The Rolex Explorer II, specifically the 42mm model with a black dial (reference 226570), stands as a testament to Rolex's unwavering commitment to robust, reliable, and highly legible timekeeping. This iconic tool watch, designed for exploration and adventure, boasts a compelling blend of functionality, durability, and timeless elegance. This article delves deep into the nuances of this particular model, exploring its features, history, price, and overall value proposition. We'll also address frequently asked questions concerning its release date, thickness, and current market value.
A Legacy of Exploration:
The Explorer II's history is intrinsically linked to exploration. Its origins trace back to the 1970s, when Rolex sought to create a watch specifically designed to meet the demands of cave explorers and other adventurers operating in challenging environments. The original Explorer II featured a distinct 24-hour hand, a crucial element for differentiating between day and night in low-light conditions, a feature that remains a hallmark of the model to this day. This crucial addition allows for easy tracking of a second time zone, proving invaluable in diverse situations.
The current 42mm iteration (reference 226570) represents a refined evolution of this legacy. While maintaining the core functionality and rugged design philosophy, Rolex has incorporated modern advancements in materials and manufacturing techniques to create a watch that is even more robust and reliable than its predecessors.
Design and Features:
The Rolex Explorer II 226570 boasts a 42mm Oyster case crafted from Oystersteel, a proprietary stainless steel alloy known for its exceptional strength and corrosion resistance. This substantial case provides excellent protection for the watch's intricate movement. The highly legible black dial features large, luminous hour markers and hands, ensuring excellent readability even in the darkest conditions. The iconic 24-hour hand, in orange, stands out against the black dial, a clear visual indicator of a second time zone or the time in a different location.
The watch is fitted with a scratch-resistant sapphire crystal, protecting the dial from impacts and scratches. The unidirectional rotating bezel, also crafted from Oystersteel, provides a secure and intuitive way to track elapsed time. The bezel's markings are crisp and easy to read, further enhancing the watch's practicality. The Oyster bracelet, secured with a robust Oysterlock clasp, ensures a comfortable and secure fit on the wrist. The bracelet's design incorporates comfort extension links, allowing for easy adjustment to accommodate changes in wrist size due to temperature fluctuations or swelling.
The Calibre 3285 Movement:
Powering this formidable timepiece is the self-winding mechanical calibre 3285 movement, entirely developed and manufactured by Rolex. This movement is a marvel of horological engineering, boasting exceptional precision, reliability, and power reserve. The calibre 3285 incorporates numerous patented technologies, including the Chronergy escapement, which is significantly more efficient and resistant to shocks than traditional escapements. It also features a Parachrom hairspring, made from a paramagnetic alloy, which is virtually impervious to magnetic fields and offers superior resistance to shocks and temperature variations. These technological advancements ensure exceptional accuracy and long-term performance. The power reserve is approximately 70 hours, allowing the wearer to take the watch off for a weekend without needing to reset the time.
