What to say about this amazingly unique watch, the H558 "Arnie?" 


The H558 - like this early 1982 example here, the relatively rare orange dial variant, one of the first - was worn by Arnold Schwarzenegger (who noted it as his "favorite watch") in a string of action movies that set the bar for, well, action, in the 1980s, like “The Predator" (1987), “Raw Deal" (1986), “Commando" (1985), (which still has the highest fatality count in an action move, I mean, if you’re into that manner of thing), "Running Man" (1987), and even, yes, "Twins" (1988).


The H558 was released in 1982, and was the first hybrid dive watch rated to 150 meters.  The Japanese are well known for their extreme adventures around the world, and Seiko wanted to provide a watch whose users could rely on with their lives.


As such, Seiko designed its H558 (and the H601) with a few rugged characteristics – many lifesaving. Here are a few (remember, some of these were when the H558 was new, not necessarily now):

   1. Water resistance to 10 atmospheric-pressure depth;

   2. Shock resistance from 3 feet;

   3. Abrasion resistant Hardlex was used, all the better to stand up to decompression;

   4. Resistance to chemical and gas exposure, such as alcohols and cosmetic oils, and ammonia gas and carbon monoxide;

   5. Bright luminescence allowing readability from 25cm in complete darkness; and,

   6. Engineered to withstand temperatures of -40C to 60C (after all, it was tested on expeditions to the south and north poles, as well as, of course an Everest ascent in 1988).


This Seiko H558 comes with its original rubber strap, generic rubber strap, nylon NATO strap, Pelican travel case, and springbar tool.

1982 Seiko H558-5000 "Arnie," Orange Dial Variant w/Original Strap

  • DIAL: Seldom seen Seiko-signed orange dial in good condition, with vibrant blue font - no fade! - and perfect sugar cube-like granular lume on dial; lume shines quite nicely.


    CASE: Stainless-steel case, with shroud, measures 48.5mm x 47.5mm, with matching stainless-steel caseback.  Quality aftermarket black shroud surrounds a bezel with an excellent bezel insert and lume pip, with little to no wear - its quite unusual to find these in this condition.  Original H558 shroud included.


    CRYSTAL: H558-correct Hardlex crystal, no scratches.


    BAND: New 22mm rubber strap.  This H558 also comes with a black nylon NATO strap, with stainless-steel hardware - it also comes with its original Seiko-signed rubber strap.


    MOVEMENT: Seiko H558 quartz hacking movement, manufactured in April 1982; movement uses a button-cell battery.  All functions– including GMT, alarm, stopwatch – work, including the light.  All LCD segments work well and are clearly legible – LCD contrast is excellent.  Movement has no evidence of previous battery leakage.  The H558 featured an altogether different and more robust quartz movement than its little brother, the H601 "upside down Arnie," which unlike the H558, has its LCD display at the bottom of the dial.


    CROWN: Unsigned screw-down crown.
