This Japan Domestic Market (JDM) exclusive was equipped with the revolutionary Seiko Caliber 6139 - one of the world’s first automatic chronograph movements, introduced in 1969. Unlike its more commonly seen cousins (like the 6139-600X \"Pogue\"), the 7020 reference stood out with its sleeker, more minimalistic case design and distinctive dial layout. The \"Speed-Timer\" branding, reserved only for JDM models, underscored Seiko’s ambition to compete with Swiss chronographs in both performance and style. The version with a black dial and champagne subdial is particularly sought after among collectors for its rarity and dynamic aesthetic.\u003c\/p\u003e\n\u003cp style=\"margin: 0in; font-family: Calibri; font-size: 11.0pt;\"\u003e \u003c\/p\u003e\n\u003cp style=\"margin: 0in; font-family: Calibri; font-size: 12.0pt;\"\u003e\u003cspan style=\"font-weight: bold;\"\u003eSpecifications:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul type=\"disc\" style=\"direction: ltr; unicode-bidi: embed; margin-top: 0in; margin-bottom: 0in;\"\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eReference:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e 6139-7020\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eSerial Number:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e 140XXX\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eProduction Date:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e April 1971\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eMovement:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e Seiko 6139 automatic chronograph\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eFunctions:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e Chronograph, inner rotating bezel, day-date with English\/Kanji language\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eCase Material:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e Stainless steel\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eCase Diameter:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e 41 mm\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eLug Width:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e 19 mm\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eDial:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e Matte black with contrasting champagne subdial\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eCrystal:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e New, scratch-free acrylic\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli style=\"margin-top: 0; margin-bottom: 0; vertical-align: middle;\"\u003e\n\u003cspan style=\"font-weight: bold; font-family: Calibri; font-size: 11.0pt;\"\u003eBracelet:\u003c\/span\u003e\u003cspan style=\"font-family: Calibri; font-size: 11.0pt;\"\u003e Original Seiko bracelet, fits up to approx. 18.5 cm wrist\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"margin: 0in; margin-left: .375in; font-family: Calibri; font-size: 11.0pt;\"\u003e \u003c\/p\u003e\n\u003cp style=\"margin: 0in; font-family: Calibri; font-size: 12.0pt;\"\u003e\u003cspan style=\"font-weight: bold;\"\u003eCondition:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0in; font-family: Calibri; font-size: 11.0pt;\"\u003eThis vintage Seiko Speed-Timer is in beautiful, fully functional condition. The 6139 movement has been recently serviced and fitted with new gaskets, ensuring reliable performance. The chronograph starts, stops, and resets perfectly. The original dial and hands are exceptionally clean, maintaining strong detail. The case and bracelet show light signs of wear consistent with age but remain sharp and unpolished. The inner rotating bezel operates smoothly, and the day-date wheel features both English and Kanji options. The crystal is brand new and blemish-free.\u003c\/p\u003e","brand":"SpecialTimer","offers":[{"title":"Default Title","offer_id":52740859035978,"sku":null,"price":163400.0,"currency_code":"HUF","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/0694\/7658\/files\/specialtimer_speedtimerchrono_6139-7020_1.jpg?v=1757250281","url":"https:\/\/specialtimer.com\/en-hu\/products\/seiko-5-sports-speed-timer-6139-7020-1971","provider":"SpecialTimer","version":"1.0","type":"link"}
