Day-Date 180** single quickset

In 1978 Rolex Rolex introduced the successor of the 1803 Day-Date, the 5-digit Day-Date with a single quickset function.

At first sight, the 180*** looks very similar to the 1803. The dial lost its pie-pan shape and in the 180** was the first to receive the sapphire crystal. It holds the more advanced Rolex caliber 3055 movement, which ticks at 28800vph and features a quickset for the date. This way, at least the wearer could quickly advance the date on his Day-Date. The weekday complication still needed to be set by moving the hour and minute hands. There are a lot of sub-references for the 18000 series, such as white and yellow gold, barked or with diamonds and not forgot about all the special configurations. The 18000-series is produced for 10 years, as the successor was introduced in 1988.

Here are some of the options, where the fifth digit always defines the material.
