As important as any watch can be too the efficacy of a brand, the 6309-7040/9 is a perfect delivery of intention. It's as rugged and hard wearing as it is aesthetically satisfying. Even as the first "Turtles" released in 1976 turned 43 this year, one thing is certain... they don't get old. This early example from April of 1977 is no exception. Unpolished, and completely original aside from a replacement crystal and strap, it's an opportunity to add an icon to your roster. As most collectors prefer, it carries the signature “S” logo just above the 6 o'clock marker on the matte black dial signifying that it was completely assembled at the Suwa factory in Japan. The luminous plots are the original, and have developed a creamy patina, though some darkening and spotting is visible as well. The hands have mostly retained their polished finish, but some oxidation can be seen. The luminous in the hands has aged into a dark but even khaki that adds a great level of character. The bezel rotates with a firm click in either direction, and considering it’s age, the insert bears only moderate wear. The crown and case back screw down tightly, and the 6309 they protect is a workhorse movement ready to provide many more years of service. Post service, it has a great reserve and is keeping near perfect time. We’ve paired it with a heavy Army Green NATO that perfectly balances the black dial and bezel, and is comfortable for everyday wear. A true Seiko icon, and still their top selling diver to date, it’s a must have for any collector
