A technical duet: resonance meets chiming complication
Eight pieces. Swiss Francs 360,000 each. The Minute Repeater Resonance 12:59 First Edition is Armin Strom’s most ambitious mechanical synthesis: twin balances linked by the brand’s clutch spring sit alongside a fully integrated minute repeater. The result reads as both an acoustic instrument and a precision chronometer.
Case, dial and first impressions
The watch wears a 45 mm platinum case with satin-brushed and polished surfaces and measures a surprisingly manageable 13.3 mm thick despite housing cathedral gongs and a repeater mechanism. A layered sapphire dial exposes the twin balances, clutch spring and the striking gongs, while a hand-finished subsidiary seconds and a power-reserve indicator keep the display clear and elegant.
Movement details and acoustic engineering
Calibre ASR-21R powers the piece. It is a hand-wound movement with two independent regulators coupled by the signature clutch spring to encourage resonance, twin mainspring barrels that supply around 72 hours of autonomy, and a dedicated striking train for the minute repeater. Acoustic choices are deliberate: cathedral gongs are affixed directly to the case band and tuned by hand, and a silent centrifugal governor controls strike speed. Armin Strom says the resonance system improves timing stability while the repeater is engaged — a solution that required extensive prototyping to prevent the chiming train from disturbing the synchronized oscillators.

Why collectors will notice it
Resonance aims at chronometric stability. A minute repeater tests acoustic purity and finishing. Putting both on a single wristwatch shifts the conversation from single-discipline bravado to cross-disciplinary engineering. For collectors this First Edition offers rarity, visible movement architecture and a clear narrative of technical originality.
“This piece is less about loud declarations and more about proving that two demanding disciplines can coexist beautifully on the wrist,” an insider involved in the project told us.
Availability will be tightly controlled. The eight-piece run is scheduled to be offered directly through Armin Strom boutiques and selected partners starting in the third quarter, with owners able to commission bespoke dial finishes as part of the commissioning process. If you prize mechanical originality over logo-driven cachet, open a dialogue with the brand now — demand will outstrip supply, and this model is likely to be one collectors single out when chasing technical firsts.
