The bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date window completes the case.\u003c\/p\u003e\u003cp\u003eThe dark grey dial is itself set with diamonds, with the large VI marker further enhanced by a cluster of 11 diamonds. Roman numerals mark the hours, and the instantaneous date display with rapid setting adds everyday practicality. The three-piece solid-link Oyster bracelet, rendered in Yellow Rolesor, fastens via a folding Oysterclasp with an Easylink 5mm comfort extension link.\u003c\/p\u003e\u003cp\u003ePower comes from the Calibre 2236, a perpetual mechanical self-winding movement manufactured by Rolex. A Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers underpin its performance, while a precision rating of -2\/+2 seconds per day after casing reflects its Superlative Chronometer status — certified by both COSC and Rolex. The movement delivers a power reserve of approximately 55 hours via bidirectional winding through a Perpetual rotor.\u003c\/p\u003e","brand":"It's That Time","offers":[{"title":"Default Title","offer_id":49919892914405,"sku":null,"price":27351.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/5600\/7653\/files\/rolex-datejust-278383rbr-0017.jpg?v=1782916176","url":"https:\/\/itsthattimenyc.com\/products\/rolex-datejust-278383rbr-0017-31mm-dark-grey-dial-oyster-bracelet","provider":"It's That Time ","version":"1.0","type":"link"}
