Perhaps it doesn’t qualify as a vintage Seiko just yet, but we’re willing to bet this one’s likely already made the list for many. Only in production for around two years, the 4R15-00D0 has already developed a strong cult following of willing buyers with few options. More commonly referred to as the “Spork,” (a loose rearrangement of its Seiko style number SRP043K), it is much like its namesake, serving as a dual purpose pilot and diver. It was the first Seiko pro diver to house the 4R15 after it’s release in ‘08. Though it foregoes hacking or manual winding, it does offer a redeeming 50 hour power reserve. At 44mm, it’s comparable in size to the 6309 “Turtle,” and the profiles are nearly identical as well. It wears extremely well, and the legibility is unmatched. The dial is matte black with large Arabics at the corners that are separated by well balanced luminous plots between. The hands are massive, and have an undeniable military aesthetic. Framing the dial is a large, deep set chapter with hour and minute hashes, and that gives way to a count up insert that makes the dial and chapter lines feel continuous. This example from October of 2010 is unworn new old stock. The dial is immaculate, as are the hands and chapter. The bezel insert is flawless. The uni-directional bezel has smooth action, and is neatly aligned. The case is, of course, unpolished and the case back is still under the protection of the original blue cling film. The crystal is the original hardlex, and is perfect. Post service, the 4R15 is keeping near perfect time, and the date can be quickset via the crown in the second position. It comes attached to the original Seiko Z-20 curved vent strap and buckle, and hanging from it is the original Seiko hang tag. With demand drastically outpacing supply, the “Spork” is on a trajectory towards “grail” status, and this is as good as it gets.
