The 6-digit Mid-size Datejust utilizes the latest in Rolex technology to offer a watch that you will be proud to display on your wrist. A stunning companion for any event, the reference 178240 that is offered here today features a 904L stainless steel Jubilee bracelet with a hidden Crownclasp. A coordinating mid-size 31mm Oyster case is topped with a smooth bezel and a black dial adorned with luminous baton hour markers in white gold surrounds, matching sweeping hands with lume plots, a white "Railroad" chapter ring, and a date aperture at the 3-hour marker. A scratch-resistant sapphire crystal and a Twinlock screw-down crown offer reliable protection for the dial and automatic, 31 jewel movement within the case. The case itself employs an innovative process of screwing the case back, bezel, and Twinlock screw-down crown to the Monobloc middle case to provide waterproof protection up to 330 feet. Perfect for everyday wear!
