The Rolex Submariner, a watch synonymous with diving prowess and enduring style, is renowned for its robust construction and exceptional quality. However, even these iconic timepieces aren't immune to the effects of time and wear. One issue that some owners have reported is discoloration of the bezel insert, specifically the luminous pearl or dot located at the 12 o'clock position. The German phrase "Rolex Submariner Lünette verliert Farbe," which translates to "Rolex Submariner bezel loses color," succinctly describes this phenomenon. This article will delve into the causes, potential solutions, and broader implications of bezel discoloration on the Rolex Submariner, focusing particularly on the observed browning or yellowing of the luminous pearl.
The observation, "Dabei musste ich feststellen das der Lume Dot in der Lünette meiner DS 116660 D Blue etwas vergilbt ausschaut bzw. bräunliche Verfärbungen vom Rand her aufweist," highlights a common concern: a yellowing or browning of the luminous pearl on a Deepsea Sea-Dweller (DS 116660 D Blue) bezel. This isn't unique to this specific model; similar discoloration has been reported across various Submariner models, including the newer ceramic Cerachrom bezels.
Understanding the Rolex Submariner Bezel Insert:
Before delving into the discoloration issue, let's briefly examine the construction of the Submariner bezel. Older models featured aluminum bezel inserts, susceptible to fading, scratching, and discoloration over time. The introduction of the Cerachrom bezel insert, a high-tech ceramic material, significantly improved durability and resistance to fading. However, while Cerachrom is remarkably resistant to scratches and UV damage, it's not entirely impervious to all forms of degradation.
The luminous pearl or dot, a crucial element for underwater readability, is often the first part of the bezel insert to show signs of aging. This is because the luminescent material used, typically a type of luminescent paint, is more susceptible to degradation than the ceramic itself. This degradation can manifest as yellowing, browning, or a loss of luminosity over time.
Causes of Rolex Submariner Bezel Discoloration:
Several factors contribute to the discoloration of the Submariner bezel insert, particularly the luminous pearl:
* UV Exposure: Prolonged exposure to ultraviolet (UV) radiation from sunlight is a primary culprit. UV rays can break down the chemical structure of the luminescent material, causing it to yellow or brown. This is particularly relevant for watches frequently worn outdoors.
* Exposure to Chemicals: Contact with certain chemicals, such as chlorine in swimming pools or harsh cleaning agents, can also affect the bezel's color and the luminous paint. Even seemingly innocuous substances can, over time, cause degradation.
* Age and Wear: Like any material, the luminescent paint naturally degrades over time. This is a gradual process, but it's inevitable. The rate of degradation can be influenced by the factors mentioned above.
* Manufacturing Variations: Although rare, subtle variations in the manufacturing process could lead to inconsistencies in the luminescent material's stability and resistance to discoloration.
* Storage Conditions: Improper storage, such as exposure to high temperatures or humidity, can accelerate the aging process and contribute to discoloration.
