This is the ultra-limited edition of the Streamliner Tourbillon Pierre Gasly, a piece deeply personal to the F1 maverick. It pays tribute to his racing number, 10 — a constant throughout his career — symbolised by a single red ruby set discreetly at ten o’clock above the rich Chocolate fumé dial. Set in a 5N red gold Streamliner case, it features a one-minute flying tourbillon, chosen by Pierre and powered by the automatic HMC 805 calibre with a double hairspring designed and produced in-house. Limited to just 10 pieces, it comes with a fully integrated 5N red gold bracelet that flows seamlessly from the case, creating a continuous, organic silhouette. A perfect ten, in every sense.
