Greubel Forsey not too long ago unveiled an experimental watch designed utilizing superior nanomechanics.
The Nano Foudroyante EWT is the world’s first perpetual Nano Foudroyante — and represents the primary time Greubel Forsey has created a flying tourbillon. This flying tourbillon is extra subtle than most and uniquely options an embedded foudroyante mechanism. There’s additionally a 60-minute flyback chronograph.
As you count on with Greubel Forsey, the whole lot is completed to the very best degree doable, together with the 18K white gold caseband with hand-finished straight-graining. The tantalum bezel is polished by hand, and the caseback consists of a tantalum ring with a flat sapphire crystal secured by 7 screws. The conservatively sized case measures 37.90 mm in diameter by 10.49 mm thick, has a domed sapphire crystal, and is water resistant to a depth of 30 meters (ISO 22810:2010).
Greubel Forsey’s Nano Foudroyante dial has a multi-level gold building with rhodium-colored, engraved, and black lacquered markings — which exude the celebrated match and end clients demand at this value level.
The Nano Foudroyante EWT is powered by a 3Hz, hand-wound, 428-component motion (142 for the tourbillon cage) and is protected by 2 patents. With 42 olive-domed jewels set in gold chatons, circular-graining, polished bevels, frosted surfaces, flat polished screw-heads, straight-grained flanks, and engraved GF brand — each element is immaculately embellished to Haut de Gamme requirements.
Based on Greubel Forsey, “To reveal the feasibility of nanomechanics, Greubel Forsey has reinvented the foudroyante second. Its hand completes one revolution per second, dividing it into segments in keeping with the motion’s frequency. On this Nano Foudroyante, every oscillation of the 3Hz steadiness wheel produces two beats, totaling six beats per second, permitting the hand to divide the second into six distinct segments. That is an energy-intensive complication by nature. Nonetheless, by managing vitality on a nanojoule scale, Greubel Forsey has radically rethought its design and building. In comparison with a conventional foudroyante that consumes 30μJ (microjoules) per bounce, the Nano Foudroyante operates with solely 16nJ (nanojoules) per bounce, lowering vitality consumption by an element of 1,800. The mechanism’s quantity is due to this fact decreased by 90%. Right here, the main target isn’t just on measuring fractions of a second however as a proof of idea for a very new strategy to watchmaking, which is why this Nano Foudroyante was chosen to be a perpetual show. It eliminates your complete gear practice required in a conventional foudroyante to divide the second, as the data is sourced instantly, distributing and managing the vitality from the motion via a minimal variety of low-inertia wheels. Fewer elements imply much less quantity: this Nano Foudroyante EWT could be very compact, with 428 elements, and the motion measures not more than 31mm in diameter inside a 37.9mm case (the smallest ever constructed by Greubel Forsey).”
Greubel Forsey paired every watch with a hand-sewn black textile strap with an 18K white gold pin buckle and hand-engraved GF brand. Restricted to 11 items, the Nano Foudroyante EWT is the horological equal of an experimental Ferrari.
