About the Datejust family
The Datejust appeared in 1945 as the first self-winding wristwatch to show the date in a window, together with the Jubilee bracelet designed for it. The Cyclops magnifier over the date followed in the 1950s, and the combination of fluted bezel, date window and Jubilee bracelet has stayed the model's signature ever since.
The catalog covers several generations, from caliber 3135 references to the current 3235 models: the Datejust 41, such as refs. 126300, 126331 and 126333, and the Datejust 36, such as refs. 126200, 126233 and 126234. Variants combine steel, Rolesor and gold with smooth or fluted bezels, Oyster or Jubilee bracelets and a very wide choice of dials. For dealers the exact dial, bezel and bracelet combination is what separates otherwise similar watches, so they are always described together.
