💡 Collectability
The Seiko 6139 series changed watchmaking forever — it was among the very first automatic chronographs, released alongside Zenith and Heuer in 1969.
This 6139-6012 “Baby Pogue” is a lesser-seen variant, often mistaken for its sibling 6139-6002, but with a distinct case profile and cleaner dial design.
Original examples with their factory bracelet are increasingly rare and highly sought-after.
