As production of the 6309 ended in 1988, Seiko introduced it’s next generation of 150m sport divers by way of the 7002. It is the direct predecessor to the recently discontinued SKX line, and owning one can feel like the perfect blend of past and present. This example from July of ‘91 is outstanding and shares many similarities with the final 6309 “Slim Turtle” models. The case is unpolished and shows minimal wear throughout. It’s original finishes and bevels are still quite crisp and clearly visible. The bezel rotates smoothly in either direction, and wear to the insert is scattered and light. The matte black dial is near perfect, and features rectangular markers at every hour except the 12. There, two opposing triangles meet at a point just above the silver printed SEIKO logo. The luminous material, in this case promethium, has developed a metallic silver patina that is distinct to these models. The hands are recognizable in design, sharing the same characteristics as previous models, and the luminous within is a clean cream white. The oversized crown is positioned at four o’clock between two large guards, and along with the case back, screws down tightly with ample threading. It’s completely original aside from a replacement crystal. The date can be quickset via the crown, and post service, this one is keeping near perfect time. We’ve paired it with a supple “tropic sport” style strap that feels and looks great on the wrist. With so many examples fitted with modified and aftermarket parts, opportunities to own an original example in this condition are becoming increasingly rare. Don’t wait on this one.
