Introduced in the mid-2000s, it carries the Caliber 2235, a movement built on the 2000-series architecture with a Parachrom hairspring and Rolex's own Glucydur balance — a combination that delivers COSC chronometer accuracy with meaningful resistance to magnetic fields and temperature variation. The screw-down crown and quick-set date mechanism are standard, but on a 31mm case they feel considered rather than incidental.\u003c\/p\u003e\u003cp\u003eThis example presents on a silver dial with Arabic indices — a configuration that ages better than the busier diamond-set alternatives, keeping the dial legible and the overall read clean. The smooth bezel and smooth bracelet reinforce that restraint; there is nothing here competing with the dial. In certain light, the silver surface shifts between warm and cool in a way that a photograph simply flattens. The Z-serial dating places production around 2007, and the watch presents throughout in very good condition with hardly visible signs of wear across the case, crystal, bracelet, bezel, and caseback.\u003c\/p\u003e\u003cp\u003eOffered in very good condition, watch only.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":55048245444821,"sku":"IT9085","price":6190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/3182\/9461\/files\/Rolex_DJ_scatter1.webp?v=1790262178","url":"https:\/\/iconic-timepieces.com\/products\/rolex-datejust-31-178240-silver-dial-on-smooth-2007","provider":"Iconic Timepieces","version":"1.0","type":"link"}
