One of the best Seamasters we have had for a while! This no date, silver dialed steel watch is a real jewel. The gold applied Omega logo, pointed baton hour markers and the gold hands sparkle. It really looks like it came from the original dealer! The serial number (21460144) on the manual caliber 600 movement dates it to ca 1964. The slim case (only 9,8 mm thick) has dimensions; diameter 33,5 mm, lug tip to lug tip 40,3 mm and will fit both a slender and a stronger wrist. The movement is in top shape, having been recently fully serviced by our Omega certified watchmaker.
