When you are looking for a watch that you can wear under the toughest conditions, you are probably not looking for a Rolex. However, if you are in the market for one of the toughest luxury watches available, today’s Rolex Explorer 2 review is for you.
After all, it’s a timepiece that’s designed for cave divers and spelunkers. Although not many of you will be using this watch for exploring dark caves, it’s still a watch that’s rich in history.
With that said, let’s take an in-depth look at the Explorer II ref. 216570 a.k.a. the Polar.
Rolex Explorer 2 Review: At a Glance
The Rolex Explorer II is a relatively quirky offering that added plenty of character to the Swiss luxury brand’s stable. Before we go to a detailed Rolex Explorer II review, let’s first check out its key specs and features.

Take note that the 216570 White Dial is the new and improved version of the Rolex Explorer II 16570. There are actually two dial versions of the 216570: white and black (pictured below). While I am a big fan of black dials, I went with the white dial since it somehow looks better than the black version.
My first impression is that the watch maintains most of the essence of classic Rolex timepieces but has been reworked to appeal to contemporary collectors. Perhaps the most obvious change is the 42mm case diameter. In comparison, the original Rolex Explorer 214270 was only 39mm.
It’s one of the largest models in the Rolex catalog.
Purists and traditionalists will surely prefer the smaller 39mm but as an outdoor tool watch, the size increase is more than welcome.
The white maxi dial is another standout with its boldness and superior legibility – perhaps it’s boldest among other Rolex sports watches. The glossy white dial has markers with black surrounds. It is an instantly striking dial with somehow more of the signature Rolex attention to detail.
The construction looks to be on-point and while I’m not too keen on wearing it to explore cave systems, it feels like it would serve me well even if I choose to. It looks and feels like a true tool watch and noticeably less luxurious.
The Polar White Dial
The Polar white dial is a masterclass in contrast. The Chromalight markers and hands sit perfectly against the white background, and the bright orange 24-hour GMT hand adds a perfect contrast to everything that’s going on.
In case you don’t know, the 24-hour hand enables the user to keep the time for two different time zones. In addition, it will also let you know if it’s day or night, very useful when you are down in a cave.
As mentioned, the Rolex Explorer II features top-notch legibility. After all, it’s a watch designed for very low-light environments or at night. Based on my tests, the proprietary Chromalight coating does a great job of providing long-lasting readability.
Plus, it looks amazing when the blue luminescent coating is activated.
The black surround around the oversized markers and stubby hands is another great detail that completes the overall look of the Explorer II. I have always been a fan of the Cyclops lens so it’s a nice cherry on top as far as the dial goes.
The Rolex Explorer 2 is bigger and bolder which is what you want for a heavy-duty tool watch.
The Robust Case
The Rolex Explorer II was first released back in 1971, and since then it has gone through numerous makeovers over the four decades. It was designed for extreme resistance and this is mainly due to its robust case.
Of course, there’s the 904L stainless steel that makes the case which measures 42mm in diameter and a thickness of 13mm. While I don’t have the largest wrist, the 42mm diameter is more preferable to me than the 39mm of the previous Explorer.
Just like with the previous generations of Explorer, the watch is fitted with Rolex’s signature twinlock screw-down crown. This adds a fair bit of waterproofness to the watch and should be able to handle a few splashes. Just make sure you don’t wear the Explorer II for diving.
In classic Rolex style, the watch features sapphire crystal on the front and a solid case back on the back. The 24-hour bezel is made with fixed stainless steel with a satin brush finish. However, the bezel is more prone to scratches. I would have loved it more if it instead had ceramic inserts like on the Rolex Submariner.
However, the brushed finish of the bezel does look great.
The Oystersteel Bracelet
The Explorer II uses the signature Oyster bracelet made in 904L steel with three links. Looking closely, you’ll see that the center links of the bracelet lack polish. This is, of course, a conscious design choice for a more “tool-like” look. However, the sides are polished which adds an interesting twist to the bracelet’s aesthetic.
As you might expect, the bracelet’s construction feels very solid and it comes with the Folding Oysterlock safety clasp with Easylink system. This enables the user to extend or shorten the last link by 5mm increments which is useful for achieving a great fit.
While the Glidelock fine-adjustment extension found on watches like the Submariner is the superior system, the Easylink is useful for adjusting the short and long positions. This allows you to easily adjust the bracelet in case of weather changes.
Of course, you can’t have a Rolex Explorer 2 review without talking about the movement. With that said, the Explorer 2 is powered by the automatic in-house calibre 3187.
The movement features a paramagnetic blue Parachrom hairspring with a 48-hour power reserve. For the price, I was expecting a better power reserve than 48 hours. Having to reset the watch after two days of not wearing it does get old pretty quick.
The blue Parachrom hairspring provides the much-needed resistance against magnetic fields. Plus, it adds a good deal of durability to the watch which is crucial for the type of environments the model is designed for. Even with extreme temperature changes, the Explorer II will remain ticking accurately.
The 3187 won’t blow anyone’s mind when it comes to aesthetic but that’s no big deal since you’re getting a robust solid steel caseback anyway.
Like with all Rolex Perpetual movements, the 3187 is a certified Swiss chronometer with -2/+2 sec/day precision performed after casing.
The Explorer II 216570 Polar is about on the same price range as the Rolex Submariner. However, if you can get a pre-owned Explorer II, expect to pay a little more than a no-date Submariner and a little less than a date Submariner.
It’s no entry-level watch like the Rolex Air-King but it’s certainly an affordable option if you’re looking to get into the Rolex rabbit hole. Due to its not-so-massive popularity, you won’t find an Explorer II that sells for over the retail price. Basically, you can just walk up to a Rolex shop right now and later come out with the watch on hand.
This isn’t the case for other popular Rolex models like the aforementioned Submariner where the cost is driven up by demand.
As far as resale value goes, this luxury steel watch offers a rock-solid resale value. However, it’s not exactly a fly-off-the-shelves sale when compared to other popular Rolex models.
Should You Get the Rolex Explorer II?
To wrap up this Rolex Explorer 2 review, we put in the verdict if this watch is worth the investment or not.
The Explorer II is a somewhat a forgotten model that’s lost in the sea of Submariners, Day-Dates, and Daytonas. This is quite a shame especially when it’s one of the few unashamedly utilitarian Rolex timepieces.
I love the big and bold display with a throwback design to the vintage Explorer. However, Rolex made some excellent updates that make it more appealing for fans of contemporary timepieces. It looks great, especially with the Polar white dial and offers legibility for days. In terms of comfort, the watch sits comfortably on my wrist so I have no complaints.
It’s also perhaps the toughest and most robust Rolex watch that I’ve owned. More than anything, it’s a tool watch and a great one at that.
The Rolex Explorer II is not the kind of watch that I would recommend for first-time Rolex buyers but it sure is an imposing addition to any luxury watch collection.
