WHAT WE LOVE:
Released in 1969, this reference was part of the legendary Speedtimer family that helped launch one of the world’s first automatic chronograph movements. It was developed entirely in-house, from movement to case to dial, at a time when Seiko was rapidly asserting itself on the global stage.
Early examples like this one are especially sought-after for their “proof” dials, single-line text under the Seiko logo, and waterproof casebacks, which mark them as some of the very first production units. The dial, inner rotating bezel, and distinctive cushion case give it a bold, sporty presence that still feels modern today. Whether you’re a Seiko collector or a vintage chronograph enthusiast, this is a reference that deserves a place in any serious collection.
WHAT’S INSIDE:
Powering the watch is Seiko’s historic Caliber 6139, an automatic column-wheel chronograph with a vertical clutch — technologies that wouldn’t become mainstream in Swiss watchmaking until decades later. It features a 30-minute chronograph counter, day/date complication, and can be manually wound. For 1969, this was cutting-edge technology and remains a testament to Seiko’s innovation.
