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 41 this year, one thing is certain... they don't get old. This example from September of ‘77 is no exception. Completely original aside from a replacement crystal, it's an opportunity to add an icon to your roster. As most collectors prefer, it carries the signature Suwa 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. Just one year later, Case production was moved to Hong Kong. The luminous material has begun to develop a creamy patina, and the unpolished case still bears the original factory finishes. The bezel and insert show almost no wear, and it rotates in either direction with a satisfying “click.” 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. A rich slate green, heavy two-piece NATO with stainless hardware provides a rugged but refined finish for one of our favorite Seiko tool watches.
