timekeeping. Launched to have a good time its twentieth anniversary, the Greubel Forsey Nano Foudroyante EWT not solely introduces the model’s new foudroyante mechanism but in addition marks the model’s first flying tourbillon and the primary chronograph. However what’s particular in regards to the namesake nano foudroyante?
Hardly ever do manufacturers talk about why they embrace a foudroyante mechanism in a watch, as a result of the truth is that nowadays they’re largely for visible enjoyable. We’ve seen foudroyantes or related gadgets from Jaeger-LeCoultre, Zenith, and F. P. Journe, amongst others, and there’s all the time a sense of, “That’s neat, however why?” A standard foudroyante manifests itself with a really fast-moving hand that normally strikes six positions in a single second, relying on the working frequency of the regulation system. Their objective is usually associated to measuring the accuracy of a chronograph, however on this occasion, the mechanism appears to run on a regular basis and isn’t related to the chronograph – which does exist within the watch. Greubel Forsey’s Nano Foudroyante hand rotates on the regular foudroyante fee, however the innovation is that the model diminished its power consumption by an element of 1.8, permitting the mechanism’s measurement to be diminished by 90% based on firm. Greubel Forsey has additionally created a novel system whereby the small foudroyante dial is mounted on the flying tourbillon and is geared such that it all the time stays “upright,” even with the spinning of the tourbillon. To position a foudroyante show that all the time stays upright on a spinning 60-second tourbillon cage was little question difficult, although it primarily advances the artwork of horology extra so than the practicality of it.
Greubel Forsey is barely producing 11 items of this model of the Nano Foudroyante and makes it clear {that a} watch like that is “Experimental Watch Know-how,” therefore the EWT within the title. By decreasing the dimensions of the foudroyante, the model was in a position to make use of the smallest case it has ever produced, measuring a number of millimeters narrower than most of its timepieces. The case is barely 37.9mm extensive and 10.49mm thick, is water-resistant to 30 meters, and comes on some unspecified “non-animal” strap materials. And whereas it might be the smallest watch the model has produced, it definitely gained’t be the lightest: The case is created from 18k white gold with a tantalum bezel.
Greubel Forsey’s Nano Foudroyante EWT additionally has a chronograph, which it barely mentions as a part of the Nano Foudroyante’s launch. The 60-minute chronograph (operated with the two o’clock pusher and the crown pusher) has a central seconds hand and a subsidiary chronograph minute counter on the left facet of the dial. Below that could be a small dial that operates as a working second indicator. Notably (and never for the primary time), Greubel Forsey has utilized a purple triangle indicator to the rotating tourbillon ring, although these are curiously not in sync within the press pictures.
The motion is produced from 428 elements and operates at 3Hz (21,600 vph). One notable aspect right here is the ability reserve: Greubel Forsey solely gives the ability reserve with the chronograph engaged and says that’s simply 24 hours (“one full day”). That’s a far cry from GF’s typical 72 hours, in addition to what most shoppers anticipate nowadays. It isn’t clear what the ability reserve of the Nano Foudroyante watch is with out the chronograph working, nevertheless it wouldn’t be for much longer. It’s in all probability vital to keep in mind that this watch is explicitly “experimental,” and as such, could also be higher regarded as a proof of idea than the ultimate product. The motion is, after all, completed to the model’s exceptionally excessive requirements.
In some ways, the Nano Foudroyante EWT tourbillon watch is revolutionary and fascinating to speak about. It captures the essence of Greubel Forsey whereas providing each a brand new motion and a brand new carrying expertise. True to the title, the watch is experimental, and thus meant for fans who wish to attempt new (and really costly) issues. It isn’t probably the most refined or high-performance Greubel Forsey round, neither is it clear what sensible efficiency advantages the motion has. That stated, the visible motion of the dial needs to be very spectacular, particularly with the chronograph working and all of the arms shifting at seemingly completely different charges. Greubel Forsey will solely make 11 items of this model of the Nano Foudroyante EWT with the 18k white gold and tantalum case with the silver dial. My suspicion is that there will likely be a couple of extra variations earlier than this idea exits the experimental section. The Greubel Forsey Nano Foudroyante EWT watch is priced at CHF 465,000.
