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 turn 50 this year, one thing is certain... they never get old. This example from November of ‘77 is no exception, and its early production signifies it was built and cased entirely at Seiko’s Suwa facility in Nagano . The Suwa “S” logo can be seen just above the six o’clock marker, and for many collectors, it’s the first thing to look for when considering an acquisition. The dial is a clean matte black, and the luminous plots have developed a light “sand” patina that is even throughout. The hour and minute hands have mostly retained their original polished finish, though some visible oxidation is present. The bezel rotates with a firm click in either direction, and while the insert shows moderate wear throughout, it is even, and the markings are still clear and legible. The crown and case back screw down tightly, and the 6309A is a near bulletproof workhorse ready to provide many more years of reliable service. Post service, it’s keeping near perfect time, and the day and date can be independently quickset via the crown in the second postion. It’s unpolished and completely original aside from a replacement crystal. Attached is the original Seiko GL-831 flat vent strap that’s almost as sought after as the watch itself. A true Seiko icon, and still their top selling diver to date, it’s a must have for any collector, and in our humble opinion, a perfect “tool” watch.
