This configuration pairs stainless steel with 18k yellow gold in a smooth-bezel execution that reads more understated than its fluted counterparts. A black dial absorbs light while ten diamond hour markers introduce discrete brilliance, each set in a yellow gold surround that echoes the bezel's warm tone. The Cyclops date aperture at three o'clock maintains the Datejust's functional signature.\u003c\/p\u003e\n\u003cp\u003eInside, the Caliber 2135 automatic movement delivers 42 hours of power reserve through a bidirectional rotor, keeping time with the reliability that defined Rolex's mid-size offerings through the 1980s and 1990s. The three-link Oyster bracelet continues the two-tone construction with brushed steel outer links and polished gold center links, secured by a folding clasp that sits flat against the wrist. Screw-down crown and solid case back ensure 100 meters of water resistance, making this dress-leaning reference practical enough for daily rotation.\u003c\/p\u003e\n\u003cp\u003eThis piece presents in excellent condition and comes with its original box.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"50%\"\u003e\u003cstrong\u003e\u003cbig\u003eMovement\u003c\/big\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eAutomatic, self-winding\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibre\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e2135\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Reserve (h)\u003c\/td\u003e\n\u003ctd\u003e42\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNo. of Jewels\u003c\/td\u003e\n\u003ctd\u003e29\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e28,800 vph (4 Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctions\u003c\/td\u003e\n\u003ctd\u003eHours, minutes, seconds, quickset date\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"50%\"\u003e\u003cstrong\u003e\u003cbig\u003eCase\u003c\/big\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Material\u003c\/td\u003e\n\u003ctd\u003eStainless steel and 18k yellow gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Diameter\u003c\/td\u003e\n\u003ctd\u003e31 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Resistance\u003c\/td\u003e\n\u003ctd\u003e100 m \/ 330 feet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBezel\u003c\/td\u003e\n\u003ctd\u003eSmooth, 18k yellow gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrystal\u003c\/td\u003e\n\u003ctd\u003eSapphire with Cyclops date lens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrown\u003c\/td\u003e\n\u003ctd\u003eScrew-down\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Back\u003c\/td\u003e\n\u003ctd\u003eSolid, screw-down\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Colour\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Indicators\u003c\/td\u003e\n\u003ctd\u003eDiamond hour markers in gold surrounds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"50%\"\u003e\u003cstrong\u003e\u003cbig\u003eBracelet\u003c\/big\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBracelet Material\u003c\/td\u003e\n\u003ctd\u003eStainless steel and 18k yellow gold, three-link Oyster\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClasp\u003c\/td\u003e\n\u003ctd\u003eFolding clasp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClasp Material\u003c\/td\u003e\n\u003ctd\u003eStainless steel and 18k yellow gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003ch4\u003eInclusions\u003c\/h4\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eBox only, excellent condition\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Rolex","offers":[{"title":"Default Title","offer_id":67604194492712,"sku":"68243","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2517\/4164\/files\/Screenshot2026-09-26at1.05.55pm.png?v=1790391962","url":"https:\/\/swissemporium.com.au\/products\/rolex-datejust-31-reference-68243-two-tone-black-diamond-dial-smooth-bezel","provider":"Swiss Emporium","version":"1.0","type":"link"}
