Ref: 6139-7100 | Circa 1977 | Automatic Chronograph | £399
Every watch tells a story. And this one is… a bold slice of 1970s chronograph history.
The Seiko “Helmet” is one of the brand’s most distinctive vintage designs, instantly recognisable thanks to its unique case shape and integrated chronograph layout. Produced during the golden era of automatic chronographs, the 6139 movement sits right at the heart of Seiko’s innovation in the 1970s.
This 1977 example carries all the charm you’d expect from a vintage piece, with its brushed steel case, utilitarian dial layout, and that unmistakable presence on the wrist. It’s a watch that feels purposeful, mechanical, and full of character.
Fitted on an aftermarket leather strap, it offers a more wearable, everyday take on what is otherwise a proper collector’s piece.
