Seiko’s H558-5000, or “Arnie” as it’s more commonly referred to, was the first diver’s watch to have an analog and digital display with a chronograph and an alarm. Introduced in 1982, 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 it’s 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 is plastic and can become brittle with age, and moisture intrusion or a dead battery left sitting can all but destroy the movement. However, for those willing to be patient, a great example is certainly worth waiting for. This early example from March of ‘83 is just that. The dial is near perfect in matte black and the hour markers sport a subtle patina. 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 bezel rotates with a firm click in either direction, and with very little wear, the insert markings are clear and legible. The original shroud is secured to the case with the original screws and collars, and I carefully reinforced the few very small cracks with epoxy resin to help prevent splitting. The crown and case back screw down tightly, and the case is crisp and unpolished. It’s completely original including the original “Hardlex” crystal that shows only minor wear. We’ve paired it with a reproduction Seiko Z-22 flat vent strap for a fit and finish very close to the original. As setting this watch is somewhat involved, I’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 has been installed as well. A beautiful example of an historic Seiko diver, it’s sure to become a fast favorite in any rotation.
