Watchmaking is a complicated affair, especially when you get into the realm of advanced physics – a tourbillon offsetting the effects of gravity for example. Armin Strom however has taken it further, incorporating the concept of mirrored force resonance.
At the most basic level, mirrored force resonance in watchmaking is the idea that when two balance wheels oscillate near one another, they will sync up for greater stability. This in turn translates to greater accuracy and overall performance.
Needless to say it’s a pretty rare complication. F.P. Journe and Haldimann are the only two that come to mind straight away. Not that this is Armin Strom’s debut of the movement; last year’s ‘Fire’ version showcased it in rose gold.
This new steel version is more affordable, rugged and, most importantly, stunning. A good part of that is thanks to the dial which has replaced black and gold with white and blue, giving the whole piece a cleaner, more minimal look.

The resonance concept is represented by two independent second hands (both of which can be set with a single pusher) allocated to the two balance springs. Those three-spoked hands combined with the open-worked section of the dial are hard to take your eyes off.
Limited to 50 pieces worldwide, the Mirrored Force Resonance Water illustrates an immensely complicated concept in a beautifully simple way. Between the white and blue dial, steel case and mesmerising movement, it’s also simply beautiful.
