The first Rolex model equipped with a quartz movement was the reference 5100, introduced in 1970 and produced in limited quantities until 1972. This model was equipped with the Beta-21 calibre, designed by the Centre Electronique Horloger (CEH), a consortium of around 20 Swiss watch manufacturers, including Rolex, to create the first Swiss quartz movement. 

As Rolex wanted to develop their own movement in-house, the first Oysterquartz models did not appear until 1977 with the Datejust (calibre 5035) and Day-Date (calibre 5055). The model we have here, the Oysterquartz Day-Date, reference 19018N, has a 36mm case in yellow gold with an integrated bracelet with flat links and a fluted bezel. Unlike the 19018 version, this model has no chamfers on the lugs and a vertical brushed polish on the upper part.

The calibre 5055 has a 32 khz oscillator (4 times more than the Beta-21) to compensate for the effects of temperature and guarantee an accuracy of less than one minute per year, far superior to that of all Rolex mechanical movements at the time. In addition, this calibre has a hacking-second function and dual date and day setting, which did not appear on automatic calibres until 1988.

The watch comes with a Rolex travel pouch, its Rolex certificate of origin (date of sale 1987), a 2009 Rolex service guarantee card and manuals.
