One Name, Two Completely Different Watches
The Rolex Explorer I and Explorer II share a name and a heritage — both trace back to Rolex’s partnership with Himalayan expeditions in the 1950s. But they’re fundamentally different watches for different people. The Explorer I is a minimalist three-hand time-only watch with the iconic 3-6-9 dial. The Explorer II is a GMT-equipped expedition watch with a fixed 24-hour bezel and date complication. Choosing between them isn’t a matter of “better” — it’s a matter of what you need your watch to do.
History
Explorer I: Born on Everest (1953)
The Explorer I (Ref. 6350) was introduced in 1953 following the successful first summit of Mount Everest by Edmund Hillary and Tenzing Norgay on May 29, 1953. Whether Hillary wore a Rolex to the summit is debated (he likely wore a Smiths) but Rolex’s association with the expedition — equipping the entire team — created the Explorer legend.
The original design was simple: 36mm Oyster case, black dial, 3-6-9 Arabic numeral indices with luminous paint, Mercedes hands, and nothing else. No date, no complications, no frills. It was designed for one purpose: to tell the time accurately in extreme conditions.
Explorer II: Born Underground (1971)
The Explorer II (Ref. 1655) was designed for speleologists (cave explorers) and polar researchers who spend extended periods without natural light. The fixed 24-hour bezel with an additional orange 24-hour hand allows the wearer to distinguish AM from PM — critical when you’re underground for days or experiencing polar midnight sun. The “Steve McQueen” nickname is apocryphal — McQueen never wore one — but it stuck.

The Case for the Explorer I
At 36mm, the Explorer I is Rolex’s smallest current sports watch — and for many collectors, that’s its greatest strength. In an era of oversized watches, the 124270 is a deliberate rejection of size creep. It sits flat on the wrist, disappears under a cuff, and goes everywhere without drawing attention.
The 3-6-9 dial is one of the most legible watch faces ever designed. There’s no date to distract, no bezel to fidget with, no complications to set. Just hours, minutes, seconds, and luminous markers that glow all night. It’s the watch equivalent of a perfectly tailored white shirt: impossibly simple, impossibly correct.
The Explorer I appeals to minimalists, small-wrist wearers, vintage enthusiasts (it’s the closest current Rolex to a 1950s design), and anyone who believes the best watch is the one you forget you’re wearing.
The Case for the Explorer II
The Explorer II is the functional choice. The 42mm case provides a larger, easier-to-read dial. The GMT complication lets you track a second time zone — genuinely useful for travelers, and a feature the Explorer I lacks. The fixed 24-hour bezel allows AM/PM distinction in environments without daylight. And the date window, while purists may grumble, is practical for daily wear.
The white “Polar” dial Explorer II (226570) is one of Rolex’s most distinctive current designs — the combination of white dial, orange GMT hand, and steel case creates a look that’s sporty, readable, and unlike anything else in the lineup. It’s become a cult favorite since the 2021 redesign.
Which One Holds Value Better?
Both are strong performers:
- Explorer I 124270: Trades at $9,000-$11,000 (22-50% over $7,350 retail)
- Explorer II 226570 Black: Trades at $11,500-$13,000 (20-36% over $9,550 retail)
- Explorer II 226570 Polar: Trades at $12,500-$14,000 (31-47% over retail) — the white dial commands a premium
The Explorer I has a slight edge in percentage premium over retail, driven by its cult status among minimalist collectors and its historical connection to the Everest expedition.
Frequently Asked Questions
Is 36mm too small for a men’s watch?
No. 36mm was the standard men’s watch size from the 1920s through the 1990s. The current trend toward 40mm+ is historically unusual. If your wrist is 6-7 inches, 36mm is proportionally correct. Above 7.5 inches, you may find it small. Try it on — most people are surprised how “right” 36mm looks.
Can the Explorer II work as a GMT like the GMT-Master?
Yes — the Cal. 3285 includes a quickset local hour hand, identical to the GMT-Master II. The only functional difference is that the Explorer II’s bezel is fixed (you can’t rotate it to track a third time zone), while the GMT-Master’s bezel rotates. For two time zones, both work identically.
Why doesn’t the Explorer I have a date?
Purism. The original 1953 Explorer had no date, and Rolex chose to maintain that simplicity. For collectors, the absence of a date window is a feature, not a missing specification — it keeps the dial symmetrical and clean.
Do you carry Explorer superclones?
Yes — our Explorer collection at DR.WATCH includes both Explorer I and Explorer II references with Swiss automatic movements, Chromalight-spec lume, and 904L Oystersteel cases. The Polar dial Explorer II is particularly popular. Free worldwide shipping + 1-year warranty.
