Inspired by Bern’s centuries-old chiming tower clock, the Minute Repeater Resonance highlights both the phenomenon of resonance and the sonorous chiming of the time. Under a virtually invisible sapphire crystal dial, the dual balance wheels oscillate in a resilient state of resonance as the two hammers strike the time, offering a simultaneous horological spectacle for both the eyes and the ears. As the world’s first and only resonance chiming wristwatch. It offers a one-of-a-kind experience to its owner.

A state of Resonance so
resilient that it can withstand
the gongs of a minute repeater

The Minute Repeater Resonance perfectly validates the resiliency of our unique architectural approach to resonance. The physical impact of the minute repeater gongs have no effect whatsoever on the stability of the resonance state that’s generated by the two balance wheels within the timepiece. They continue to operate in ‘anti-phase’ sympathy without disruption, even as the chiming gongs strike their targets. Titanium was selected as the perfect choice for transmitting the resonating sound from those gongs while ensuring that the timepiece is both light and comfortable to wear.

In keeping with its inclusion in our Masterpiece Collection, all components of the “Masterpiece 2” are hand-finished to the very highest level.  Especially noteworthy is the tremblage hand-engraving seen on the large golden balance cocks supporting the two oscillating balance wheels.

The Armin Strom Minute Repeater Resonance is a limited edition of 10 pieces in Grade 5 titanium; produced in honor of the 10th anniversary of the Manufacture.
