Seiko 5 Automatic Vintage “Tank” Mid Size Watch

This good condition Seiko 5 Automatic Day Date Watch has a tank-style, elongated hexagon shaped case in stainless steel. This unisex watch has a case-width (3H to 9H) of 30.45mm and a length of 32.40mm.

The watch has a rectangular face with a round dial featuring gold-toned hands and indexes. This model has a flat glass and domed, screw-in case-back.

It houses the Seiko Calibre 2906, a vintage, high-beat mechanical automatic movement introduced in the late 1970s. Built primarily for women's and mid-size watches—including vintage Seiko 5 models—it features 17 jewels, day-date function, and a smooth 28,800 vibrations per hour frequency. 

Both the day and date are quick-set, adjustable by the crown at 3H. The watch is paired with an original Seiko steel bracelet featuring a folding clasp.

The condition of the watch is good and ready to wear. Both the case and bracelet are unpolished and they show minor signs of age and wear.
