Seems to be a very rare catalog page, found on this site. I don't know if the Kanji text shows up on your computer, but if it does, can anyone translate some of this? Email me if you know. I'd love to know what they say about the Red Mark, the Special Case, the Special Hands, and mostly the Special Band! Seiko was obviously very proud of this watch, and spared no description of its various features. Note that the SUS Concept seems to stand for 'simple and strong.'
