About the Rolex Explorer II 226570
The Rolex Explorer II has a storied heritage tracing back to 1971, originally designed for cavers and polar explorers who needed to tell AM from PM in environments where daylight is absent or constant. The 226570 represents the latest chapter in that story, launched with a 42 mm Oystersteel case, a domed sapphire crystal with anti-reflective coating, and a prominent Mercedes-style hour hand paired with a dedicated 24-hour hand on a Chromalight-filled dial. Black dial references carry a bold, utilitarian character while the white dial, often called the Polar, maintains the model's most recognizable and collectible aesthetic. The fixed stainless steel 24-hour bezel remains the defining visual signature that separates the Explorer II from every other Rolex sports model.
What to Look For
When shopping the 226570 collection, the primary choice is dial color: white dial examples such as the 226570WLO offer the classic Polar look that commands strong collector demand, while black dial references like the 226570B1 and 226570BLO deliver a more aggressive, tool-watch aesthetic. Aftermarket PVD and DLC variants such as the 226570PVD broaden the style palette with a stealth all-black finish that is not available from Rolex directly, making them a niche but popular choice for buyers seeking a more custom look. Condition, original box and papers, and the quality of any aftermarket coating work are the key value drivers across this reference.
Frequently Asked Questions
What is the case size of the Rolex Explorer II 226570?
The 226570 features a 42 mm Oystersteel case, a size that Rolex settled on for the Explorer II with the 216570 generation and carried forward into this current reference. The 42 mm diameter strikes a balance between wrist presence and wearability, making it one of the larger tool watches in the Rolex sports lineup.
What is the difference between the white dial and black dial 226570?
The white dial 226570, sometimes called the Polar, is widely regarded as the more collectible configuration and references the iconic 1989 Explorer II 16570 Polar edition that gained cult status among enthusiasts. The black dial version offers stronger contrast on the Chromalight-filled indices and appeals to buyers who prefer a more utilitarian, tool-watch aesthetic. Both share identical case dimensions, bezel, and movement.
Are the PVD and DLC 226570 models original Rolex factory finishes?
No, PVD and DLC coatings on the 226570 are aftermarket treatments applied by specialist third-party companies and are not offered by Rolex directly. These finishes can produce a striking all-black look but buyers should understand they fall outside the factory specification, which can affect value and serviceability. Bizak and Co. clearly identifies these variants in the listing titles so buyers know exactly what they are purchasing.
