The Classic Fusion 581.CM.1470.RX, seen from the bench

The Hublot Classic Fusion 581.CM.1470.RX embodies Art of Fusion philosophy with a 42mm case in technical ceramic and resin housing the HUB1110 automatic movement displaying hours, minutes, seconds, and date. The ceramic, sintered from zirconium oxide, reaches approximately 1,200 Vickers hardness and resists daily scratches and temperature variations. The integrated resin dampens vibrations, resulting in notably lighter weight than steel equivalents. Lug width measures 20mm with integrated geometry requiring precise dimensional compatibility in replacement straps.
