The Rolex Explorer II, a watch synonymous with exploration and adventure, received a subtle yet significant update in 2021. While not a radical redesign, the changes refined an already iconic timepiece, solidifying its position as a benchmark in professional tool watches. This article delves deep into the 2021 Rolex Explorer II (model number M226570-0001), exploring its features, specifications, and place within the broader Explorer II lineage. We'll also examine related topics such as size variations (including the often-asked about 36mm and 42mm models), release date, pricing, on-wrist aesthetics, the "polar" dial variant, and its impressive water resistance.
The 2021 Refinements: A Deeper Dive
The 2021 iteration of the Explorer II, available exclusively in the 42mm Oyster case, is immediately recognizable as its predecessor, yet closer inspection reveals subtle enhancements. The most significant change lies within the movement. The previous generation housed the calibre 3187; the 2021 model boasts the in-house calibre 3285, a testament to Rolex's commitment to constant improvement and innovation. This new movement represents a significant leap forward in terms of precision, chronometric performance, and power reserve.
The calibre 3285 is a Superlative Chronometer certified by COSC (Contrôle Officiel Suisse des Chronomètres), meaning it undergoes rigorous testing to ensure exceptional accuracy. Beyond the COSC certification, Rolex subjects its movements to further internal testing, guaranteeing even higher levels of precision. This "Superlative Chronometer" designation signifies a watch that surpasses the already stringent standards set by COSC. The improved power reserve offers approximately 70 hours of power, a significant upgrade compared to the previous model. This extended power reserve is particularly beneficial for adventurers and explorers who might not have immediate access to timekeeping adjustments.
While the external aesthetics remain largely unchanged, the 2021 model showcases Rolex's dedication to refining existing designs. The iconic orange hand remains a hallmark of the Explorer II, providing crucial readability in low-light conditions. The luminescence has also been improved, ensuring optimal visibility in challenging environments. The combination of the highly legible dial and the robust build makes the Explorer II a supremely practical and reliable tool watch. The watch's design philosophy is one of understated elegance, reflecting Rolex's commitment to functionality and durability above all else.
Size Variations: 36mm vs. 42mm
While the 2021 update focused on the 42mm model (M226570-0001), it's important to acknowledge the historical context and the existence of different size variations within the Explorer II family. The 42mm case size has been the standard for the modern Explorer II since its redesign in 2011. Before this, however, the Explorer II was available in a 36mm size, a model that has become highly sought after by collectors. The 36mm Explorer II offers a more compact and classic aesthetic, making it a suitable choice for those who prefer a smaller watch. However, the 36mm models are discontinued and only available on the secondary market.
