SIGNED ROLEX, DAY-DATE MODEL, REF. 18238, CASE NO. L410513, CIRCA 1989

The most significant trait of this watch, making it extremely attractive and sought after, is its enthralling red coral dial which is the part of the rarest dials ever created by Rolex. Due to the natural variation in rock formation, each example fitted with a coral dial is unique, with each example exhibiting a different veined texture.

This feature is so important and fragile that Rolex even removed all numerals from the dial to draw attention to it, resulting in a clean design.
