Get your hands on this serviced January 1968 Seiko 5 DX 5139-7010 with 27-jewel calibre 5139A, silver sunburst dial, Kanji day display, fluted bezel and 3-month guarantee. Model History: Introduced during the late 1960s, the Seiko 5 DX represented a more refined “Deluxe” interpretation of the practical Seiko 5 concept. DX models were distinguished by higher jewel-count movements and more elaborate design details while retaining the everyday functionality associated with the collection. Manufactured in January 1968, this example combines a silver sunburst dial with a distinctive fluted bezel. It is powered by the comparatively uncommon 27-jewel calibre 5139A, part of Seiko’s technically advanced 51-series movement family.
