The Rolex Explorer II, a watch synonymous with exploration and rugged durability, has captivated watch enthusiasts for decades. This article focuses specifically on the reference 216570, a model that represents a significant evolution in the Explorer II lineage, refining its design and performance while retaining the core spirit of adventure that defines the line. We'll delve into its specifications, explore its design elements, examine its market price, and compare it to other models to provide a comprehensive understanding of this highly sought-after timepiece.
Design and Aesthetics: A Modern Classic
The Rolex Explorer II ref. 216570 boasts a robust 42mm Oyster case crafted from 904L stainless steel, a material known for its exceptional corrosion resistance and scratch resistance. This substantial size, a departure from earlier, more compact Explorer II models, provides excellent wrist presence and legibility. The iconic fixed bezel, a key feature distinguishing the Explorer II from its Explorer sibling, is crafted from scratch-resistant ceramic and features a highly legible 24-hour graduated scale. This 24-hour bezel is crucial for adventurers, allowing for easy differentiation between day and night, especially in challenging conditions with limited light. The luminescent numerals and markers on the bezel, along with the highly luminous hour markers and hands, ensure optimal readability in low-light environments, a critical feature for any tool watch intended for exploration.
The dial, available in black, is clean and functional, featuring bold, easily discernible hour markers filled with Chromalight luminescent material. The date window at 3 o'clock is subtly integrated into the design, maintaining the overall balance and legibility of the dial. The hands, with their distinctive design, are also coated with Chromalight, maximizing visibility in the dark. The overall aesthetic is one of understated elegance and rugged functionality, a perfect blend of style and purpose. The watch's design is both timeless and contemporary, making it a versatile timepiece suitable for a wide range of occasions, from navigating treacherous terrain to attending a formal event.
Movement and Performance: The Caliber 3187
Powering the Rolex Explorer II ref. 216570 is the in-house caliber 3187, a self-winding mechanical movement that exemplifies Rolex's commitment to precision and reliability. This movement features a Parachrom hairspring, a patented Rolex innovation made from a paramagnetic alloy that is significantly more resistant to shocks and magnetic fields than traditional hairsprings. This contributes to the watch's exceptional accuracy and stability, ensuring reliable timekeeping even under extreme conditions. The caliber 3187 also incorporates a high-performance shock absorber, further enhancing its robustness and resistance to impacts. The movement boasts a power reserve of approximately 48 hours, providing ample timekeeping even if the watch is not worn for a period. Its superior performance and reliability make it a dependable companion for any adventure.
