Welcome to our blog about the fascinating world of resonance technology in watchmaking. At Armin Strom, this extraordinary innovation combines traditional craftsmanship with cutting-edge engineering to create a unique timekeeping experience. In this article, we unveil three captivating facts that explain why resonance remains one of haute horlogerie’s rarest and most remarkable achievements. Dive into the artistry of independent Swiss watchmaking and discover the intricacies behind this phenomenon.
For the first time, the twin balance bridge is crafted from steel and designed with a flat surface that is hand-polished to achieve a mirror finish in accordance with the highest standards of traditional haute horlogerie decoration. This black polishing effect can only be achieved on steel.
The Dual Time GMT Resonance movement also offers a unique winding experience with a corresponding dial-side animation. The ratchet click system on the dial side of the timepiece provides this animation on the watch face, transforming the winding of the movement into a multi-sensory experience.
Unlike traditional click mechanisms connected to ratchets, the Dual Time GMT Resonance’s three-dimensional ratchet mechanism is connected to a pinion that is positioned between the two barrels to distribute the load more evenly. This two-part system consists of a bottom gear with Breguet teeth fixed to the main plate, and a top element with a spring connected to the axis. This approach provides more precise engagement and disengagement of the winding mechanism resulting in more consistent performance, more efficient energy transfer, reduced friction and wear on components, smoother operation and better overall durability for the winding system.
The functions remain the same as those in the Dual Time ‘Masterpiece 1’. However, fitting the movement into a 39mm case posed a significant challenge, requiring three years of development to create a completely new calibre – the 18th calibre developed by Armin Strom.
“Having two completely independent watch movements in a single timepiece creates the logical demand for an iteration that displays two time zones. The success of our first Dual Time inspired us to build a smaller and more elegant Dual Time Resonance watch. To do this, we further developed our concept and arranged the two movements vertically. And we couldn’t be happier with the result.”
