Rolex Explorer vs Explorer II: Which One Is for You?
They share a name, but the Explorer and Explorer II are very different watches. One is a pared-back three-hander, the other a 42mm GMT with a fixed 24-hour bezel.

The Rolex Explorer vs Explorer II comparison is really a comparison between two different kinds of watch that happen to share a name. The Explorer is one of the simplest watches Rolex makes. The Explorer II is a 42mm GMT with a second time zone and a date. Knowing what each is designed for makes the choice much easier.
A Little History
The Explorer was introduced in 1953, the year of the first successful ascent of Everest, and Rolex has long linked the model to mountaineering and exploration. Its signature is the black dial with large 3, 6 and 9 numerals, designed for quick reading in difficult conditions.
The Explorer II followed in 1971, aimed at explorers working in environments without day and night, such as caves and polar regions. Its 24-hour hand and fixed 24-hour bezel make it possible to tell AM from PM at a glance, and in later generations to track a second time zone.
The Current Explorer: 36mm and 40mm
Rolex currently offers the Explorer in two sizes. The 124270 returned to the classic 36mm diameter in 2021, and the 224270 offers a 40mm alternative. Both use the calibre 3230, a time-only automatic movement with a 70-hour power reserve, and both are water resistant to 100 metres.
The Explorer has no date, no rotating bezel and no extra complications. That simplicity is exactly the point. It is a watch built to tell the time clearly and survive almost anything, and many people see it as the purest expression of what a Rolex sports watch is.
The Current Explorer II: 42mm GMT
The Explorer II, reference 226570, measures 42mm and runs the calibre 3285, the same GMT movement family used in the GMT-Master II, with a 70-hour power reserve. It has a date at 3 o'clock with a Cyclops magnifier, an orange 24-hour hand and a fixed steel bezel engraved with a 24-hour scale. It is also water resistant to 100 metres, and is offered with a white or a black dial.
Because the bezel is fixed, the Explorer II tracks two time zones rather than three. The local hour hand can be jumped forward or back in one-hour steps without stopping the watch, which makes it practical for travel.
Key Differences
- Size: Explorer 36mm or 40mm, Explorer II 42mm.
- Movement: Explorer calibre 3230, time only. Explorer II calibre 3285, GMT with date.
- Functions: the Explorer II adds a date and a second time zone.
- Bezel: smooth bezel on the Explorer, fixed engraved 24-hour bezel on the Explorer II.
- Character: the Explorer is understated and dressy enough for a suit. The Explorer II is larger and more overtly a tool watch.
Who Should Buy the Explorer?
The Explorer suits someone who wants one watch for everything and values restraint. The 36mm version in particular is one of the most versatile watches Rolex makes, equally at home with a T-shirt or a jacket. If you rarely need a date or a second time zone, it is hard to argue against.
Who Should Buy the Explorer II?
The Explorer II suits frequent travellers who want a GMT but prefer something less colourful than a GMT-Master II, and people with larger wrists who find 36mm or 40mm too small. The white "polar" dial is one of the most distinctive sports dials Rolex offers.
Availability
Both models have historically been easier to obtain at retail than a Submariner or GMT-Master II, though demand for all Rolex steel sports watches remains high. It is worth asking an authorised dealer directly before assuming either is unavailable.
The Bottom Line
I think the Explorer is the better everyday watch and the Explorer II is the better tool. If you can only have one and do not travel across time zones often, the Explorer's simplicity is its greatest strength. If you do, the Explorer II earns its extra size.
