Armin Strom Tribute 3 Au750: 18K rose gold from case to calibre

Armin Strom Tribute 3 Au750 combines 18K rose gold case and movement with three guilloché patterns. Price CHF 69,000

Armin Strom has unveiled the Tribute 3 Au750, a new interpretation of the Tribute model in which 18K rose gold extends from the case and off-centre dial into the architecture of the movement. 

Limited to eight pieces, the watch combines three distinct guilloché patterns with the Manufacture’s hand-wound Calibre AMW21.

Measuring 38 mm in diameter and 9.38 mm in height, the Tribute 3 Au750 is equipped with front and rear sapphire crystals featuring anti-reflective treatment.

The compact case frames an off-centre 18K rose gold dial decorated with a radiating soleil guilloché pattern and Roman numerals. The surrounding surface is decorated with a grain d’orge guilloché pattern. 

Grey PVD-coated stainless steel Breguet-style hands, manufactured and hand-finished by Armin Strom, provide the hours, minutes and seconds indications. Their darker finish contrasts with the warm tone of the gold and the textured surfaces of the dial.

Gold continues into the visible barrel, held beneath a mirror-polished 18K rose gold finger bridge. 

The reverse offers a view of the three-quarter bridge, also crafted from 18K rose gold and decorated with a clou de Paris guilloché pattern. 

Its hand-bevelled edges stand out sharply against the grey PVD-coated mainplate, establishing a clear visual separation between the warm gold structure and the darker surfaces of the movement.

The movement combines several traditional finishing techniques. 

Alongside the guilloché work and mirror polishing, the finishing includes hand-polished bevels, frosted surfaces, circular graining and black-polished screws. 

The different treatments give the movement a varied surface texture while keeping its architectural elements clearly defined.

Entirely in-house designed and developed, the hand-wound Manufacture Calibre AMW21 measures 33.5 mm in diameter and 4.2 mm thick. It comprises 135 components and 21 jewels and operates at a frequency of 3.5 Hz, or 25,200 vibrations per hour. 

Its regulating system combines a flat hairspring with a variable-inertia balance wheel.

The movement achieves a 100-hour power reserve through a motor-barrel construction with a reversed architecture. 

This arrangement allows the arbor to wind the mainspring within a fixed barrel drum, making efficient use of the available space while keeping the movement relatively compact.

Remarkably, 97% of the calibre’s components are produced entirely in-house by the Manufacture.

As with every Armin Strom timepiece, the Tribute 3 Au750 is assembled twice as part of the brand’s production process. The approach is intended to verify both the mechanical performance and the quality of the finishing before the watch is completed.

Water resistance is rated at 5 ATM, equivalent to 50 metres (165 feet). The Tribute 3 Au750 is fitted with a grey nubuck leather strap with grey stitching and an 18K rose gold pin buckle. The lug width is 18 mm.

Reference RG26-TRI.AU is limited to eight pieces worldwide and retails at CHF 69,000. arminstrom.com
