Two Hundred Yellow Sapphires Around a Case.

In fine watchmaking, the tourbillon ceased to be a sufficient argument a decade ago. The great Houses folded it into their standard catalogues, and the market began searching for new frontiers. Jacob & Co. chose to answer from the world of jewelry: the Caviar Tourbillon Yellow Sapphires 44mm sets more than two hundred baguette-cut yellow sapphires along the entirety of its titanium case, while a floating tourbillon is exposed through a sapphire crystal.

The piece operates at the convergence of mechanical complication and precious material — a territory rarely entered by the great traditional manufactures of the industry.

Each sapphire requires hand-cutting, individual setting, and chromatic verification to ensure tonal uniformity. The movement, with its centralized suspension, performs as a functional sculpture within a continuous surface of stones.

In a segment where the client already owns multiple grand complications, the dialogue between high jewelry and fine watchmaking becomes the differentiating force that sustains both price and international demand.

When technique becomes democratized, exclusivity migrates toward artistic execution. This piece confirms that direction with more than two hundred stones and a mechanical signature that no competitor can replicate without years of specialized atelier work.
