The Rolex Explorer II, particularly the reference 16570 produced between 1989 and 2011, holds a special place in the hearts of many watch enthusiasts. Its rugged design, robust functionality, and distinct orange hand make it an iconic timepiece. But for collectors and aficionados, a key element of fascination lies in the luminescent material used in these watches: tritium. This article delves into the world of the Rolex Explorer II 16570 with tritium, exploring its characteristics, the allure of its aged lume, and the ongoing discussions surrounding its potential for yellowing.
The Allure of Tritium:
Before the advent of modern Super-LumiNova, tritium was the dominant luminescent material used in watches. Unlike Super-LumiNova, which requires external light exposure to charge, tritium is self-powered, emitting a soft, constant glow thanks to radioactive decay. This constant luminescence, often described as a "ghostly" or "ethereal" glow, is a significant part of the charm of vintage tritium watches, including the 16570 Explorer II. The soft glow, unlike the sometimes harsh brightness of modern lume, provides a subtle and elegant readability even in low-light conditions. However, this very characteristic is also a source of ongoing discussion and debate among collectors.
The 16570 Explorer II: A Detailed Look:
The Rolex Explorer II reference 16570, produced for over two decades, represents a significant chapter in the Explorer II's history. It refined the design elements established by its predecessors, offering a robust and reliable tool watch perfectly suited for exploration and adventure. Key features of the 16570 include:
* The iconic 24-hour hand: A hallmark of the Explorer II, this hand allows for easy distinction between AM and PM, crucial in challenging environments. The vibrant orange color of this hand, often described as a fiery orange, contrasts beautifully against the black dial, enhancing readability.
* Robust construction: The 16570 boasts a 40mm Oyster case, known for its water resistance and durability. The sapphire crystal protects the dial from scratches, while the screw-down crown ensures water tightness.
* Caliber 3185 movement: This highly reliable and accurate automatic movement is a testament to Rolex's commitment to precision and performance. It offers a power reserve of approximately 48 hours.
* Tritium lume: As mentioned earlier, the 16570 typically features tritium lume on the hour markers and hands. This is a key aspect distinguishing it from later models using Super-LumiNova.
