We all know: Omega was one of the most innovative and brave watch companies in the 1970s and 1980s -- not many other brands that come close to variety of models and technologies.

The most overlooked and interesting movements was for sure their 720Hz MegaSonic and their ceramic metallic-alloy Cermet is the material one of their most interesting watches is made of: Omega Seamaster Black Tulip / Cermet (ref396.0945). Once one of their highest priced pieces it shines as bright today as it did when it was originally sold approx 40 years ago: the 2'000 Vickers hardness beats any other watch case material and is just topped by the non-plus-ultra-hardness of a diamond.
