The question, "Ab Wann Hat Rolex Saphirglas?" – "When did Rolex start using sapphire crystals?" – is a frequently asked one among watch enthusiasts. While the answer isn't a single, definitive date, the journey of sapphire crystal integration into Rolex watches is a fascinating chapter in the brand's history, marked by gradual adoption and technological advancements. This article explores the timeline, examining key models and the broader context of Rolex's sapphire crystal history.
The Rise of Sapphire Crystal Rolex: A Technological Leap
Before delving into specific dates, it's crucial to understand the significance of sapphire crystal in watchmaking. Prior to its widespread adoption, acrylic (plexiglass) was the dominant material for watch crystals. While relatively inexpensive and scratch-resistant compared to glass, acrylic was prone to more significant damage, including cracking under impact. Sapphire, a crystalline form of aluminum oxide, offered a superior alternative. Its hardness (9 on the Mohs scale, second only to diamond) made it exceptionally resistant to scratches, significantly enhancing the watch's durability and maintaining its aesthetic appeal over time. However, the manufacturing process of sapphire crystals was complex and expensive, delaying its widespread use in the watch industry.
Rolex Sapphire Crystal History: A Gradual Transition
Rolex, a brand synonymous with precision and durability, recognized the advantages of sapphire crystal early on. However, their adoption wasn't a sudden shift. The transition was gradual, driven by technological advancements in sapphire crystal production and Rolex's meticulous testing and quality control processes. They weren't simply going to replace a material unless they were convinced the alternative was demonstrably superior and wouldn't compromise other aspects of their watches.
Rolex Sapphire Crystal 1970s: The Dawn of a New Era
The 1970s mark a pivotal decade in Rolex's sapphire crystal journey. While the exact date remains a subject of some debate among collectors, the generally accepted starting point for the widespread adoption of sapphire crystals in Rolex watches is the late 1970s. This period witnessed significant advancements in sapphire crystal manufacturing, making it more feasible for large-scale production and integration into premium timepieces.
The Rolex Submariner Date Ref. 16800: A Landmark Moment
The commonly cited milestone is the introduction of the Rolex Submariner Date ref. 16800 in 1979. This model is widely considered the first commercially available Rolex Submariner to feature a sapphire crystal. This marked a significant upgrade for the iconic diver's watch, offering superior scratch resistance and improved clarity compared to its acrylic-crystal predecessors. The decision to equip the Submariner Date with sapphire crystal was strategic. The Submariner, a professional diver's watch, demanded maximum durability, and the sapphire crystal perfectly complemented this requirement. The enhanced scratch resistance was crucial for a watch frequently subjected to harsh underwater environments.
The No-Date Submariner: Following Suit
Following closely behind the Submariner Date ref. 16800, the no-date Submariner also transitioned to sapphire crystal. While the precise year is less definitively documented, the shift likely occurred shortly after the introduction of the 16800, solidifying sapphire crystal as the standard for the Submariner line. The no-date model, appreciated for its minimalist design and purist appeal, benefited equally from the enhanced protection offered by the sapphire crystal.
