H. Moser & Cie Streamliner Tourbillon Pierre Gasly: Gold in Motion

When Formula 1 driver Pierre Gasly sat down with H. Moser & Cie., he didn’t play the ambassador lending a signature to a dial. He became a co-designer, selecting textures, insisting on mechanics, and shaping the watch like a continuation of his own taste. And the result shows it: this Streamliner is unmistakably Moser — and unmistakably Gasly.

What strikes you first is the combination of red gold and the chocolate fumé dial. Moser’s fumé work is already a signature, but this shade — warm, dense, almost smoky — was Gasly’s own choice. He wanted something that felt subtle from afar yet rich up close, a dial with presence but not theatrics. There’s a slight mystery to it, a soft tension with the clean lines of the 40-mm Streamliner case. Gold warms it, the gradient darkens it, and the transparent lacquer logo lets the color speak without interruption.

Inside, the watch is far more technical than its calm exterior implies. At six o’clock, the one-minute flying tourbillon pulls the eye with its constant, balletic motion — the very complication Gasly insisted on including. It makes sense: for a Formula 1 driver, precision and movement are not abstractions. A tourbillon is mechanical choreography; a car at speed is physics made graceful. Both rely on tolerances most people never think about.

The watch runs on the HMC 805 automatic calibre with a 3-day power reserve. It also features a double hairspring — designed and produced in-house by sister company Precision Engineering AG — which corrects positional errors and improves isochronism. In the world of high-end mechanical watchmaking, that detail is almost engineering made philosophy.

The collaboration produced two versions. The first, limited to 100 pieces, pairs the dial and red gold case with a chocolate-coloured rubber strap — a sport-chic balance that fits the Streamliner family. The second is the true rarity: 10 pieces only, with a fully integrated red gold bracelet and a discreet ruby set at ten o’clock, a nod to Gasly’s racing number. It’s the kind of detail you notice only if you’re paying attention — which is very much the point.
