Notes: This is a Rolex 36mm Day-Date president produced from the late 1970s through the 1980s. It is made with in solid 18k yellow gold with a matching 18k yellow gold bracelet. One version features a fluted 18k yellow gold bezel and index hour marks. A fancier version features a diamond bezel (1.00 ct total weight) with diamond hour marks. An even fancier version features a layer of pave diamonds as the dial face with sapphires as the hour marks (and also has diamonds set in the bezel). Dial face colors appear to be champagne and black for the most part.

These is one insane variation of this watch with diamonds covering the bracelet, baguette diamonds on the dial, diamonds set in the band lugs and pave diamonds on the face (see picture gallery). This variation is referred to as the "Super President".

Mechanism: The Cal. 3055 released in 1977, it formed part of the 3000 series of movements that ushered in the high beat frequency era, giving the emblematic flowing seconds hand of all latter day Rolexes. It was the fifth generation Rolex Day-Date movement The Cal. 3055 brought many changes for both the day and the date functions but, as a single Quickset movement, only the date could be adjusted with the crown An unusual aspect of the Cal. 3055 is, unlike the vast majority of Rolex’s engines, it was only ever used in one model of watch. This was the 1977 edition of the 18038 Day-Date.

Family Notes: The Rolex Day-Date was introduced in 1956. It soon became known as the "Rolex President". It was unofficially renamed after President Eisenhower became associated with this model watch. This association was made as the watch was known to have been worn by LBJ and shared a scandalous connection to JFK. Since then it has earned the vote of a diverse array of potentates, including Warren Buffett, Jay Z, and (fictional character) Tony Soprano. In 1977, Rolex started using the new (at the time) 3055 movement for the Day-Date/President line. As of 2018, the Day-Date 40 uses the 3255 movement.
