ULYSSE NARDIN INNOVISION 2 (2017)
WHAT IT IS:
Unveiled in 2007, the first Innovision came packed with 10 technical advances, several of which paved the way for movement-improving mechanisms such as Ulychoc, a novel monobloc shockabsorption system constructed entirely in silicon. A decade later, Ulysse Nardin reveals the Innovision 2, a follow-up that – like its predecessor – features 10 technical innovations.
The Dual Constant Escapement combines elements from two existing Ulysse Nardin escapements – the Dual Direct Escapement and the Ulysse Anchor Escapement – for greater efficiency and better isochronism. Simply put, this constant-force escapement lets the watch run longer on a full wind, while remaining accurate as its mainspring runs down.
Also new is a skeletonised balance wheel with four gold weights on its rim, a design that maximises the balance’s inertia as it oscillates, yet minimises the overall mass of the system – again for precision and efficiency. “Paddles” at the end of the balance wheel’s “spokes” smooth out air turbulence within the watch case as the balance oscillates. Finally, a hyper-efficient self-winding mechanism, dubbed “Grinder”, uses springs, ratchets and ballbearings to utilise the tiniest movements of the wrist for winding the mainspring.
Although a new balance and escapement may be costly and limited to more technically focused watches in the near future, the Innovision 2 contains plug-and-play features that can be implemented in regular production watches easily, such as Grinder – we’ll just have to wait and see.
