I am new to this forum and this is my first post. I am looking for some genuine advice from fellow Rolex enthusiasts. I purchased my first Rolex Submariner Date three months ago, and I'm absolutely loving it. This experience has ignited a passion for understanding the intricacies of my watch, particularly its sapphire crystal. This article delves into the fascinating history of Rolex sapphire crystals, focusing specifically on untreated examples, and explores the options available for replacement should the need arise.
Rolex Sapphire Crystals: A Technological Leap
Before diving into the specifics of untreated sapphire crystals, let's establish the broader context of Rolex's adoption and utilization of this material. For decades, Rolex, like many other watchmakers, relied on acrylic (plexiglass) crystals. Acrylic, while relatively scratch-resistant compared to glass, was susceptible to more significant damage and prone to developing unsightly scratches over time. The introduction of sapphire crystals marked a significant advancement in watchmaking technology.
Sapphire, a crystalline form of aluminum oxide (Al2O3), boasts an exceptional Mohs hardness rating of 9, second only to diamond. This exceptional hardness translates to unparalleled scratch resistance, making sapphire crystals virtually impervious to everyday wear and tear. This durability was a game-changer for Rolex, ensuring the long-term preservation of the watch's dial and hands, and enhancing its overall longevity. The transition from acrylic to sapphire wasn't immediate; it was a gradual process, reflecting the technological advancements and manufacturing capabilities of the time.
Rolex Sapphire Crystal History: A Gradual Transition
The precise timeline of Rolex's adoption of sapphire crystals is not publicly documented with absolute precision, but historical evidence suggests a phased implementation. Early Rolex models, including many iconic Submariners, featured acrylic crystals. These acrylic crystals, while less durable, offered a certain charm and character that some collectors appreciate today. The warm, slightly softer look of an acrylic crystal, contrasted with the sharper, clearer appearance of sapphire, is a point of discussion amongst enthusiasts.
The shift towards sapphire began gradually, with Rolex likely experimenting and refining its manufacturing processes before widespread adoption. This transition period is crucial for understanding the variations found in vintage and modern Rolex watches. The exact year a specific model transitioned to sapphire is often a subject of debate among collectors, underscoring the nuanced history of Rolex crystal production.
Rolex Sapphire Crystal 1970s: A Decade of Transition
The 1970s represent a significant period in Rolex's sapphire crystal journey. While not universally adopted across all models, the decade witnessed a notable increase in the use of sapphire crystals in various Rolex lines, including the Submariner. Identifying whether a particular 1970s Submariner features an acrylic or sapphire crystal requires careful examination of the watch itself, often involving magnification and comparison with known examples. The presence of a sapphire crystal on a 1970s Submariner is often considered highly desirable by collectors, further highlighting the significance of this material in Rolex's history.
