As production of the 6309 ended in 1988, Seiko introduced its next generation of 150m Sport Divers by way of the 7002. It is the direct predecessor to the recently discontinued SKX, and owning one can feel like the perfect blend of old and new. This inaugural example from December of ‘88 represents the first generation of the 7002 and shares many similarities with the final 6309 production models. The case is unpolished, and shows only minimal wear. The original finishes and bevels are still sharp, and the bezel insert is practically flawless. The dial is perfect. It’s matte black with rectangular markers at every hour except the 12. There, two opposing triangles meet at a point just above the silver SEIKO logo. The luminous material, in this case promethium, has developed a silvery green patina that is distinct to these models. The hands are recognizable in design, looking mostly like those of previous models. There is no degradation or discoloration in the luminous, and the original polished finish is free of any haze or oxidation. The oversized crown is positioned at four o’clock between to large guards, and along with the case back, screws down tightly with ample threading. It’s completely original aside from a replacement mineral crystal, and a stunning example of Seiko’s fourth generation pro diver. Post service it’s keeping near perfect time, and the date can be quickset via the crown in the second position. We’ve paired it with a replacement Z-22 flat vent strap for a fit and finish very close to the original that feels and looks great on the wrist. With so many examples fitted with inferior and aftermarket parts, opportunities to own an original example in this condition are becoming increasingly rare. Don’t wait on this one.
