Clear Design: The New Armin Strom Pure Resonance

Armin Strom is known for maintaining a pared-down approach when it comes to watches. This ensures the brand’s style of watchmaking remains focused on its essence. And with every new model Armin Strom heads further in that direction and the new Pure Resonance is no exception. This version too heads further in said direction, squarely placing emphasis on the watch’s most remarkable feature: the visible dual balances oscillating in resonance.

The goal of the Pure Resonance has not changed: to display the interesting resonant balances while improving overall precision. To this end, the twin seconds flyback mechanism of Caliber ARF15 was removed and replaced with one clear-cut subsidiary seconds subdial. The reason for this can be found in the straightforward approach to the movement: the fewer functions a timepiece must perform, the better it can concentrate on accuracy. In other words, with no superfluous functions the watch con focus fully on precisely providing the time.

The dial now offers just subdials for time displays. Roman numerals dominate the off-center subdial displaying hours and minutes in black and blue with blued steel hands, while a classic railroad track marks the exact minutes. The smaller subdial at 7 o’clock displays seconds using only a baton-styled white hand and a simple track.
The resonators are placed at the left side of the dial. The time displays receive their portioned energy from the lower regulator, while the upper regulator remains in place to create resonance.

This conceptual forthrightness is reflected in the design of the movement: the basic calibre ARF16 showcases the resonant regulators and resonance clutch spring. New bridges are decorated with côtes de Genève. The mechanical movement beats at a frequency of 25,200 vph and provides a power reserve of 48 hours minimum.

The outward design of this new Pure Resonance has been kept also pure. The case has a diameter of 42 mm and comes in rose gold or stainless steel. It is 1.4 mm smaller than the original version, comes with reduced lugs and crown and practically no bezel. The characteristic lip at 6 o’clock remains, therefore it can be customized easily.
The case is water resistant up to 5 atm and comes with a leather bracelet.
