Masterpiece 2:
a world premiere

Minute Repeater Resonance by Armin Strom, the world’s first and only resonance chiming wristwatch, offers two-in-one for double the pleasure. Two complications, resonance and minute repeater; two vertically-stacked independent movements; two forms of resonance (oscillators and sound propagation); two independent mainsprings in one barrel; and two top development teams in Armin Strom (resonance) and Le Cercle des Horlogers (repeaters).

Inspired by the Bern’s centuries old chiming tower clock, the Minute Repeater Resonance is limited to just 10 pieces in celebration of the 10th anniversary of the Armin Strom manufacture. Masterpiece 2 highlights both the phenomenon of resonance and the sonorous chiming of the time by placing all of the action up front and center dial side.

Fully visible between the two oscillating balances is the patented Resonance Clutch Spring – the key to the mastery of resonance – and the result of three years of intensive research and development.

All components are finished to the very highest level, but of special note is the tremblage hand-engraving on the large golden balance cocks supporting the two oscillating balances. While titanium is the perfect metal for both transmitting the resonating sound from the gongs to the ear and ensuring that the watch is relatively light and comfortable to wear, it is a ‘cold’ metal; this coolness is balanced by the warm gold.

Under a virtually invisible sapphire crystal dial, the dual balances oscillating in synchronization and the two hammers striking the time, the Minute Repeater Resonance stages an unparalleled horological spectacle for both the eyes and the ears.

The Armin Strom Minute Repeater Resonance is a limited edition of 10 pieces in Grade 5 titanium in honor of the 10th anniversary of the manufacture. There will be no more editions.
