Omega Seamaster Cosmic 2000 Ref.166.0128 Cal.1012 38.0mm 1971

This well-preserved Omega Seamaster Cosmic 2000 Ref.166.0128 is housed in a 38.0mm stainless steel case with a striking silver satin dial, complemented by clean baton hands and applied indices with warm tritium patina. A unique vintage piece that perfectly captures the innovative spirit of Omega during the 1970s.
