Forum collectors document several distinctive aging patterns on 16803 dials, and blue dials in particular develop striking color shifts over decades of UV exposure and oxidation. Purple dials are blue dials that have shifted toward a deep purple or plum tone — a recognized tropical variant among two-tone Submariner collectors. Ghost grey dials have faded substantially, losing most of their blue saturation and settling into a pale, ghostly grey, and are sometimes called ghost dials. Denim blue dials have faded unevenly to a washed-out, textile-like blue reminiscent of worn denim.
 
* '''Purple''': blue dials that have shifted toward a deep purple or plum tone. This is a recognized tropical variant among two-tone Submariner collectors.
* '''Ghost grey''': blue dials that have faded substantially, losing most of their blue saturation and settling into a pale, ghostly grey. These are sometimes called “ghost” dials.
* '''Denim blue''': blue dials that have faded unevenly to a washed-out, textile-like blue reminiscent of worn denim.


These aging patterns are unpredictable and irreproducible, which gives well-aged examples a premium similar to the tropical phenomenon on vintage steel Submariners. The key authentication question with any color-changed dial is whether the aging is natural or artificially induced.
