12:59 Anytime.

Armin Strom introduces the Minute Repeater Resonance 12:59 First Edition, a fully new development inspired by Masterpiece 2, expressed through entirely new proportions and mechanical architecture. 

 Click, to see the large size. ▶ BIG FOTO 

Engineered in a more compact 42 mm case, with a slimmer profile, while reaching a new level of mechanical complexity. Requiring meticulous attention to every component.

 Click, to see the large size. ▶ BIG FOTO 

This evolution is accompanied by a significant increase in mechanical intricacy. The striking system has been expanded from two to four hammers and four gongs, while a newly developed function introduces an additional level of interaction.

Through a dedicated selector, the wearer may choose between the conventional indication of time or activate the 12:59 sequence – the longest possible strike of the mechanism.

Beyond its technical advancements, the watch is defined by a singular design language, marked by purity of form and balanced proportions. While remaining fully openworked and three-dimensional, the composition is expressed with greater restraint, favouring softer lines and a more fluid architecture.

The resonance clutch has been reoriented to animate upward, bringing the oscillating interaction to the forefront, while the twin balance wheels remain visually anchored on the dial side.

The display is centred, reinforcing a strong sense of equilibrium, as the overall composition focuses on essential elements alone: the resonance system, the four hammers and gongs, and the visible flying governor regulating the cadence of the strike.

Conceived as a lasting expression of the complication, the design achieves a rare balance between mechanical intensity and visual harmony, while remaining unmistakably rooted in Armin Strom’s signature transparency.

Calibre ARR25: Setting new standards.

At the heart of the timepiece lies the entirely new manual-winding manufacture Calibre ARR25, developed, engineered and produced in-house.

Built around Armin Strom’s patented resonance clutch, the movement synchronises two independent regulating systems - each with its own barrel, gear train, escapement and balance wheel - operating in harmonic resonance.

 This dual architecture significantly increases mechanical complexity, requiring the precise coordination of twice the number of components found in a conventional striking movement.

  Click, to see the large size. ▶ BIG FOTO 

The minute repeater mechanism itself has been developed to match this level of sophistication. Equipped with four hammers and four gongs within a remarkably thin construction, the movement delivers a full Westminster chiming sequence.

A flying governor, visible on the dial side beneath the hammers, regulates the cadence of the strike, ensuring acoustic consistency and offering a dynamic visual indication.

A further innovation lies in the integration of the 12:59 function, allowing the wearer to select between two distinct striking modes. In standard operation, the watch chimes the time indicated by the hands. Alternatively, it delivers the longest possible sequence - 12 hours, three quarters and fourteen minutes.

 Click, to see the large size. ▶ BIG FOTO 

This transition is governed by a column wheel system, ensuring precision and reliability. The selected function is indicated via a discreet aperture (white / red), and activation is performed through a slider at 9 o’clock, which both winds and releases the striking mechanism.

Finishing, Tone by Tone.

Beyond its mechanical sophistication, the watch reflects Armin Strom’s commitment to hand craftsmanship.

Every component is meticulously finished by hand, with a complete 360-degree decoration by a dedicated in-house team.

On the dial side, the finishing reveals a balance between polished and matte surfaces. The hammers, gongs and resonance clutch spring are mirror-polished, contrasting with the frosted mainplate and bridges. Hand-bevelled edges, polished sinks, and refined textures enhance depth and definition.

The flying governor stands out as a focal point, combining hand-bevelled edges, circular graining, and a contrasting matte engraved surface.

ARMIN STROM – Mirrored Force Resonance – Ruby Edition

 

ARMIN STROM – RESONANCE Mirrored Force Resonance – Ruby Edition 2026

  Click, to see the large size. ▶ BIG FOTO 

A Living Stone: The Mirrored Force Resonance Ruby. 

A material shaped by nature. A movement crafted and hand-finished in Biel.

 Click, to see the large size. ▶ BIG FOTO

Armin Strom presents a new interpretation of the Mirrored Force Resonance, distinguished by a dial crafted from natural ruby - a gemstone prized for its vivid character and intrinsic vitality. Each dial is cut from genuine ruby, selected for the depth of its colour and the nuances only nature can create. 

 Click, to see the large size. ▶ BIG FOTO 

No two stones are identical. Fine inclusions and tonal variations are not imperfections, but signatures of authenticity - traces of a material formed over millions of years. The ruby introduces a vibrant mineral intensity that contrasts with the architectural symmetry of the resonance movement. 

 Click, to see the large size. ▶ BIG FOTO  

Its natural luminosity interacts subtly with light, revealing shifting red tones that bring warmth and presence to the exposed mechanics. Created in collaboration with a local stone artisan, this edition reflects Claude Greisler’s belief that materials must carry meaning beyond aesthetics. In ruby, symbolism and mechanics converge. 

 Click, to see the large size. ▶ BIG FOTO 

Ruby has always played an essential role in watchmaking. Within the movement, synthetic ruby jewels minimise friction and ensure long-term precision. On the dial, natural ruby asserts its presence - while engineered ruby ensures performance. 

 Click, to see the large size. ▶ BIG FOTO  

Housed in a 43 mm stainless steel case and paired with a grey Alcantara strap with white stitching, the Ruby edition delivers a powerful mineral presence. White printed Roman numerals complete the display, adding a classical counterpoint to the watch’s contemporary structural design.

Resonance, Perfected.

At the heart of the timepiece beats the manual-winding manufacture Calibre ARF21, entirely designed, developed and produced in-house. 

 Click, to see the large size. ▶ BIG FOTO 

Its patented Resonance Clutch synchronises two independent regulating systems, allowing the twin balance wheels to oscillate in harmonic resonance. 

 Click, to see the large size. ▶ BIG FOTO

The result is enhanced chronometric stability and long-term precision. A pusher at 2 o’clock resets both seconds counters simultaneously, offering a visual demonstration of the resonance phenomenon in action. 

 Click, to see the large size. ▶ BIG FOTO   

Operating at 3.5 Hz (25,200 vph) with a 48-hour power reserve, the movement transforms a centuries-old scientific principle into a modern mechanical achievement.

Designed to Matter.

The movement showcases Armin Strom’s approach to hand-finishing. Hand-polished bevels, black-polished screws, perlage and circular graining enrich the architecture, while Geneva stripes on the reverse enhance depth and contrast. 

 Click, to see the large size. ▶ BIG FOTO 

The interplay between the vivid ruby dial and the exposed mechanics creates a dynamic three-dimensional kinetic display. As with all Armin Strom timepieces, each watch is assembled twice to ensure both mechanical performance and finishing excellence.

Every surface is treated as an integral element of the overall composition, reinforcing the brand’s philosophy of transparent expression and artisanal precision.
