This timepiece is a magnificent artifact from June 1983, as confirmed by the serial number 365563. The reference 7A28-6000 is defined by its radical asymmetrical black-coated stainless steel case and its striking red accents, a design specifically engineered by Giugiaro for motorcycle riders to easily operate the pushers while wearing gloves. It is powered by the groundbreaking Caliber 7A28, a mechanical-quartz hybrid movement featuring 15 jewels and a completely metal gear train, marking it as the world’s first analog quartz chronograph movement ever produced.

The architecture is quintessentially retro-futuristic, utilizing a unique vertical pusher housing that creates an unmistakable profile on the wrist. The dial is a work of high-intensity functional art, featuring three sub-registers for split-second timing and a rotating bezel with red tachymeter-style markings. Flipping the watch over reveals the crisp caseback engraving and the serial number 365563, definitively confirming its heritage from the early production run of this iconic series. This is an essential acquisition for an elite collector who appreciates cinematic history, the mechanical soul of a 15-jewel quartz heart, and the bold, asymmetrical presence of the "Bishop" Seiko.
