Rolex Explorer II 16570 Review

THE FIRST LOOK

Rolex Explorer II 16570 First Impressions

What hits you the moment you pick up the 16570.

Pick up the Rolex Explorer II 16570 after handling its chunky modern replacement and the first thing that registers is restraint. Among Rolex watches this is the quiet one, a fully brushed steel sports watch with no ceramic bezel, no flash, and none of the immediate recognition a Submariner or a Datejust pulls in a room. It reads first as a tool, then as a Rolex. That is exactly the appeal for the people who seek it out.

The proportions are the headline. At 40mm with relatively short lugs and a slim profile, the 16570 sits flat and balanced, nothing like the slab-sided 42mm cases that came after it. The fixed 24-hour bezel and the thin red 24-hour hand give the dial a busy, purposeful look up close, but at arm's length the watch is calm and legible. Whether you reach for the black dial or the white Polar, the impression is the same: this is a watch built to be used and ignored, not admired in a display case.

THE WEARING EXPERIENCE

On the Wrist

How the 16570 actually wears, day in and day out.

The Rolex Explorer II 16570 is one of the easiest steel sports watches Rolex ever made to live with. The 40mm case carries a listed thickness of roughly 12.2mm, but the short lugs and flat caseback are what really matter on the wrist. It tucks under a shirt cuff without snagging and settles onto wrists from about 6.5 inches up without the lugs overhanging. If you have tried a 42mm 216570 and found it top-heavy or oversized, the 16570 is the antidote.

Weight is moderate and well balanced, helped by the all-steel construction and the tapering Oyster bracelet. Earlier examples with hollow end links rattle slightly and feel a touch looser, while the later solid end link versions sit tighter and more planted. Day to day, the 16570 is the rare luxury watch you can genuinely forget you are wearing, which is the highest compliment a tool watch earns. The black dial disappears into a sleeve and reads as a generic steel watch to outsiders, while the Polar stands out just enough to draw a second look from anyone who knows.

BUILD QUALITY

Rolex Explorer II 16570 Specifications

Breaking down the case, dial, bezel, and bracelet from every angle.

Case

The Rolex Explorer II 16570 case is a 40mm stainless steel Oyster with brushed tops and polished sides, a screw-down Twinlock crown flanked by crown guards, and 100m of water resistance. It was the first Explorer II to get a sapphire crystal, replacing the acrylic of the earlier 16550, and the last to use a 40mm diameter before the 42mm Maxi case arrived in 2011. One detail collectors track closely: examples made before roughly 2000 have drilled lug holes, while later cases switched to the cleaner no-holes look. Neither is better, but it changes the character and affects how easily you can swap the bracelet.

Dial and Bezel

The Rolex Explorer II 16570 dial comes in two flavors only, black or white Polar, and the bezel is the same on both: a fixed, engraved 24-hour steel bezel that pairs with the independent red 24-hour hand to track a second time zone. The Polar dial is the visual signature of the reference, with black surrounds outlining the hands and markers, a treatment that is unique among 40mm steel Rolex sports watches. The black dial uses white gold surrounds instead and reads more like a stealthy generic tool watch. Lume evolved over the run, from tritium on early pieces (marked SWISS T < 25), to LumiNova around 1998, to SuperLumiNova from 2000 onward, and the very late examples added the laser-etched rehaut engraving around the dial edge.

Bracelet

The Rolex Explorer II 16570 wears on a fully brushed steel Oyster bracelet with a stamped, folding clasp, the last Explorer II to use that older clasp design. Early examples have hollow end links, which can feel slightly loose and contribute to perceived bracelet stretch over decades of wear, while examples from around 2000 onward use solid end links that sit tighter and feel more substantial. There is no modern micro-adjustment system here, so dialing in a perfect fit means sizing links carefully. For a watch of this era it is comfortable and durable, if not as refined as a current Oyster bracelet.

EXPERT TIP | Robertino Altieri | WatchGuys CEO

What to Check on a Pre-Owned 16570

"On a 16570 I always check three things first. Look hard at the bracelet for stretch, because these have a stamped clasp and hollow end links on the earlier ones, and a stretched bracelet is the most common flaw. Confirm the lume type matches the serial year, tritium, LumiNova, or SuperLumiNova, since refinished dials show up here. And if it is a later piece, make sure the rehaut engraving is crisp and correctly aligned. Box and papers help, but on a watch this age, originality of the dial and bezel matters more than the paperwork."

UNDER THE HOOD

Rolex Explorer II 16570 Movement Review

How the movement performs where it matters: on the wrist, every day.

The Rolex Explorer II 16570 runs the automatic Caliber 3185 from 1989 until roughly 2007, when Rolex replaced it with the Caliber 3186. Both beat at 28,800 vph, both are COSC chronometer certified, and both are built on the legendary 3135 architecture with an added independent 24-hour hand. In practice that means a watch you can set, wear, and trust to keep excellent time, typically within a few seconds a day on a healthy, recently serviced example. The headline difference is the 3186's blue Parachrom hairspring, which adds antimagnetic and temperature resistance and quietly fixed the slight wobble the 3185's 24-hour hand exhibited when setting.

