The Rolex Submariner Date, a watch synonymous with diving prowess and enduring style, boasts a crucial element often overlooked by the casual observer: its 904L stainless steel construction. This isn't just any stainless steel; 904L possesses unique properties that contribute significantly to the watch's exceptional durability, corrosion resistance, and lustrous appearance, setting it apart from many competitors. This article delves into the reasons behind Rolex's dedication to 904L steel, exploring its benefits and examining the historical and current market values of Rolex Submariners, including the coveted Date models.
The Superiority of 904L Stainless Steel
While many watch brands utilize 316L stainless steel, Rolex opted for the more advanced 904L. This decision reflects the brand's unwavering commitment to quality and longevity. 904L, also known as "Oystersteel," offers several key advantages:
* Exceptional Corrosion Resistance: 904L boasts significantly higher corrosion resistance compared to 316L. This is crucial for a watch designed to withstand the harsh conditions of underwater exploration, as well as the daily wear and tear of terrestrial life. The increased chromium, molybdenum, and nickel content in 904L creates a denser, more protective oxide layer, shielding the steel from oxidation and environmental degradation. This translates to a watch that retains its pristine appearance for years, even decades, with proper care.
* Enhanced Polishability and Lustrous Finish: 904L takes a superior polish, yielding a brighter, more reflective surface than 316L. This characteristic contributes to the iconic gleam of Rolex watches, enhancing their aesthetic appeal. The smoother surface also makes the watch more resistant to scratching, further contributing to its longevity.
* Superior Strength and Durability: While the difference isn't dramatic, 904L generally exhibits slightly higher strength and hardness than 316L. This contributes to the overall robustness and resilience of the watch, protecting the internal mechanism from damage caused by shocks and impacts.
* Increased Resistance to Staining: The superior corrosion resistance of 904L translates to a reduced susceptibility to staining from common substances like sweat, seawater, and various chemicals. This ensures the watch maintains its elegant appearance even after prolonged exposure to different environments.
The Historical Context: Pricing and Value of Rolex Submariners
Understanding the current value of a Rolex Submariner Date requires a look back at its history. The prices of vintage Rolex watches, particularly those from the 1990s, have experienced remarkable appreciation. Let's examine the price landscape of Rolex watches, particularly Submariners and Datejusts, from that era:
* Rolex Price in 1990: The prices of Rolex watches in 1990 were significantly lower than today's values. A new Rolex Submariner Date would have been considerably more affordable than its current counterpart. The exact price varied depending on the specific model and retailer, but it was generally within a range that made it a more accessible luxury item than it is now.
