Seiko 6309-8049 – Vintage 1970s Automatic (Unmodified, Original)
Although we specialise in Seiko mods, this watch is not a mod. This is a genuine, unmodified Seiko 6309-8049 from the 1970s – exactly as it left the factory over 40 years ago.
What makes this piece stand out immediately is its stunning faceted crystal, which catches the light from every angle, paired with a vibrant textured blue dial that is pure vintage Seiko charm. This design is a perfect time capsule of the bold aesthetics Seiko experimented with in the early ’70s.

Collector’s Note
Faceted-crystal Seikos from the early 1970s are becoming increasingly difficult to source in clean, original condition. The play of light across the cut glass, paired with Seiko’s experimental dials of the era, has made them highly collectible among enthusiasts. Many surviving examples are heavily worn or have had their crystals replaced — making an intact original like this a rarer find.
This Seiko is more than just a timepiece – it’s a slice of history. The bold dial pattern, unique faceted crystal, and timeless Japanese craftsmanship make it a standout for collectors and vintage lovers alike.