In daily use the practical quirk is that neither caliber has a quickset date. To advance the date you jump the main hour hand forward in one-hour steps with the crown, which doubles as the way you set a second time zone. It sounds clumsy on paper and is genuinely intuitive in the hand within a day. The 24-hour hand, set independently, tracks home time while the main hands follow local time, exactly what a dual-time watch should do. Power reserve runs about 48 hours on the 3185 and 50 on the 3186, so a watch left off the wrist over a weekend will usually stop, which is the only real ownership compromise. Service from Rolex or a qualified independent runs in the several-hundred to roughly one-thousand-dollar range depending on the watchmaker and what the movement needs, and these calibers are about as serviceable and robust as mechanical watches get.

EXPERT TIP | Robertino Altieri | WatchGuys CEO

3185 or 3186: Do Not Overpay for the Movement

"People obsess over 3185 versus 3186 and overpay for the later caliber. Here is the truth from selling both: in normal wear you will never feel the difference. The 3186 has the Parachrom hairspring and a steadier 24-hour hand, which is nice, but the 3185 is a fantastic movement. I tell buyers to chase condition and a clean service history first. A freshly serviced 3185 in a sharp case beats a tired 3186 every single time."

MARKET VALUE

Current Market Snapshot

What the 16570 costs right now on the secondary market.

The Rolex Explorer II 16570 remains one of the most reasonably priced ways into a steel professional Rolex. Clean pre-owned examples generally trade from the mid $7,000s for an honest, well-worn black dial up to around $12,000 for a mint, complete, late-production Polar with solid end links and the engraved rehaut. The long 22-year production run means supply is healthy and there is a watch at almost every budget and condition level, which keeps pricing rational rather than hype-driven.

On trend, the 16570 has been broadly stable to slightly soft over the past year and is down modestly over five years, in line with the wider Rolex sports market cooling from its peak. For a buyer that is good news: this is a watch you buy to wear, not to flip, and it sells quickly when you are ready to move on because demand for a sensible 40mm steel Rolex never really goes away. Value drivers within the reference are condition, dial choice (Polar carries a premium over black), solid versus hollow end links, original unrefinished dial, and a complete set.

HEAD TO HEAD

How It Compares

The 16570 against the alternatives buyers actually cross-shop.

Rolex Explorer II 16570 vs. Rolex Explorer II 216570 (Successor)

The most common cross-shop is the 16570 against its direct successor. The 216570 grew the case to a 42mm Maxi case, enlarged the dial, hands, and lume for better legibility, and added the Easylink comfort extension and an updated movement. It is the more capable, more legible, more modern watch. But it also wears noticeably bigger and heavier, and it loses the discreet, neo-vintage charm that draws people to the 16570 in the first place. If you want the most usable Explorer II, look at the 216570. If you want the most wearable and characterful one, the 16570 wins.

Robertino's Take

"I have sold plenty of both, and the 16570 is the one I steer most buyers toward. The 40mm case is just more wearable for more people, and the price is friendlier. The 216570 is a great watch, but the jump to 42mm changes the whole feel. If your wrist is medium or smaller, the 16570 is the smarter buy, full stop."

Rolex Explorer II 16570 vs. Rolex GMT-Master II 16710 (Sibling)

For most of their lives the Explorer II 16570 and the Rolex GMT-Master II 16710 shared the very same movement and a 40mm case, so the real decision is about function and looks. The GMT-Master II 16710 has a rotating, bidirectional 24-hour bezel that lets you track a third time zone and comes in colorful Pepsi and Coke configurations, making it the more versatile traveler and the flashier watch. The 16570's fixed bezel tracks two zones only and keeps everything monochrome steel. If you travel across many time zones and want a pop of color, the GMT wins. If you want something cleaner, quieter, and usually a bit cheaper, the Explorer II is the pick.

THE BOTTOM LINE

The Verdict

Is the 16570 worth your money?

Yes, the Rolex Explorer II 16570 is worth buying, and for a lot of people it is the single smartest entry into a steel professional Rolex. It nails the things that matter most in a daily watch: a genuinely wearable 40mm case, faultless legibility, a useful dual-time function, and a movement that will run for decades with basic care. That it costs meaningfully less than a Submariner or a GMT-Master only sweetens the case.

This watch is perfect for the buyer who wants one steel Rolex sports watch to wear every day without thinking about it, especially anyone with a medium or smaller wrist who finds modern 42mm cases too much. It is also ideal for the value-minded buyer who would rather own a fully sorted neo-vintage piece than stretch for the latest reference. Who should look elsewhere? If you need a rotating GMT bezel for frequent travel, the GMT-Master II makes more sense, and if you want the brightest lume and the most modern build, the larger 216570 or 226570 will serve you better. The single strongest reason to buy the 16570 is simple: it is one of the most honest, wearable, and fairly priced watches Rolex has ever made.

Robertino's Take

"The 16570 is the one I recommend when someone wants a real steel Rolex without overpaying or overthinking it. Buy the best condition example you can find, prioritize an original dial and a tight bracelet, and do not lose sleep over 3185 versus 3186. This is a forever watch. Wear it, hand it down, and it will still be desirable long after the hype watches have cooled off."
