18K rose gold is presented for the first time in Armin Strom's Tribute³ Au750: from the case to the dial and off-center subdials, and even in the caliber itself.

The three bridges of the movement are made of solid gold, and the barrel and balance feature the characteristic finger-shaped construction along with the three-quarter bridge. In this way, gold becomes an integral part of the architecture of the movement.

But the material is only part of the story. Three guilloché motifs give three different expressions to the gold: a radiant sun pattern on the off-center dial, gold grain on the subdial, and a clou de Paris pattern on the three-quarter bridge visible through the caseback. The model has a diameter of 38 mm, with a height of 9.38 mm.

Together, they bring craftsmanship to the forefront for the first time in the Tribute³ Au750. Gray PVD-coated stainless steel Breguet-style hands also debut on this model. The Roman numerals complete a watch firmly rooted in the codes of fine watchmaking.

Designed and developed entirely in-house, the manually wound caliber AMW21 embodies Armin Strom's pursuit of clarity and mechanical efficiency. Its high-efficiency motor barrel, with an inverted architecture, allows the shaft to wind the mainspring inside a fixed drum. This compact construction contributes to an impressive 100-hour power reserve, while allowing the caliber to retain a remarkable compactness. With 97% of its components manufactured by Armin Strom, the AMW21 caliber is a true expression of the Manufacture's independence.

Gold alone was never the important thing. It is through the métiers d'art that the watch finds its character. On the dial, the visible barrel sits under a mirror-polished rose gold bridge. Turning the watch, the three-quarter bridge takes center stage, with its clou de Paris guilloché pattern and hand-beveled edges standing out against the gray PVD-coated main plate. The contrast highlights the geometry of the guilloché and the architecture of the caliber.

From the perfect reflection of mirror polish to the geometric precision of guilloché, each technique reveals a different facet of gold. Hand-polished bevels, frosted surfaces, circular graining, and black polished screws add additional layers of traditional craftsmanship. As with all Armin Strom watches, each Tribute³ Au750 is assembled twice to ensure both mechanical precision and excellence in finishing.

Limited to 8 units, it comes with a gray nubuck leather strap with gray stitching and 18K rose gold buckle.
