Scratch-resistant sapphire crystal with a Cyclops lens over the date protects the dial, and the watch is waterproof to 100 metres \/ 330 feet. The bezel is set with diamonds, adding a layer of brilliance to the white gold case.\u003c\/p\u003e\u003cp\u003eThe bright black dial is appointed with Roman numeral hour markers, offering a striking contrast that draws the eye across the face. The President bracelet in 18kt white gold features semi-circular three-piece links and fastens via a concealed folding Crownclasp, completing a cohesive all-white-gold presentation on the wrist.\u003c\/p\u003e\u003cp\u003ePowering the watch is the Calibre 2236, a perpetual mechanical self-winding movement made by Rolex. It incorporates a Syloxi silicon hairspring with patented geometry, high-performance Paraflex shock absorbers, and bidirectional winding via a Perpetual rotor. The movement delivers a precision of -2\/+2 seconds per day after casing, an approximately 55-hour power reserve, and carries Superlative Chronometer certification — reflecting both COSC testing and Rolex's own post-casing standards.\u003c\/p\u003e","brand":"It's That Time","offers":[{"title":"Default Title","offer_id":49919885902053,"sku":null,"price":46541.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/5600\/7653\/files\/Rolex-278289rbr-0011-black-diamondset-president.jpg?v=1782916106","url":"https:\/\/itsthattimenyc.com\/products\/rolex-datejust-31mm-278289rbr-0011-bright-black-dial-white-gold-president-watch","provider":"It's That Time ","version":"1.0","type":"link"}
