Hoseachandra's acquisition of a Rolex Explorer II Ref. 16570, specifically a V-series from 2009, highlights a significant point in the model's history. This particular reference, being one of the last before the transition to the larger 42mm 'maxi case,' represents a desirable iteration for collectors. His detailed post offers valuable insights into the specific features that make this late-production 16570 a noteworthy piece.

The Explorer II reference 16570 represents a significant evolution within the Explorer II line, succeeding the 16550 and introducing updated aesthetics and technical refinements. It maintained the core utility of a robust tool watch designed for explorers and those who operate in environments where distinguishing day from night is challenging, thanks to its 24-hour hand and fixed bezel. This reference is often considered a modern classic, bridging the gap between earlier vintage models and contemporary Rolex offerings.
This reference features a 40mm stainless steel case, housing either the Caliber 3185 or later the Caliber 3186 automatic movement, providing a power reserve of approximately 48 hours. It is fitted with a sapphire crystal, enhancing durability and scratch resistance compared to earlier acrylic crystals. The watch offers a water resistance of 100 meters, suitable for everyday wear and light water activities, and is paired with a fixed stainless steel bezel engraved with 24-hour markers.
Appealing to collectors who value a blend of functionality and understated design, the 16570 is available with either a black or white dial, the latter often referred to as the "Polar" dial. Its production run saw the transition between different calibers, which can be a point of interest for enthusiasts. The reference is a practical choice for those seeking a GMT complication in a durable and recognizable form factor, without the rotating bezel found on other GMT models.
congratulations, Best Ashot
The Explorer ii is “the” sports Rolex. The 40mm case size is right up my alley, can’t fit the new maxi case on my mini wrist. With your new datejust this might be a 2 watch collection to cover nearly all the bases.
Wear it in the best of health.
Here’s my “U” serial from 1997. I love the Explorer II.
You must taking care of that watch very seriously.
Fact it it doesn’t get much wrist time unfortunately because I want to keep it perfect. 👍
