The Rolex Submariner Date is designed with a 40mm 18-carat white gold case with oyster architecture that features a monobloc middle case, a sapphire crystal and a screw-down case back winding crown. The ceramic bezel rotates unidirectionally and features numerals and raised graduations coated in platinum. The rich blue dial features luminescent hour markers and hands, which makes it legible in even the dimmest lights. The watch comes on a white gold oyster bracelet with a fold-over clasp.Reference Number116619LBModelSubmariner DateMovementAutomaticCase MaterialWhite GoldBracelet MaterialWhite GoldDialBlueCase Diameter40mmYearConditionBox & PapersOriginal box, original papers
