Featuring a wide variety of case and dial designs, the 1970s were very much the golden age of Seiko sports watches. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eThis particular automatic Seiko chronograph is a classic ‘Jumbo’ Reference 6138-3000 from circa the early 1970s. Housed in a 42mm stainless steel cushion case with a mineral crystal, barrel pushers, and a polished faceted bezel, it features a matte black Tritium dial with a raised outer chapter ring and a dual-register chronograph, a matching handset, and a day-date display. Powered by the famed Caliber 6138 movement, it comes paired to a cool, stainless steel multi-link bracelet with a signed blade clasp.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eTo misquote the Bard, ‘a watch by any other name would be many times as expensive.’ So whether you’re just getting into chronographs or you’re a Seiko die-hard, you owe it to yourself to give this Jumbo a whirl.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eTry it on today!\u003c\/span\u003e\u003c\/p\u003e","brand":"Seiko","offers":[{"title":"Default Title","offer_id":39845542985815,"sku":"40991058","price":890.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/1255\/products\/AS07150_40991058_SEIKO_JUMBO6138-3000_6138-3000-6.jpg?v=1659039811","url":"https:\/\/www.analogshift.com\/products\/seiko-jumbo-automatic-chronograph-as07150","provider":"Analog:Shift","version":"1.0","type":"link"}
