Armin Strom Tribute2 Aurum – tremblage with intent

The Armin Strom Tribute2 Aurum builds on the Tribute 1 and trims away more metal to show its mind at work. More openworked and more skeletonised, it frames a gold coated mainplate in brass finished by hand with the rare tremblage technique. The surface is alive with a fine, irregular grain that catches light rather than chases it. A grey fumé off-center dial hovers in the layered construction, giving calm order to the architecture beneath.

Inside is the hand-wound AMW21, developed and manufactured entirely in-house. It promises a 100-hour power reserve thanks to an innovative motor barrel in which the arbor drives the gear train. The layout saves space and favors efficiency. The calibre runs at 25,200 vibrations per hour at 3.5 Hz and employs a variable inertia balance wheel with a flat spring, all set under the brand’s System 78 signature finger bridge.

The front shows a skeletonised motor barrel with hand-polished, bevelled spokes and a black-polished, bevelled steel finger bridge. It is an honest way to display energy storage and transmission – no theatrics, just crisp surfaces meeting clear edges.

Turn it over and the movement settles into tradition with a three-quarter bridge featuring Geneva stripes and circular graining. The 60° hand-polished bevel is the quiet flourish that matters, while a three-dimensional escapement wheel bridge with a polished sink adds a measured sculptural note. Each piece is assembled twice, which reads less like ritual and more like respect for the work. Limited to 10 pieces, the Tribute2 Aurum speaks softly, letting tremblage texture and open structure do the talking.
