{"product_id":"rolex-datejust-ref-1601-sigma-dial","title":"Rolex DateJust Ref 1601 Sigma Dial","description":"\u003cdiv\u003eBy the early 1970s, gold prices were climbing fast and Rolex wanted a way to reassure buyers that what looked like gold on the dial really was gold. Their answer was the sigma dial — small Greek σ characters flanking the \"T Swiss T\" at six o'clock, quietly certifying that the hour markers were solid gold rather than gold-plated brass. It's the sort of detail only collectors look for, and exactly the sort of thing that makes a Datejust from this window worth chasing.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eThis Reference 1601 sits squarely in that moment. Introduced in 1959 and produced into the late 1970s, the 1601 is the canonical Datejust of its era — 36mm, fluted 18K white gold bezel against a stainless steel Oyster case, on a Jubilee bracelet that has carried it through more than five decades and still wears with confidence.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eBeneath the surface beats the Rolex Caliber 1570 — the movement that defined Rolex's mid-century engineering. Twenty-six jewels, 19,800 beats per hour, a smooth automatic winding rotor, no hacking, no quickset date. It's the rhythm of a different generation, and after sixty years of running it still does exactly what it was built to do.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb\u003eDial\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cul\u003e\n\u003cli\u003eOriginal sigma dial — σ σ flanking T Swiss T at six o'clock, certifying solid gold hour markers and hands\u003c\/li\u003e\n\u003cli\u003e[Dial color] aged warmly and evenly\u003c\/li\u003e\n\u003cli\u003eOriginal hands and crown\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb\u003eBracelet \u0026amp; Clasp\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cul\u003e\n\u003cli\u003eOriginal Rolex stainless steel Jubilee bracelet\u003c\/li\u003e\n\u003cli\u003eStretch consistent with age\u003c\/li\u003e\n\u003cli\u003eOriginal Rolex clasp\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb\u003eCase\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cul\u003e\n\u003cli\u003eStainless steel Oyster case with 18K white gold fluted bezel\u003c\/li\u003e\n\u003cli\u003eAppears unpolished, strong proportions and sharp edges\u003c\/li\u003e\n\u003cli\u003e36 mm (without crown) \/ 20 mm lug width\u003c\/li\u003e\n\u003cli\u003eReference 1601\u003c\/li\u003e\n\u003cli\u003e1972\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb\u003eMovement\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cul\u003e\n\u003cli\u003eRolex Automatic Caliber 1570\u003c\/li\u003e\n\u003cli\u003e26 jewels, 19,800 A\/h, non-quickset date, non-hacking\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cb\u003eCondition Notes\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003eVery nice vintage condition \u003c\/div\u003e","brand":"Rolex","offers":[{"title":"Default Title","offer_id":44047710486593,"sku":"w_mq78yqqh_oe2n","price":5500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0701\/2122\/6305\/files\/IMG_4326-SqypVuZMsuoFEvEbSBrYfkkYQA3XuX.jpg?v=1781315163","url":"https:\/\/goodtimevintage.net\/products\/rolex-datejust-ref-1601-sigma-dial","provider":"Good Time Vintage","version":"1.0","type":"link"}
