Seiko’s H558-5000, or “Arnie” as it’s more commonly referred to, is one of just a few quartz pieces we actively pursue. Introduced in 1982, it was the first ever diver to have an analog and digital display with a chronograph and an alarm. It is a beast of a watch at nearly 46mm including the shroud, and so it seems fitting that it would eventually become synonymous with its biggest fan, Arnold Schwarzenegger. Arnie, with a fairly well documented collection of great watches already, rode out most of the 80’s with his favorite Seiko strapped to his wrist. It even saw significant screen time in the movies “Predator” and “Commando.” Considered by collectors to be a fringe member of the “Tuna” family of Seiko divers, an honest, fully working example can be a bit hard to come by these days as they were often worn hard by those for whom it was designed. The shroud material can become brittle with age, and moisture intrusion or a dead battery left sitting can destroy the movement. But, for those willing to be patient, a great example is certainly worth waiting for. This example from February of ‘85 is just that. The matte black dial is flawless, and the hour markers are a spotless bright white. It’s framed by an equally clean depth meter and minute chapter, and the hour and minute hands have retained their bright polished finish. The digital display is crisp, and all functions are operating correctly, including the alarm, hourly chime, and the incandescent backlight. The crystal is the original hardlex, which shows only a couple of very small blemishes after careful polishing. The bezel rotates with a firm click in either direction, and the insert shows only moderate wear. The shroud is the original, and is secured to the case with the original screws and collars. It is completely intact with no breaks, cracks, or worn corners. The crown and case back screw down tightly, and the case is crisp and unpolished. We’ve paired it with a Seiko Z-22 flat vent strap for a fit and finish very close to the original. As setting this watch is somewhat involved, we’ve added a link to the instruction manual below. All of the electronic components were carefully disassembled and cleaned and the analog portion was cleaned and serviced. A new battery was installed as well. A fantastic example of an historic Seiko diver, it’s sure to become a centerpiece in any collection.
