The H601 had a long production run and wide reference spread — references like H601-0029, H601-5348, H601-5461, H601-7030, and H601-802A turn up dated anywhere from 1987 into the early ’90s, with at least one dial variant popularized by its association with Schwarzenegger in Predator (riding on the H558’s cultural cachet even though the H601 itself wasn’t the screen-worn piece).
