Once again displaying prowess to the fusion of materials and traditional aesthetics, Hublot launched the Big Bang Aero Bang Tungsten in 2009, being the first in the lineage of the Aero Bang model to incorporate one of the most prestigious and robust materials, Tungsten. Discovered by Carl Wilhelm Scheele in 1781, Tungsten is among one of the rarest metals with a hardness 10 times harder than 18K gold, 5 times harder than steel and 4 times harder than titanium measuring between 8-9 on the Mohs scale of hardness.
