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. 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.
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.
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.
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.
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.
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.
Turning the watch over reveals traditional finishing techniques such as Geneva stripes, straight and circular graining, alongside contemporary textures, creating a composition rich in detail, depth, and visual contrast.
