I have yours's sibling, the 009, love it! I concur with you, I think old SKXs are the quintessential Seikos. It's what comes up in my head immediately when I think 'Seiko' followed by an orange monster.
I have a 007 and 009 both purchased from LIW purchase $180 and $190. I’m so glad I resisted the urge to mod and kept it all original in the jingle jangle jubilee that I love.
