Vintage Seiko 6309-8040 Automatic Day Date Brown Gradient Dial Gold 37mm Watch

About this watch

A 1970s Seiko Automatic with reference 6309-8040, powered by Seiko's own calibre 6309 automatic movement with 17 jewels. The dial is a warm brown gradient, lighter at the centre and darker towards the edge, with a fine pebbled texture. It has applied faceted gold baton markers with white lume stripes, a double marker at 12 and a white lume dot at each hour. Gold baton hands carry white lume inserts and a thin dark seconds hand sweeps the dial. The day-date window at 3 o'clock has a gold frame and shows the day in Spanish (e.g. "SAB"). The cushion-shaped gold-plated case has wide polished flanks, a slim round bezel and a domed crystal, and it comes on a gold-plated link bracelet with a signed SEIKO fold-over clasp.

Brand heritage

Seiko traces its roots to 1881, when Kintaro Hattori opened his watch and clock shop in Tokyo. The calibre 6309 was one of Seiko's workhorse automatic movements from the mid-1970s through the 1980s. It powered dress and everyday day-date models like this one as well as the famous 6309-7040 "Turtle" diver, and it is known for being robust and easy to service.
