Hublot Big Bang All Black Carbon

Completely black, completely matt, completely true to Hublot’s trademark concept of “invisible visibility”, this is the first time that a Big Bang has been made entirely from carbon fibre. The construction of its 44 mm case and dial called for very special expertise in the working of the 100% carbon fibre.

Its completely black HUB4100 movement (black PVD, ruthenium and black gold coating) extends the All Black Carbon concept to the whole piece, for a light, intriguing, almost stealthy look. This is all rounded off by a black alligator gummy strap, ultra-flexible and comfortable by virtue of its black natural rubber inner surface, bringing a refined touch to this already cult model.
