The black Technic dial with the red Omega logo
This is one of the favourites of the Seamaster 600 in my collection. The Technic dial stands out fram the rest with the printed/painted indexes, the red logo and crosshair – a meaner look. This watch comes with a movement serial number 220xxxxx dating it from 1965. The case reference being 135.011 and case material is pure stainless steel. The movement is caliber 601 and this dial style/version is also available with case reference 136.011 with caliber 611 and date. The black faced version of the Technic uses tritium painted indexes and are harder to find in great condition compared to the whtite dialed version.
