The Yellow Carbon Speed is our most striking build yet.
Most watches are built from stainless steel. This one is built from carbon composite — the same material used in Formula 1 chassis, aerospace components, and supercar bodies. Paired with a high-contrast yellow accent dial, the result is a chronograph that commands attention before you say a word.
Carbon Composite Case
Carbon fibre composite is used in the McLaren P1, Ferrari LaFerrari, and Lamborghini Huracán specifically because it offers extraordinary strength at a fraction of the weight of steel or aluminium. Your Yellow Carbon Speed applies the same principle to watchmaking — a case that is rigid, scratch-resistant, and ultralight.
On your wrist the difference is immediate. You feel it within seconds of putting it on.

Why Carbon?
The Hublot Big Bang, Richard Mille RM011, and Pagani Design RM series all use carbon composite cases for the same reason — they want the watch to disappear on the wrist while the dial commands attention.
Pair that with yellow speed accents and the result is a watch that nobody in the room is wearing — and everybody in the room notices.
