The Rolex Explorer II 216570 stands as one of the most recognizable and capable tool watches in horological history. Introduced in 2011, this robust timepiece represents the culmination of decades of refinement, offering exceptional functionality wrapped in classic Rolex craftsmanship. Whether you’re a seasoned collector or considering your first luxury watch investment, understanding what makes this model special is essential.
The Heritage Behind the Explorer II
The Explorer II lineage dates back to 1971, designed specifically for spelunkers and polar explorers who needed to distinguish between day and night in environments without natural light. The 216570 continues this tradition while incorporating modern innovations that appeal to both adventure seekers and metropolitan professionals alike. Its distinctive orange 24-hour hand remains a signature feature, serving as both a functional tool and a visual hallmark.
Key Features That Define the 216570
The 42mm Case: Bold Yet Balanced
The 216570 features a 42mm case diameter, an increase from its predecessor’s 40mm. This sizing positions it perfectly for contemporary wrist preferences while maintaining the brand’s reputation for proportion and elegance. The case is crafted from Rolex’s proprietary 904L stainless steel, offering superior corrosion resistance and a lasting polish.
Movement Excellence: Caliber 3187
At the heart of the 216570 beats the Caliber 3187 movement, a self-winding mechanical movement with a power reserve of approximately 48 hours. This COSC-certified chronometer features a paramagnetic blue Paracrom hairspring, offering greater resistance to shocks and temperature variations—essential for any serious tool watch.
Legibility and Dial Options
Available in both black and white (polar) dial variants, the Explorer II prioritizes legibility above all else. The larger hour markers filled with Chromalight luminescent material ensure visibility in any lighting condition, while the date window at 3 o’clock provides practical everyday functionality.
Investment Considerations
When purchasing a Rolex Explorer II 216570, several factors merit consideration. The model was discontinued in 2021, replaced by the updated 226570 with the new Caliber 3285 movement. This discontinuation has created interesting dynamics in the secondary market, with certain dial variants experiencing increased collector interest.
The 216570’s value proposition remains strong due to its versatility—equally at home on mountain expeditions or in boardroom meetings. Its relatively accessible entry point compared to other Rolex Professional models makes it an attractive option for those seeking authentic tool watch pedigree without the premium attached to models like the Submariner or GMT-Master II.
Why the 216570 Remains Relevant
Despite being succeeded by the 226570, the 216570 continues to attract enthusiasts for several compelling reasons. Its slightly slimmer profile compared to the newer model appeals to those preferring a less bulky wrist presence. Additionally, the Caliber 3187, while not featuring the extended power reserve of its successor, has proven exceptionally reliable over the past decade.
Frequently Asked Questions
What’s the difference between the 216570 and 226570?
The primary differences include the movement (3187 vs. 3285), power reserve (48 vs. 70 hours), and subtle case profile changes. The 226570 also features an updated bracelet with Easylink extension.
Is the 42mm case too large for smaller wrists?
While 42mm is substantial, the Explorer II’s short lugs and balanced proportions allow it to wear comfortably on wrists as small as 6.5 inches. Try before buying when possible.
Which dial color holds value better?
Historically, both dials perform similarly in terms of value retention. The polar dial often commands slight premiums due to its distinctive appearance and perceived rarity.
Can I swim with the Explorer II 216570?
Yes, with 100 meters (330 feet) of water resistance and a screw-down crown, the watch is suitable for swimming and recreational water activities.
How often does the 216570 require servicing?
Rolex recommends servicing every 10 years under normal wearing conditions, though regular use and care can extend this interval.
Conclusion
The Rolex Explorer II 216570 represents a sweet spot in the brand’s catalog—sophisticated enough for formal occasions yet purpose-built for genuine adventure. Its discontinuation hasn’t diminished its appeal; rather, it has solidified its status as a modern classic. Whether you value its technical specifications, timeless design, or investment potential, the 216570 continues to deliver on every front. For those seeking a versatile, reliable companion that embodies Rolex’s tool watch philosophy without excessive premium pricing, this model deserves serious consideration.
