Seiko 5 Automatic Moonphase Ref. 6347-5000 | Genta Design | Golden Bezel | 1980s

The Seiko 5 Automatic Moonphase Ref. 6347-5000 is a rare and refined timepiece that showcases Seiko’s horological ingenuity and design innovation. Featuring a midnight blue dial and a golden bezel, this watch exudes elegance and sophistication.

The octagonal case (35mm x 38mm) draws inspiration from Gerald Genta’s iconic designs, giving it a bold, architectural presence. The moonphase complication is subtly integrated, appearing slightly flushed below the dial surface, adding a touch of understated complexity.

Powered by the legendary Seiko 6347 caliber, the only automatic moonphase movement Seiko ever created, this timepiece is a testament to the brand’s ability to rival Swiss luxury standards in technical sophistication and design. Whether you’re a Seiko enthusiast or a collector of rare complications, this Moonphase is a true horological gem.
