Needing little in the way of an introduction, Seiko’s H558-5000, or “Arnie” as it’s more commonly referred to, is one of the few pieces that have me throw my “no quartz” rule right out of the shop window. 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 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 destroy the movement. But, for those willing to be patient, a good example is certainly worth waiting for. This example from May of ‘85 is textbook. It’s completely original aside from a replacement crystal (mineral) and strap. The shroud is the original, and is held in place by the original screws and collars. It is free of cracks or chipping and only has a few minor scratches. The bezel rotates freely in either direction, and the insert has light, but even wear. The dial and depth meter are near perfect and free of blemishes or fading. The original luminous plots have only a faint patina, and the hands have retained their original polished finish. The luminous material in the hands is a perfect match to the dial, though there is some light spotting that has developed along the edges. The reverse “lollipop” second had is perfect, showing no chipping or paint loss. The digital display is crisp, and all functions are working correctly including the incandescent bulb and chiming alarm. The case is unpolished and shows only minimal wear as it’s been protected by the shroud. The crown and case back are both screw down. As setting this watch is  somewhat involved, we’ve added a link too the instructions below. It comes paired with Uncle Seiko’s newly released GL831 reproduction strap that adds a perfect finish, and closely resembles the original. 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, this one is sure to earn a regular spot in any rotation.
