Rolex Explorer II 226570 White Polar Dial: The Underrated 42mm Steel GMT
The Rolex Explorer II reference 226570 with the white polar dial doesn't get the attention of a Submariner or GMT-Master II, and we think that's part of what makes it interesting. It's a 42mm steel sports watch with a true second time zone, a high-contrast dial, and the modern caliber 3285 running underneath. For a daily-wear Rolex tool watch that isn't one of the obvious references, this is one of the better ways in.

Overview
The 226570 is the current-generation Explorer II. It carries the 42mm Oystersteel case, fixed 24-hour engraved bezel, and the independent GMT hour hand that makes this reference a true dual-time watch rather than a styling exercise. The polar configuration pairs the white dial with black outline hands and markers, and the orange GMT hand is the visual signature that ties this reference to the Explorer II lineage.
Case and Wrist Presence
Rolex's official spec sheet lists the case at 12.5mm thick with a 50.1mm lug-to-lug. Our own measurements came in slightly different: 12.8mm thick and 48.5mm lug-to-lug. Either way, the watch wears sporty without feeling oversized. The 42mm case sounds like a lot on paper, but the lug geometry and bracelet taper keep it manageable on most wrists.
The screw-down crown uses Rolex's Twinlock double-seal system, and the watch is rated to 100 meters. It's not a dive watch, but the sealing system is shared with the rest of the professional-line cases and holds up to daily use.
The White Polar Dial
The polar dial is what sets this reference apart from the rest of the sports lineup. Large applied hour markers are filled with blue Chromalight lume, and the hands carry the same treatment. In daylight the contrast reads immediately: black outlines on a bright white base, with the orange GMT hand and the red 24-hour track accents on the bezel. In low light the Chromalight gives off a long blue glow.

The Cyclops lens sits over the date at 3 o'clock, magnifying it the way every modern Rolex date watch does. Against the white dial the date window reads cleanly without disrupting the balance of the face.
Caliber 3285 and GMT Function
The 226570 runs the caliber 3285, the same movement family Rolex uses in the GMT-Master II. Power reserve is approximately 70 hours, the date is instantaneous, and the GMT hour hand is independently adjustable. That matters in practice: the local hour hand jumps in one-hour increments without stopping the seconds, which is how you use a GMT watch when you're changing time zones.
The 24-hour bezel on the Explorer II is fixed, not rotating like the GMT-Master II. That's the functional difference between the two models. With the Explorer II you read a single second time zone off the 24-hour hand; with the GMT-Master you can track a third time zone by rotating the bezel. Both approaches work, they just suit different users.
Bracelet and Clasp
The Oyster bracelet with flat three-piece links is what you'd expect from a modern professional Rolex. The Oysterlock folding clasp is solid and secure, and the Easylink 5mm comfort extension lets you adjust fit on the fly without tools. Wrist size changes throughout the day, and being able to add or remove 5mm in seconds makes the watch more comfortable across temperature swings and activity levels.

Where It Fits in the Rolex Lineup
We think the Explorer II is one of the most underrated watches in the current Rolex catalog. It's a real tool watch with a real complication, but it doesn't carry the waitlist weight of a Submariner or a Daytona. The white polar dial in particular gives this reference a personality that stands apart from the black-dialed GMT-Master II and Submariner lineups.
If you want a Rolex sports watch that doesn't look like what everyone else is wearing, and you actually use a second time zone, the 226570 covers both. It works as a first Rolex, and we see it land just as well with people who already have the obvious references and want something visually different in the rotation.
Frequently Asked Questions
What makes the white polar dial different from other Rolex sports watches?
The polar dial is the only white dial currently offered in Rolex's professional-line sports catalog. The Submariner, GMT-Master II, and Sea-Dweller ship with black dials. The bright white base with black outline hands and markers creates high-contrast legibility and gives the Explorer II its own visual identity in the lineup.
Is the Explorer II 226570 a good alternative to the GMT-Master II?
It depends on how you use the GMT function. The Explorer II has a fixed 24-hour bezel and tracks one second time zone via the orange GMT hand. The GMT-Master II adds a rotating bezel that lets you track a third time zone. Both run caliber 3285-family movements with the same independent hour-hand jump. If you only need two time zones, the Explorer II gets you the same core function without the waitlist pressure on the GMT.
How much does the Rolex Explorer II 226570 cost?
