勞力士，非常罕有，18k金自動上弦腕錶，配中心秒針、星期、日曆顯示及珊瑚錶盤，“Day-Date”，型號18038，約1982年製

The most significant trait of this watch, making it extremely attractive and sought after, is its enthralling red coral dial. Due to the natural variation in rock formation, each example fitted with a coral dial is unique, with each exhibiting a different veined texture to the last. This feature is so important that Rolex even removed all numerals from the dial to draw attention to it, resulting in a clean (yet far from dull) design.
