In 1982. Seiko released the divers’ version into the cutting edge, “Duo” range. The Duo combined analogue style and practicality with the multi functionality of digital technology.
This divers’, rated to 150meters was the first to feature chronograph and alarm. It was also very distinctive with a large black shroud around the case. No other divers’ looked like it or functioned like it.
Arnold Schwarzenegger wore this model in several movies of the mid 80’s and so, the nickname, “Arnie” for this watch seems natural. And Arnie said “I’ll be back”. True to his word, the Seiko “Arnie” is back!

The original featured the cutting edge movement, the H558 and here, in my collection, I have a near mint example from 1984.
Apart from the oversized push buttons and the whole watch being beefier, the new release “Arnie” looks almost identical.

Seiko have done a fabulous job at re creating classic designs, the re invention of the “Turtle” design of the 70’s divers’ is an example and now, with this, the “Arnie”, they have excelled in reproducing one of their most distinctive and iconic creations using modern technology while staying faithful to the original style.
