Sector Chronograph Aventurine 324.444

Aventurine isn’t just a color — it’s depth: stardust suspended in glass, alive under changing light. In this chronograph, that beauty comes with real engineering: hollowed-out counters and a dial built on a brass base, topped with two identical aventurine layers—matched, bonded, and aligned to create a true multi-level structure. Framed by the disciplined geometry of a sector chronograph, and finished with BGW9 lume on hands, numerals, and the sector print, it’s poetic in daylight and uncompromisingly legible at night.

The inaugural batch of the Heritage Sector Chronograph Aventurine has now sold out.

Production has commenced, with first deliveries expected from September 2026. You can now register your interest for the next production batch.

DESCRIPTION

The Heritage Sector Chronograph Aventurine pairs classic chronograph architecture with a dial that feels alive. Its aventurine dial—deep blue glass filled with countless shimmering particles—catches light like a night sky, shifting from subtle sparkle to a full “starfield” with every movement of the wrist.

This is also a notably complex aventurine execution. To create the chronograph’s hollowed-out counters and multi-level depth, the dial is engineered as a layered construction: a rigid brass base topped with two identical aventurine layers, carefully matched, bonded, and precisely aligned. The result is the visual drama of recessed sub-dials, achieved with a material that demands careful handling and absolute precision.

The sector layout brings calm clarity—concentric rings, crisp numerals, and an instrument-style scale that makes elapsed time instantly legible. And when the lights go down, readability takes the lead: BGW9 Super-LumiNova illuminates the hour and minute hands and the numerals and sector print, preserving the dial’s structure in the dark.

Aventurine glass, built for a chronograph

Aventurine (sometimes called “goldstone”) is a glass material known for its signature sparkle—tiny metallic crystals suspended within the glass that flash and fade as the light changes. For a time-only dial, that beauty is already compelling. For a chronograph with recessed counters, it becomes a technical challenge: the material must be cut thin, kept stable, and assembled with absolute precision.

Venice and Murano are part of aventurine’s long cultural story, but our focus is what matters on the wrist: optical depth in daylight, and a dial architecture engineered to last.

Inside the sparkle

Seen as a raw piece, aventurine reveals what a finished dial only hints at: a dark, glassy body threaded with countless points of light. The sparkle isn’t printed or coated—it’s internal. Each reflective particle catches light at a slightly different angle, which is why aventurine never reads as a flat “blue”. It behaves more like depth than color.

From slates to a multi-level dial

To achieve true recessed chronograph counters, the dial is constructed as a layered assembly rather than a single sheet. A rigid brass base provides long-term stability and dial feet, while two identical aventurine slates are matched and aligned on top:

  • Bottom slate: 0.40 mm
  • Top slate: 0.35 mm
  • Mounted on a brass base for rigidity and precise positioning

Working aventurine at these thicknesses demands careful cutting, finishing, and bonding—any stress can compromise the surface or alignment. The payoff is a dial with real depth: hollowed-out counters, crisp geometry, and the unmistakable sparkle of aventurine preserved across the entire structure.

Printed geometry, luminous clarity

Once the layered aventurine structure is complete, the dial receives its final layer of precision: the sector geometry itself. Concentric tracks and crisp numerals are applied to frame the chronograph layout and sharpen readability—turning the dial’s depth into a clear instrument-like display.

And when light fades, the structure remains. BGW9 Super-LumiNova is applied not only to the hour and minute hands, but also to the numerals and the sector print, so the full layout stays legible in the dark—cool, clean, and unmistakably sector.

A Venetian craft, reinterpreted

A historical illustration of the Doge of Venice visiting the Murano glassworks (Louis Figuier / Jules Férat).
Aventurine is often linked to Venice’s historic glassmaking tradition, where experimentation in the furnace gradually became repeatable craft. That legacy matters—not as nostalgia, but as a reminder that some materials still demand time, precision, and experience. On this dial, the tradition is reinterpreted through modern watchmaking constraints: thin sections, stable mounting, and chronograph-level tolerances.
