The Rolex Datejust 41, reference 126300-0005, is cased in 41 mm Oystersteel, with a white dial and a smooth bezel, on an Oyster bracelet. The Datejust invented the self-winding wristwatch with a date display in 1945 — and it has been in continuous production without interruption since. It was the first watch to display the date in a magnifying cyclops lens. The modern 41mm case in Oystersteel or Rolesor occupies a different register entirely from its origins: a complete daily instrument for serious wear, in any context. Calibre 3235 delivers 70 hours of power reserve, magnetic resistance to 1,600 A/m, and certified precision of −2/+2 seconds per day. The Datejust is not a statement watch. It is a working watch that happens to be timeless. Maker: Rolex. Reference: 126300-0005. Available through ELITA's private desk — verification review, discreet handling and storage. Price on request.
