Armin Strom has built its modern identity around resonance, but its newest complication adds a very different kind of theatre. The Minute Repeater Resonance 12:59 First Edition puts synchronized balances and chiming mechanics on open display, then adds a party trick serious collectors will immediately understand.
At a glance
- Armin Strom has introduced the Minute Repeater Resonance 12:59 First Edition with an in-house minute repeater integrated with its resonance system.
- The watch uses four visible hammers and four gongs for a Westminster chime, plus a dedicated mode that plays the full 12:59 sequence on demand.
- The 42mm titanium watch is limited to 25 pieces and priced at CHF 390,000.
The Armin Strom Minute Repeater Resonance 12:59 First Edition is a manual-wind, high-complication watch that combines hours, minutes, a minute repeater, and the brand’s spring-coupled dual-balance resonance architecture.
A minute repeater built for maximum theatre
Most minute repeaters are discreet by nature, hiding their hammers and gongs under a dial or behind the movement side.
Armin Strom takes the opposite route here, placing four hammers at 12 o’clock and the paired resonance balances at 6 o’clock, so the dial becomes a working display of sound and regulation.
The repeater uses four gongs and four hammers rather than the more common two-hammer arrangement, allowing it to play a Westminster-style chime for the quarters.
That matters because the complication isn’t just indicating time acoustically; it’s using a more elaborate musical sequence that gives the watch a broader tonal character.
The clever 12:59 demonstration mode
The name 12:59 isn’t decorative, because that setting produces the fullest possible sequence from a minute repeater.
At 12:59, the watch sounds 12 hour strikes, three quarter-hour chime sequences, and 14 minute strikes, making it the longest and most complete performance the complication can deliver.
Instead of asking the owner to set the hands to 12:59 and then correct the time afterwards, Armin Strom adds a dedicated demonstration mode that plays the full sequence on demand.
The selector sits at 9 o’clock on the case and also serves as the winding mechanism for the repeater, which gives the complication a practical interface rather than leaving it as a hidden flourish.
Resonance remains the mechanical signature
Armin Strom’s resonance system uses two balances connected by a flexible spring, allowing the oscillators to influence each other directly and gradually return to synchronization after disturbance.
It’s a different approach from traditional indirect resonance concepts, where two regulators interact through the shared structure of the movement rather than a dedicated coupling element.
In this watch, that system gives the repeater a second layer of mechanical interest, because the visual rhythm of the balances sits directly below the chiming works.
Titanium, salmon, and visible finishing
The 42mm case is made from titanium, keeping the large-complication format modern and relatively light on the wrist.
The salmon dial gives the watch warmth against the grey case, while the exposed components prevent it from becoming a conventional dress complication.
The four hammers are mirror polished and hand bevelled, a detail that matters because they sit front and centre every time the wearer looks at the dial.
For collectors, the appeal is clear: this is not simply a repeater with resonance added, but a watch designed to make both systems visible, audible, and easy to demonstrate.

FAQ
What is the Armin Strom 12:59 First Edition?
It’s a 42mm titanium high-complication watch that combines Armin Strom’s spring-coupled resonance system with an in-house minute repeater. The dial exposes the twin balances at 6 o’clock and four repeater hammers at 12 o’clock, making both the timekeeping and chiming mechanisms visible from the front.
How does the 12:59 demonstration mode work?
A minute repeater produces its longest possible chiming sequence at 12:59, with 12 hour strikes, three quarter-hour sequences and 14 minute strikes. This watch has a dedicated mode that plays that full sequence on demand, so the wearer doesn’t need to reset the hands to hear the complete performance.
What makes its minute repeater different from a typical repeater?
Most minute repeaters use two hammers and two gongs, while this Armin Strom uses four hammers and four gongs. That allows it to produce a Westminster-style chime for the quarters, giving the acoustic sequence a more complex musical character.
How does Armin Strom’s resonance system work in this watch?
The watch uses two balances linked by a flexible spring, allowing the oscillators to influence one another directly and return to synchronisation after disturbance. It’s a visible mechanical signature for the brand and sits at 6 o’clock beneath the chiming works.
How much does the Minute Repeater Resonance 12:59 cost?
The Minute Repeater Resonance 12:59 First Edition is priced at CHF 390,000. Production is limited to 25 pieces, and the confirmed configuration includes a titanium case, salmon dial and grey alligator strap with a titanium pin buckle.
