Armin Strom Tribute 3 Au750 turns rose gold into movement architecture

Armin Strom’s Tribute line has always been about compact proportions and an open view of mechanics, but the Tribute 3 Au750 takes that idea into more precious territory.

This limited edition uses 18K rose gold not only for the case and dial, but also for key architectural elements of the hand-wound movement, giving the watch a stronger visual link between exterior and calibre.

It’s a small run, a technically serious watch and a clear reminder that decoration can be structural rather than merely ornamental.

At a glance

Rose gold carries through the dial and calibre

The Tribute 3 Au750 measures 38 mm across and 9.38 mm thick, proportions that keep the watch firmly in dress-watch territory without hiding its mechanical intent.

Front and rear sapphire crystals are treated with anti-reflective coating, allowing the watch to present both its dial work and movement architecture clearly.

The off-centre dial is made from 18K rose gold and decorated with a radiating soleil guilloché pattern.

A surrounding surface carries a grain d’orge guilloché finish, giving the dial side two distinct textures before the eye even reaches the movement components.

Roman numerals keep the composition classical, while grey PVD-coated stainless steel Breguet-style hands introduce a cooler tone against the warmth of the gold.

Those hands are manufactured and hand-finished by Armin Strom, and they display hours, minutes and seconds.

A hand-wound movement with 100 hours of reserve

The watch is powered by Armin Strom’s in-house Calibre AMW21, a hand-wound movement measuring 33.5 mm in diameter and 4.2 mm thick.

It is made from 135 components, runs on 21 jewels and operates at 3.5 Hz, equal to 25,200 vibrations per hour.

The regulating system uses a flat hairspring and a variable-inertia balance wheel.

The 100-hour power reserve comes from a motor-barrel construction with reversed architecture.

In practical terms, the arbor winds the mainspring inside a fixed barrel drum, an arrangement that helps the movement preserve energy while remaining relatively slim and compact.

Armin Strom says 97 percent of the calibre’s components are produced in-house, a notable figure for a watch that places so much emphasis on visible construction.

Guilloché work gives the movement its character

The rose gold theme continues into the barrel, which sits under a mirror-polished 18K rose gold finger bridge.

On the back, a three-quarter bridge in 18K rose gold is decorated with clou de Paris guilloché.

Its hand-bevelled edges contrast with a grey PVD-coated mainplate, creating a defined separation between the warm gold structure and the darker movement surface.

The finishing palette includes hand-polished bevels, frosted surfaces, circular graining and black-polished screws.

Rather than relying on one decorative signature, the watch uses different treatments to separate functions, planes and textures across the movement.

Each Tribute 3 Au750 is assembled twice as part of Armin Strom’s production process, with the aim of checking both mechanical performance and finishing quality before final completion.

Details & Specifications

The Tribute 3 Au750 will appeal to collectors who prefer their precious metal watches with visible mechanics and restraint rather than excess.

Its strongest idea is simple and effective, taking rose gold beyond the case and making it part of the movement’s architecture.
