The Rolex Explorer II, a watch synonymous with exploration and adventure, has undergone several subtle yet significant changes throughout its production history. One such area of evolution, often overlooked yet crucial to the watch's functionality and aesthetic appeal, is its luminous material. The 16570 reference, produced for 22 years, serves as a fascinating case study in this evolution, witnessing a transition from tritium to Luminova and finally to SuperLuminova. This article will delve into the intricacies of this luminous journey, exploring the differences between these materials, examining the performance of the 16570's luminous properties, and placing it within the broader context of Rolex's ongoing commitment to innovation in luminescence technology.
Rolex Luminous Evolution: A Timeline of Illumination
Rolex's history with luminous materials is as rich and varied as its watchmaking legacy. Early Rolex watches employed radium, a highly radioactive substance, for its luminescent properties. While effective, the inherent dangers of radium quickly became apparent, leading to its eventual phasing out. Tritium, a less radioactive isotope of hydrogen, emerged as a safer alternative, finding its way into many Rolex watches, including the early iterations of the Explorer II. Tritium offered a significantly improved safety profile compared to radium, but it also had a limited lifespan, gradually losing its luminance over time. This degradation was a factor that Rolex engineers constantly sought to improve upon.
The transition from tritium to Luminova marked a significant leap forward in luminous technology. Luminova, a non-radioactive, photoluminescent material, offered superior brightness and longevity compared to tritium. It absorbed ambient light and emitted a soft, consistent glow for extended periods, eliminating the gradual dimming associated with tritium. The shift to Luminova represented a crucial step towards enhancing both the safety and performance of Rolex's luminous displays.
The final stage in this evolution within the 16570's production run saw the adoption of SuperLuminova. Building upon the advancements of Luminova, SuperLuminova offered even greater brightness and persistence. This improvement meant that even after prolonged periods in darkness, the hands and markers of the Explorer II remained highly visible, enhancing readability and functionality in challenging conditions – a critical feature for the watch's intended use in exploration and adventure. The transition between Luminova and SuperLuminova within the 16570 production run is not always clearly documented and often requires careful examination of the watch itself to determine the specific luminous material used.
