Seiko's 6139-6010 stands at the intersection of vintage appeal and versatility. This particular model from September of '69 retains a timeless design, having made history as one of the world's first automatic chronographs.
 
The dial has a matte black finish, adorned with a blocked silver minute track and featuring the iconic "70 Proof" marking that distinguishes it as one of the pioneering pieces in the market. The hour and minute hands are sleek polished batons, ensuring effortless readability at a glance, while the bright red chronograph hands add a vibrant touch of color. The angular chapter, finished in glossy black and embellished with a silver tachymetric scale, strikes a perfect balance, infusing a sporty element into an otherwise casual layout.
 
The case exemplifies the quintessential Seiko style, characterized by well-crafted contours, a wide flat bezel, and the original circular brush finish that remains intact. The 6139A movement that powers the hands has been serviced and exhibits near-perfect timekeeping, while the chronograph functions operate with precision and responsiveness. This watch is complemented by the original triple hinged bracelet, further confirming its authenticity and ticking all the boxes for even the most discerning collectors.
