Experience the groundbreaking innovation and avant-garde industrial design of 1970s Japanese watchmaking with this authentic vintage Seiko Hexagon 6139 7080 automatic chronograph. Introduced during the golden age of mechanical timing, Seiko’s 6139 family revolutionized horology as the world’s first mass-produced automatic chronograph movement. Housed in a striking geometric hexagonal case with an electric blue dial, this Reference 6139-7080 stands out as one of the most character-rich collector chronographs of the mid-1970s.

Sunburst Petrol Blue Dial with Contrasting Accents

The focal point of this timepiece is its multi-tone blue dial, which shifts dynamically from dark petrol to royal blue depending on lighting conditions. The dial features a light cyan/blue inner 60-second chapter ring, applied polished steel baton indices with luminous inserts, and an isolated 30-minute chronograph counter at 6 o’clock with concentric snailing. An eye-catching orange central sweep chronograph hand injects vibrant motorsport energy, while a framed dual-language day-date aperture at 3 o’clock ensures complete everyday functionality.

Sculptural 40mm Angular Hexagonal Stainless Steel Case

Setting this reference apart from conventional round chronographs is its sculpted vintage 1970s Seiko sports chronograph architecture. Measuring 40mm wide by 42mm lug-to-lug, the angular hexagonal case is engineered from solid 316L stainless steel. It showcases fine radial brushed grain on the upper surfaces framed by mirror-polished beveled edges. The recessed crown at 3:45 is tucked flush against the case body to prevent wrist interference, while dual tactile pump pushers at 2 and 4 o’clock control the chronograph mechanism with mechanical precision.

Legendary In-House Column Wheel Calibre 6139

Beneath the screw-down stainless steel caseback beats the historic column wheel vertical clutch vintage Seiko movement—Calibre 6139. Renowned worldwide for introducing the column wheel and vertical clutch architecture to automatic chronographs, this 17-jewel movement eliminates the initial stutter of the chronograph second hand upon start-up. Operating at 21,600 vibrations per hour, it features Seiko’s patented “Magic Lever” bidirectional winding system and an intuitive push-crown mechanism that allows you to quickset both the day and date smoothly.

An Avant-Garde 1970s Collector’s Piece

Fitted to a multi-link stainless steel bracelet that complements the geometric case lines, this Seiko 6139 7080 stainless steel timepiece is ready for immediate rotation.
