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.

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.

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.

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.

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.

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.

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.

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.

ARMIN STROM – TRIBUTE² Aurum Edition

 

ARMIN STROM – System 78 TRIBUTE²– Aurum Edition 2026

 Click, to see the large size. ▶ BIG FOTO 

The Tribute² Aurum marks a sophisticated evolution in Armin Strom’s lineup, bringing a new level of refinement to its dual-dial skeletonized movement. 

Click, to see the large size. ▶ BIG FOTO 

Encased in 18k rose gold, this limited edition highlights the brand’s unwavering commitment to hand-finished precision and avant-garde horology.

A New Tribute, A New Texture.

Building on the foundation laid by the Tribute 1, the Tribute² Aurum Edition pushes the limits of artisanal decoration. More openworked and skeletonised than its predecessor, this edition enhances the architectural presence of the movement while revealing even more of the hand-finished detail that defines the collection. 

Click, to see the large size. ▶ BIG FOTO 

A gold coated mainplate, crafted from brass and finished by hand with the rare tremblage technique, sets the stage with a rich texture and depth. Paired with a grey fumé off-center dial and layered construction, the design invites a deeper appreciation of contrast, craft and dimensionality. 

The Pulse of Independent Watchmaking.

The hand-wound AMW21 movement, developed and manufactured entirely in-house, delivers an impressive 100-hour power reserve. 

Click, to see the large size. ▶ BIG FOTO 

This performance is made possible by the movement’s innovative motor barrel construction, in which the arbor delivers the energy to the gear train – a configuration that improves efficiency while optimising space within the movement.

Operating at a frequency of 25,200 vibrations per hour (3.5 Hz), the calibre features a variable inertia balance wheel and a flat spring, supported by the system 78 signature finger bridge.

Decoration, Elevated.

True to Armin Strom’s artisanal ethos, the Tribute² Aurum is an ode to hand-finishing at its highest level. 

Click, to see the large size. ▶ BIG FOTO 

The centrepiece is its gold coated tremblage finished mainplate – a rare engraving technique that reflects light with an irregular texture, adding vibrancy and depth. The front side showcases a skeletonised motor barrel with hand-polished bevelled spokes as well as a black-polished, bevelled steel finger bridge.

On the back, the movement reveals a three-quarter bridge with Geneva stripes and circular graining, but it’s the 60° hand-polished bevel that elevates it as a tribute to craftsmanship.

A three-dimensional escapement wheel bridge with a polished sink adds a sculptural flourish. Each Tribute² Aurum is assembled twice, a hallmark of the brand’s commitment to mechanical precision and aesthetic integrity.

 Armin Strom: A fully integrated manufacture

While Armin Strom is a vertically integrated, complete horological manufacture, no new watch movement would ever have seen the light of day were it not for Claude Greisler, who puts ideas such as the one for the revolutionary Mirrored Force Resonance movement down on paper before they are transferred to computer-aided design programs to start modelling the movement. Like so many things at Armin Strom all of this is done in-house, with the dimensions calculated down to a precision of one micron to provide the inputs for the machines that will eventually produce the smallest of components. 

Click, to see the large size. ▶ BIG FOTO 

Claude Greisler

At Armin Strom, the majority of components in the movement, with the exception of the escapement and balance spring, are produced in-house. Small round components like screws, pinions and gear wheels are produced by profile-turning machines, which gradually whittle away long steel or brass rods from the side to cut teeth or axles. Larger components such as base plates and bridges are produced from brass on CNC machines, which are capable of machining along multiple axes consecutively using different tools for different operations, moving the component using robotic arms.

Tiny and delicate components, such as smaller bridges, levers and springs, are produced using wire erosion. This involves threading a wire that is not much smaller than a human hair through a tiny hole in the metal. An electrical current running through the wire reacts with a solution in which the entire working plate is dipped, thus “eroding” minuscule amounts of the metal. This allows particularly delicate operations to be carried out while maintaining the structural integrity of the metal. Armin Strom does not produce any of its components by stamping because of the stresses that this places on the metal.

Once the raw components are manufactured, they are engraved, beveled, polished and decorated with circular graining or Geneva stripes by hand before moving to the in-house electroplating department. Here, all steel and brass components are first given a gold plating before a layer of nickel is added to prevent corrosion and harden the surface. After cleaning, the parts are then dipped in other electroplating baths to give them their final color such as rhodium, ruthenium, or rose gold. It is only thanks to its mastery of electroplating techniques inside its own workshops that Armin Strom can allow customers to choose preferred colors for the coating on different components.

Only then can the individual components of the movement be passed on to the watchmaker for assembly. After setting the jewels into the base plate and bridges, the watchmaker adds the gear train and mainspring. After the escapement and balance wheel are positioned, the movement finally comes to life…only to be completely disassembled, cleaned, and dried before being re-assembled and lubricated. After several days of testing the precision, the watch is finally ready.
