Vintage Seiko 5 — Midnight Blue Dial Watch | Ref. 7009-3131.

Vintage Seiko 5 — Midnight Blue Dial Watch | Ref. 7009-3131.

Deep blue in daylight. Nearly black at night.

This dial changes with the light. By a window, it shows as a rich midnight blue. Indoors, it goes dark and moody. Silver baton markers with cream-toned lume sit around the edge, each with a matching lume dot on the outer track. 
Inside is the Seiko 7009A automatic movement with 17 jewels. It's the steady, reliable engine behind a whole generation of Seiko 5s, and it keeps running for decades when it's properly cared for. This one has been.

One piece. No restock. When it's gone, it's gone.

Condition
Fully serviced and checked on a timegrapher. The dial is clean, and the lume has aged evenly to a warm cream colour. The case and bracelet show light wear that fits the watch's age.

Good to know: The 7009 winds itself as you wear it. It does not hand-wind through the crown. If it stops after sitting unworn, give it a gentle shake and it will start running again.
