This is a stunning black/grey dialed Omega Seamaster 600 from 1965 with a caliber 611 movement. I find the structure, the black/greyish dial colour and the long indices very appealing – yet hard to catch the beauty on pictures. The caliber 611 movement has a serial number 223xxxxx dating it to 1965. The stainless steel case has reference 136.011 which matches the caliber inside.
