Since 2005, Hublot's Big Bang model has been the watchmaker's platform for innovative movements and complications as well as state-of-the-art materials such as carbon, titanium, ceramic and synthetic sapphire.

Possessing greater brilliance than sapphire, SAXEM was first developed in the field of satellite technology. Hublot has adopted this ultra-resistant alloy in haute horlogerie, initially in an emerald colour for the Big Bang MP-11 launched in 2019 followed by the verdant Spirit of Big Bang model.
