The Hublot Big Bang Reference 301.PI.500.RX is a luxury 44mm automatic chronograph that showcases Hublot's signature "Art of Fusion" by contrasting an 18k rose gold case with a distinctive, matte salmon-toned (or matte gold) dial. This timepiece pairs a sports-forward aesthetic with precious materials.
