A gold on steel example in mint condition. Please study the pictures carefully, we really haven’t found a flaw on this one. Surprisingly it does not have the Seamaster logo on the back, but this is not exceptionally rare. The watch has not been opened by us, since it runs to near chronometer standards (mean deviation is less than 5 seconds, beat error 0,3ms and amplitude 240 degrees). We are happy to warrant this for 6 months, even though it has not been serviced by us. The manual movement is probably the 17 jewel caliber 611, with 19800 beats. The case is 34,5mm and we date this watch to ca 1965. It comes with an original gold plated Omega buckle on a new Condor “Crocodile Calf” strap.
