Update on 9/3/22 - I fully serviced this watch. It has all new seals and a brand new NOS rare original crystal right out of the packet. Runs like a dream.

Original listing:

This Seiko H558-5010 from November 1984 is the Fieldmaster version of the Arnie. This watch came first and the Arnie was designed second. The design of this watch was created by the same man and team that designed the 6105-8110 and the 6309 divers. It’s completely original and has a beautiful blasted finish. This was the first watch to have the “ashtray” bezel. These originally came on a black leather strap with notched corners. The sweep orange is only slightly faded. Insert is excellent, including the unfaded orange around the pip and the cardinal directions.

HEAD ONLY! STRAP NOT INCLUDED!
