Some materials tell the time. Others tell a story. An aventurine dial captures the richness and mystery of a star-filled sky, and with the new Dual Time GMT Resonance Aventurine, we set it against the warm tones of our resonance movement. Cool light above, warm mechanics beneath: a watch built on contrast.
Aventurine is a material formed through a meticulous process that blends centuries-old glassmaking with modern precision. The result is a surface alive with light: a dial that evokes a night sky in motion.
The Dual Time GMT Resonance Aventurine (Ref. ST26-DT.CT). It combines an aventurine dial with two independent time zones and Armin Strom’s patented resonance technology, in a 39 mm stainless steel case, limited to 15 pieces.
Aventurine is not simply chosen, it is made. Centuries-old glassmaking traditions meet modern precision to create a surface that seems to hold light within it. Look closer and the dial comes alive: a night sky in motion, set in refined contrast to the architectural symmetry of the resonance movement.
On the Dual Time GMT Resonance Aventurine, the aventurine does not stand alone. Beneath the dial-side display sits a rose gold-coloured mainplate, adding depth. Rose gold-coloured hands and applied indexes introduce clarity and visual identity, while black azurage chapter rings complete the dial.
Together, these elements create a balanced interplay between cool luminosity and warm mechanical presence. The 39 mm stainless steel case and grey alligator strap offer a contemporary, restrained frame, allowing the dial and the symmetry of the movement to take centre stage.
Powering the watch is our manual-winding manufacture Calibre ARF22, entirely designed, developed and produced in-house. Its patented resonance clutch synchronises two independent regulating systems, allowing both balance wheels to oscillate in perfect harmony. This constant interaction elevates chronometric stability, turning a rare physical phenomenon into a practical advantage. (Curious how resonance works? Read our 3 Facts About Resonance Technology.)
Each time zone features its own hours, minutes and day/night indicator, offering intuitive functionality for travellers. Operating at 3.5 Hz (25,200 vph) with a 42-hour power reserve, the ARF22 unites scientific ingenuity with everyday usability.
Sapphire crystals on both sides reveal our signature open-worked architecture and hand-finishing. On the dial side, the mirror-polished balance bridge with hand-bevelled edges stands out as a focal point, its steel surface catching the light against the warm mainplate beneath. Rhodium-coated and steel components add a refined metallic grey, while hand-polished bevels, black-polished elements, circular graining and perlage enrich the composition.
On the reverse, matching rose gold-coloured gear-train bridges echo the dial side, while Côtes de Genève further emphasise the movement’s refinement. As with every Armin Strom timepiece, each watch is assembled twice to ensure both mechanical precision and finishing excellence. (More on our craft: 3 Facts About Decoration at Armin Strom.)
