Hublot Big Bang Earl Gray

Posted on by

A Big Bang in a soft but intense matt gray finish, enhanced by the diamonds surrounding the dial. Novelty comes in the form of the subtle, gray alligator strap, made supple by the rubber stitched on the inside. With a silvered elegance that contrasts the matt with the brilliant, the Big Bang Earl Gray can also be worn with an articulated steel strap, whose side is covered with gray composite resin.
The gray shades of the steel, the tantalum-coloured dial, the leather and the resin are in harmony, evoking the fusion of materials, a key concept for Hublot.
