Jacob & Co. marks the tenth anniversary of its Astronomia line with the Revolution Fourth Dimension, a piece that shifts attention from ornate theatrics to pure mechanical mastery while preserving the collection’s dramatic spirit. The design pares back decorative elements in favor of a streamlined architecture that heightens the visual impact of its engineering. At the center is a pioneering quadruple-axis tourbillon that rotates on four distinct axes at accelerated speeds, a world-first configuration that enhances both spectacle and chronometric performance beyond traditional and even triple-axis systems. Powering this extreme kinematic display is an ultra-fast remontoir constant-force mechanism delivering six microscopic pulses per second. By equalizing torque to the escapement, it stabilizes precision despite the movement’s unusually high energy demands. The 47mm by 27mm case in 18K rose gold and sapphire crystal retains the Astronomia signature: panoramic views of the mechanism and an openworked structure. A polished, geometrically textured dial adds depth, creating a futuristic yet refined presence on the wrist. Limited to just 18 pieces and priced around USD 700,000, the watch embodies exclusivity, craftsmanship, and technical bravado—an object that appeals equally to connoisseurs of haute horlogerie and collectors of statement-making design. Its geometry and kinematics underscore how contemporary finishing and architecture can elevate traditional complications.
