Arabic numerals and Geneve added to the model name – could it get any better?
This is the “youngest” of the Seamaster 600 in my collection with a movement serial number 326xxxxx dating from 1970. Applied arabic numerals in a somewhat “military” looking typeface. Case reference being 135.011 and case material is stainless steel. The movement is caliber 601. This dial style/version is also available with case reference 136.011 with caliber 613 and a date function.
