Lume plots that have aged to a distinct orange or pumpkin-like color.

The "nipple dial" is a term used to describe a specific type of dial found on certain vintage Rolex watches, particularly the Rolex GMT-Master and Submariner models from the 1970s and 1980s. The distinguishing feature of a nipple dial is its hour markers: instead of the usual flat or applied markers, these dials have raised, gold-trimmed markers that resemble small "nipples." These markers are typically made of gold and are filled with luminous material, allowing them to be easily read in low-light conditions. The nipple dial is considered highly desirable among collectors due to its distinctive look and its association with vintage Rolex models.
