Armin Strom Tribute³ Au750: Solid Gold Bridges in an Edition of Eight

Armin Strom Tribute³ Au750 (ref. RG26-TRI.AU): 18K rose gold case and movement bridges, three guilloché patterns, 100h power reserve. Limited to 8 pieces, CHF 69,000.

The Salient Points

• Three solid 18K rose gold movement bridges — barrel bridge, balance bridge, and three-quarter bridge — each bearing a distinct guilloché pattern, define reference RG26-TRI.AU as the first Tribute to carry the material deep into the calibre architecture.
• Calibre AMW21 is a manual-winding manufacture movement with a 100-hour power reserve, produced at 97% in-house by Armin Strom in Biel/Bienne.
• Three guilloché decorations are deployed across the piece: soleil on the off-centre dial, grain d’orge on the subdial, and clou de Paris on the three-quarter bridge.
• The edition is strictly limited to eight pieces at CHF 69,000.

Design & Mechanics

Gold on previous Tribute references defined the case and dial. On the Au750, it extends into the movement itself. All three bridges of Calibre AMW21 are machined from solid 18K rose gold, making the material load-bearing as well as decorative. The visible motor barrel sits beneath a mirror-polished rose gold finger bridge on the dial side; turn the watch over and the three-quarter bridge occupies the caseback view, its clou de Paris guilloché and hand-bevelled edges offsetting the grey PVD-coated mainplate beneath.

Grey PVD stainless steel Breguet-style hands, manufactured by Armin Strom, appear on the model for the first time. Against the Roman numerals and the warm gold surfaces, they provide exactly the contrast the dial needs without cluttering the view of the movement.

Movement & Materials

Calibre AMW21 measures 33.5 mm × 4.2 mm and runs at 3.5 Hz with 21 jewels across 135 components. Its reversed motor barrel architecture — the arbor winds the mainspring within a fixed drum — keeps the calibre compact while achieving a 100-hour power reserve. Armin Strom produces 97% of the movement’s components in-house, a degree of integration that few independent houses in Switzerland can claim at this price level.

The fine watchmaking métiers d’art deployed here extend beyond guilloché. Hand-polished bevels, frosted surfaces, circular graining, and black-polished screws layer the finishing across both sides of the movement. Each Tribute³ Au750 is assembled twice — once to verify mechanical performance, once to confirm finishing standards — before leaving the manufacture.

Market Position

Eight pieces at CHF 69,000 positions the Tribute³ Au750 squarely in the territory of small-series independent manufacture watches where secondary market scarcity is structural rather than speculative. The case diameter of 38 mm and lug-to-lug of 18 mm give it a presence on the wrist that reads as a dress watch — relevant for collectors in the Gulf who wear watches to formal engagements and business meetings alike, where restraint in dimensions carries its own signal.

Why Collectors Care

At eight pieces, allocation is the principal constraint. Collectors who follow Armin Strom will note that this reference, RG26-TRI.AU, marks the first time the Tribute family has unified material, decoration, and architecture across both dial and movement in a single proposition. That coherence — gold not applied but integrated — gives the watch a narrative collectors and auction specialists can articulate clearly, which matters for long-term value.
