The Datejust 36 is the size the model launched in, and 126233 is the yellow gold and steel version. Setting brilliant-cut diamonds at the hours is the point where this reference stops being an everyday watch and starts being a dress one. Champagne was developed to sit with yellow gold, so the stones read as brightness inside a warm field rather than as contrast against it. It is one of the few gem-set Datejusts still in the current catalog.

A Stainless Steel Oyster case of 36 mm sits under a fluted bezel in Yellow Gold. The champagne dial carries diamonds in gold settings where applied markers would normally be, with no printed indices anywhere on it. A sapphire crystal magnifies the date at three through a Cyclops lens. The Jubilee bracelet runs five-piece links, Stainless Steel at the edges against Yellow Gold centers, closing on a folding Oysterclasp with a comfort extension link.
