In 1980, the GMT-Master saw its first new reference numbers in over two decades, in the steel reference 16750 and gold reference 16758. Both of these watches featured an upgraded movement 3075, with a higher 28,800vph frequency and quick-set date, and a doubled water-resistance rating of 100m.Launched in 1977, the Rolex President ref. 18038 introduced some improvements to the Day-Date line. In addition to now being furnished with a sapphire crystal, the Day-Date ref. 18038 also included the quickset date feature. Powering the Rolex ref. 18038 was the new Caliber 3055.The “quick set” feature on the Day-Date, allowing rapid setting of the date, debuted with calibre 3055 in ref. 18026 in the late 1970s. The “double quick set” calibre 3155 was introduced in 1988.

With it, the wearer can correct both the date and day display separately from the time. 2000: Rolex rolls out the six-digit Day-Date, the reference 118XXX. In this instance, the improvements were reserved for the bracelet and clasp. The brand’s next innovation came in 1932 with the invention of the Perpetual Rotor, the piece that now forms the backbone of all automatic watches.
