Vintage Seiko ARC Ultra Slim Gold Dial Dress Watch - 1221-5740 - 1985

A sharp and highly underrated example of a mid-1980s Seiko ARC, one of Seiko’s lesser-known Japanese domestic lines focused on ultra-slim design and refined wearable elegance. ARC models were never widely exported, which makes clean survivors like this increasingly difficult to find today.

This piece features a striking gold brushed dial with minimalist markers and a bold rectangular case design that leans heavily into classic 1980s Japanese geometry. The result is a watch that feels both architectural and elegant — a proper dress watch with personality, rather than something generic.

Inside is Seiko’s calibre 1221, part of Seiko’s push into ultra-thin quartz movements during the 1980s. These movements were engineered for slim profiles without sacrificing accuracy or dependability.

The watch presents beautifully, with a clean crystal, crisp dial, and sharp case lines. It also retains its original Seiko ARC bracelet, which elevates both the look and collectability. Finding these with the correct bracelet in this condition is getting harder and harder each year.

An excellent choice if you’re after a genuine Japanese domestic market Seiko with strong vintage character, great design, and the kind of under-the-radar appeal collectors are increasingly hunting for.
