Rolex Tropical Blue Dial for Submariner 16803 | 16808 16613 | 16618 Tritium

The Rolex "Tropical Blue Dial" for Submariner models such as the 16803, 16808, 16613, and 16618 is a unique and fascinating phenomenon in the world of watch collectors. These dials are extremely rare in the dark blue fading. We ourselves have only seen this once before. Originally not labeled as "tropical," the term evolved to describe dials that have undergone color changes due to aging and environmental influences.
