Notes: This 36mm 18K yellow gold president was produced in the 1980s. It features a variety of dial designs including a striking blue jubilee face with Arabic hour marks. This watch was sold with a diamond hour mark option. Other hour marks include roman and index. The case, bezel and bracelet are all made in solid 18K yellow gold. The bezel on this model is smooth (non-fluted). The bracelet is typically a 3-link design. I have also seen these with leather straps, but that may be an owner modification due to loss, damage or personal preference.

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.
