The Datejust in its classical proportion. Everything true of the line is true here — the 1945 lineage, the Cyclops, the choice of Jubilee or Oyster — but 36mm is the size the design was drawn around, and the one most collectors mean when they say "a Datejust". Calibre 3235 is the current-generation movement, with the Chronergy escapement and roughly seventy hours of reserve. Water resistant to 100m. What matters on examination: whether the case has been polished, since at 36mm the lug profile is the reference's whole character; bracelet stretch; dial and hand originality as a set; and on the gem-set configurations, that the papers record the stone specification. Confirmed through the desk. Maker: Rolex. Reference: 126234-0017. Available through ELITA's private desk — verification review, discreet handling and storage. Price on request.
