The Rolex Explorer II, particularly the reference 16570, holds a special place in the hearts of many watch enthusiasts. Its rugged design, robust functionality, and association with exploration make it a highly sought-after timepiece. For many, the choice to acquire a 16570 signifies not just a purchase, but the commencement of a lifelong journey into the world of horological excellence. This article will delve into the specifics of the sapphire crystal used in the Explorer II, exploring its history within the context of Rolex's overall crystal development, and addressing common questions surrounding its durability, replacement, and aesthetic appeal.
The Explorer II (16570) Sapphire Crystal: A Foundation of Durability
Our journey begins with the statement: "I have decided that my first Rolex will be the Polar Explorer 2." This simple declaration encapsulates the allure of the Explorer II, particularly the coveted "Polar" dial variant of the 16570. This model, produced from 1989 to 2011, represents a significant chapter in Rolex's history, marked by a transition towards the widespread adoption of sapphire crystals. The sapphire crystal crowning the 16570 isn't just a protective cover; it's a testament to Rolex's commitment to both functionality and visual appeal. Its exceptional hardness makes it highly resistant to scratches, a crucial feature for a watch designed to withstand the rigors of exploration and daily wear. This inherent durability contributes significantly to the watch's longevity, ensuring that the dial and movement remain protected from the elements and the inevitable knocks and bumps of life. The clarity of the sapphire crystal also allows for an unimpeded view of the dial, enhancing the overall aesthetic experience.
From Acrylic to Sapphire: A Rolex Crystal Odyssey
Understanding the significance of the sapphire crystal on the 16570 requires a brief exploration of Rolex's crystal history. Early Rolex watches, like many other watches of their era, utilized acrylic crystals. Acrylic, while relatively inexpensive and easy to work with, was significantly more susceptible to scratches and damage compared to sapphire. This limitation meant that the crystal, a crucial component protecting the watch's delicate internal mechanisms, was prone to deterioration over time, affecting both the watch's appearance and functionality.
Rolex Sapphire Crystal History: A Gradual Transition
The transition to sapphire crystals by Rolex wasn't an immediate shift. It was a gradual process, driven by advancements in material science and a commitment to improving the durability and longevity of their watches. While the exact timeline is complex, encompassing variations across different models and production runs, the adoption of sapphire crystals became increasingly prevalent throughout the latter half of the 20th century. The inherent advantages of sapphire – superior scratch resistance, clarity, and durability – made it a natural choice for a brand committed to producing timepieces of exceptional quality and resilience.
Rolex 16800 Sapphire Crystal: A Precursor to the Explorer II
While the 16570 cemented the use of sapphire crystals in the Explorer II line, other Rolex models paved the way. The Rolex Submariner, for example, adopted sapphire crystals in some of its references, including the 16800, well before the 16570's introduction. This demonstrates Rolex's progressive approach to material selection, testing and implementing new technologies across its range before integrating them into specific models like the Explorer II. The 16800's sapphire crystal experience provided valuable data and insights that informed the decision to equip the 16570 with this superior material.
