With its rounded square case and deep-set dial, this Seiko 5 is affectionately known among collectors as the “TV Dial” — a nod to its unique screen-like proportions that mirror old-school television sets. Made in Japan in the late 1970s or early 1980s, this particular model combines a brushed metallic black dial with gold-toned accents, offering an elegant contrast that still holds visual weight decades later.

The 6309 movement inside is part of Seiko’s workhorse automatic lineage — known for its robustness and reliability over time. The day-date complication is tucked away neatly at 3 o'clock, while the minimalist branding and subtle chapter ring add to the charm. The watch retains its original folded-link stainless steel bracelet and caseback sticker, making it a rare survivor in mostly untouched condition.

This reference doesn’t just carry vintage Seiko credibility — it’s an expressive piece of 1970s design, often overlooked but increasingly appreciated for its retro appeal and quirky proportions. A proper sleeper in Seiko’s rich design archive.
