The world of luxury watches is rife with detail, and even minor discrepancies can spark significant debate among enthusiasts. A recent post on Oysterinfo.de regarding the Rolex Submariner 16610, specifically mentioning the surprising absence of an anti-reflective coating on its sapphire crystal, highlights a common area of confusion: the treatment, or lack thereof, of Rolex sapphire crystals. This article delves into the topic of "Rolex Saphirglas Entspiegelt" (Rolex sapphire crystal anti-reflective), exploring the history, the techniques, and the ongoing discussion surrounding the presence or absence of anti-reflective coatings on various Rolex models.
Saphirglas Nicht Entspiegelt???
The core question raised by the Oysterinfo.de post – "Saphirglas nicht entspiegelt???" (Sapphire crystal not anti-reflective???) – points to a key misunderstanding that many Rolex owners and prospective buyers grapple with. The assumption that *all* Rolex sapphire crystals are anti-reflective is incorrect. While Rolex utilizes sapphire crystals, known for their superior scratch resistance, the application of an anti-reflective coating has varied significantly across models and production years.
The absence of an anti-reflective coating on some Rolex watches isn't necessarily a defect or a sign of inferior quality. Historically, the technology and techniques for applying durable, high-quality anti-reflective coatings to sapphire crystals were less advanced and sometimes resulted in coatings that degraded over time or compromised the crystal's overall integrity. Therefore, Rolex, known for its conservative approach to innovation, opted in certain instances to forgo the coating rather than compromise the crystal's inherent robustness and longevity.
This explains why older Rolex models, including some examples of the 16610 as mentioned in the Oysterinfo.de report, may feature uncoated sapphire crystals. The glare from these crystals, especially in bright sunlight, can significantly impact legibility. This is a trade-off Rolex made – prioritizing scratch resistance over enhanced readability in specific periods.
Entspiegelung Gläser: The Evolution of Anti-Reflective Coatings
The term "Entspiegelung Gläser" (anti-reflective glasses) refers to the process of applying a thin coating to a lens or crystal surface to reduce light reflections. This dramatically improves clarity and visibility, particularly in bright conditions. The development of effective anti-reflective coatings for sapphire crystals has been an ongoing process, with significant advancements in materials science and application techniques leading to more durable and visually appealing results.
Early anti-reflective coatings were often less resistant to scratching and abrasion, prone to peeling or degradation over time. Modern techniques, however, utilize multiple layers of thin-film coatings, often involving materials like silicon dioxide or magnesium fluoride, to minimize reflections across a wider range of wavelengths. These multi-layer coatings offer superior durability and significantly reduce glare without compromising the scratch resistance of the underlying sapphire.
The evolution of these coatings is directly related to the changes observed in Rolex’s approach. As the technology improved, Rolex gradually incorporated anti-reflective coatings on more models, especially in their more contemporary collections. The decision to include or omit an anti-reflective coating wasn't arbitrary; it was a calculated decision based on the available technology and Rolex's stringent quality standards.
