Rolex Explorer II Stainless Steel / Black 226570-0002

 The Explorer II 226570 Black Dial made its debut in 2021, picking up right where the previous model left off. But this isn’t just a rehash of what came before – Rolex has kept everything that makes the Explorer II special while making sure the 226570 stands out with subtle updates that improve wearability and style. It is a watch that still holds true to its tough roots, but it is built to take on whatever life demands, from the toughest tasks to everyday moments.

The 226570 keeps the 42mm case size from the 216570, but now it fits better, feels more comfortable, and looks even sleeker. With slightly slimmer lugs and a slightly wider bracelet, the watch sits evenly on the wrist – still tough, but with a more elevated look.

Let’s now take a look at the history behind the Explorer II and how it became the trusted tool it is today.

Watch our tour video about the Rolex Explorer 2 Black 226570-0002.

The Explorer II has been around since 1971, created for explorers who needed a reliable way to track time in extreme environments. The original model, the 1655, was designed for cave explorers and polar adventurers who couldn’t rely on traditional timekeeping methods in places where it is either dark all the time or light all the time. The watch featured a 24-hour display and a fixed bezel with 24-hour markings, making it easy to tell whether it was day or night – especially when both could look the same.

Over the years, the Explorer II has gone through several updates, with each new generation improving on its core design while maintaining the rugged functionality that made it a favorite among adventurers. The 16570, released in the late ’80s, was the next big step, offering updated movements and a more modern look. Then came the 216570, which introduced a 42mm case and further improved the watch’s durability and wearability, continuing its legacy as the tool of choice for those in tough conditions.

Fast forward to 2021, and the 226570 was launched to mark the 50th anniversary of the Explorer II. This new version keeps the core elements that made the original so reliable, like the 24-hour hand and fixed bezel, but also brings some thoughtful updates. The movement has been upgraded for better accuracy and power reserve, and the case is slightly slimmer for more comfort. These updates make the 226570 even more wearable for everyday use, while keeping the same rugged design that made the Explorer II the go-to tool for adventurers.

Now, let’s explore how the case and strap have been updated in this version, enhancing its fit and performance for both everyday use and demanding outdoor activities.

Case & Strap

With a 42mm case size, the 226570 strikes the perfect balance – not too large, yet still bold enough to make a statement. The case is made from 904L steel, a material Rolex uses for its superior resistance to corrosion, making it an excellent choice for a watch built to withstand extreme conditions like spelunking or polar expeditions.

One key update in the 226570 is the slimmer lug profile. Rolex has reduced the width of the lugs slightly, which helps the watch wear more comfortably and creates a more proportionate look when paired with the redesigned 22mm Oyster bracelet. This updated bracelet is wider than previous models, providing a more secure fit. The bracelet features brushed links throughout, offering a clean, cohesive design that complements its overall appearance.

The widened end links provide a smoother transition from the case to the bracelet, ensuring that the watch fits more naturally around the wrist and enhances overall comfort. The Easylink comfort extension link is another standout feature. It allows you to adjust the bracelet by 5mm without any tools – perfect for getting a quick fit adjustment if your wrist changes size due to heat or physical activity, making the watch even more versatile and comfortable throughout the day.

Since the 226570 has a 22mm lug width, you can easily swap the bracelet for other straps, like leather or rubber, depending on your style or activity. This gives you the flexibility to customize the watch for different occasions or conditions.

Having covered the case and strap, let’s move on to the dial design, which blends both clarity and practicality, ensuring the watch is ready for any adventure.

The black dial of the 226570 continues the tradition of the Explorer II with a design that prioritizes legibility and function. The dial features the signature orange 24-hour hand, making it easy to track a second time zone. This remains a standout feature, staying true to the original design of the Explorer II. The orange text reading “Explorer II” on the dial adds an extra touch of color for visibility, while also reflecting the spirit of this tool watch.

The hour and minute hands are crafted from high-polished white gold, an update that improves durability by preventing tarnishing, ensuring the hands will stay clear and readable over time. This subtle change also enhances the overall appearance against the black dial.

As with previous models, Chromalight lume is applied to all hands and markers, providing a bright blue glow in the dark. So, whether you’re on a cave expedition or just out at night, the lume ensures readability even in low-light conditions. The Cyclops lens at the 3 o’clock position magnifies the date for easier reading, making it a useful feature when you need to check the date quickly in any environment.

Now that we’ve covered the dial design, let’s take a look at the movement and functionality of the Explorer II 226570, which has been upgraded for even better performance.

Under the hood of the 226570, you’ll find the Rolex Caliber 3285, an upgraded movement that takes the place of the previous Caliber 3187. One of the standout improvements is the Chronergy escapement, which makes the movement more efficient and boosts its power reserve. With a 70-hour power reserve, this means if you don’t wear it for a couple of days, it’s still good to go when you pick it up – no winding required.

The movement also features the blue Parachrom hairspring, which is resistant to shocks and magnetic fields, ensuring the watch keeps accurate time, no matter what extreme environments you’re in. And with the Paraflex shock system, even sudden impacts won’t throw it off track, making it the perfect choice for those who need a reliable watch for both everyday bumps and extreme adventures.

As with previous models, the 226570 retains its signature dual-time zone functionality. The orange 24-hour hand can be adjusted independently of the 12-hour hand, so tracking two time zones is a breeze. The fixed 24-hour bezel also helps you tell the difference between AM and PM, especially in places where it’s hard to distinguish between the two, like caves or polar regions.

With all these enhancements to functionality, it is clear the 226570 is ready for whatever comes its way. But what good is a tool watch if it doesn’t feel comfortable on the wrist? Let’s dive into how the Explorer II wears and feels, both in everyday situations and more adventurous settings.

Even though it has a 42mm case size, it wears much more comfortably than you’d expect. The thinner lug profile helps the watch feel less bulky compared to other large watches, allowing it to sit smoothly on the wrist. The updated 22mm bracelet, slightly wider than the previous version, gives the watch a more stable feel, while the 12.4mm case thickness makes it slim enough to slide under a cuff but still gives it a confident, substantial look.

The Oyster bracelet, crafted from 904L steel, is not only durable but also designed for comfort. The Easylink comfort extension link is a real standout feature, as it allows for a 5mm adjustment without the need for tools – something many users have appreciated during everyday wear or more active pursuits. Whether you’re traveling, out in the field, or just going about your routine, this feature ensures that the watch stays snug and comfortable on your wrist all day long.

From a comfort standpoint, this watch has earned praise for being wearable during long hours of use. In fact, some users mentioned how it’s a pleasure to wear both during intense outdoor activities and in more casual settings without feeling heavy.

Since its debut, the Explorer II has been a reliable companion for those needing precision and durability in extreme conditions. And this version builds on that legacy with thoughtful updates, making it even more practical and suited for everything from rugged outdoor adventures to everyday life.

It is the perfect choice for anyone who values a tough, no-nonsense watch that can handle whatever comes its way, whether you’re exploring the wild or simply navigating the challenges of daily life. This watch is built to endure and perform, day after day, no matter the adventure.
