Here’s a nutshelling of Greubel Forsey’s Nano Foudroyant EWT mechanism, which might just change watchmaking as we know it

Behold Mechanical Nano from Greubel Forsey, quite possibly haute horlogerie's version of reinventing the wheel. In what has been a project 10 years in the making, the maison has debuted Nano Foudroyant EWT — an acronym that spells Experimental Watch Technology — following intense research from their R&D labs on the mastery of nano-energy for horology. The first of its kind, Mechanical Nano is a breakthrough mechanism that allows clockwork to be shrunken down to even smaller proportions, because wouldn't you know it, power needed to drive a wristwatch movement has been a limiting factor when it comes to design and innovation.

To give you an idea of the magnitude of this invention, let's just say Nano Foudroyant EWT is shaking up four centuries worth of haute horlogerie history. By applying the concept of nano-energy in a watch mechanism, Greubel Forsey has completely rethought the mechanism of the traditional foudroyant jumping seconds with a new construct, featuring a very low moment of inertia, extremely efficient energy consumption — we're talking nanojoules — and even do away the need for a full gear train. But if all this banging on about nano everything is going over your head, here are the three talking points you need to know on how it'll affect you and your watch:

With the inertia reduced, more energy is saved and directed to the functions of the watch. Practical lab tests have come back with numbers that show an optimisation of energy, which leads to various innovative possibilities like a watch with a 180-day power reserve. That Greubel Forsey is in the works researching and developing to make into reality, by the way.

Up to a boggling 96 per cent less compared to a conventional mechanism, in fact. For the Nano Foudroyante EWT specifically, it comes equipped with a miniature hand, though you can put tiring, squinting issues to bed because the read-off is as clear as ever with a 23x magnification optical system.

The Mechanical Nano, and in turn the Nano Foudroyante EWT, have been patented, creating a truly original and innovative foudroyant jumping seconds mechanism. One that makes the best use of energy and available space in the movement of a mechanical timepiece, and is nothing short of disrupting the status quo.
