Seiko 5 DX Automatic 5139-7040 (1967) – vintage silver sunburst dial, 27 jewels, day-date, stainless steel cushion case, on a replacement stainless steel mesh bracelet. PLEASE NOTE: the dial shows dark, rust-coloured corrosion and flaking along its outer edge from about 6:30 to 8 o'clock, clearly visible in the photos, and the inner ring under the crystal has dark tarnish and pitting on the right side from roughly 1 to 4 o'clock. The bracelet is not original; it is a flat mesh-style stainless steel band with a sliding clasp stamped BEAR / STAINLESS STEEL, with a small rust-coloured spot on its edge near the 6 o'clock end piece and tarnish deposits on the inner clasp plate. The case has many hairline scratches and small dings, most noticeable on the right side and the upper-right bezel edge, and the crystal has light hairline scratches. On this calibre the day is not designed to be quick-set; the date can be set with the crown, but the day advances only by turning the hands through midnight, which is the original design and not a defect. Please check the photos carefully before bidding. Overview A 1967 Seiko 5 DX, the deluxe 27-jewel version of the Seiko 5 line, powered by the Seiko 5139 automatic movement.
