Offering a refreshing departure from Seiko's typically sport-oriented styles found in the 6139 series, the 8002 model showcases a remarkable throwback design that captures the essence of what modern manufacturers strive to achieve.
 
Moreover, it belongs to the rarer "Speed Timer" variation, exclusively obtainable within the Japanese domestic market.
 
Manufactured in May of 1972, it boasts an enticing tonneau-shaped case with delightful colors, elegant contours, and a significant historical movement. The dial, reminiscent of minty freshness, showcases a charming linen purple hue surrounded by a deep orange 1/5 second track that harmoniously connects with the chronograph hands.
 
The sub-register provides a striking contrast, featuring an electric blue five-minute countdown and a fifteen-minute divider. Resting atop the unpolished case is a well-proportioned inset bezel finished with a glossy black inlay.
 
Adding a touch of balance, the Speed Timer logo is positioned opposite the framed day/date window, which offers readings in both Kanji and English. As an early variant, it is equipped with Seiko's initial iteration of its premier automatic chronograph movement, the 6139A. This remarkable caliber incorporates a column wheel design with a vertical clutch, exemplifying its exceptional performance.
 
The chronograph functions operate with impressive speed and responsiveness, while the timekeeping remains remarkably accurate, deviating by just a few seconds per day.
