Reference:224270
Explorer → 224270
The 224270 is Rolex’s answer to a question the 124270 left open: what about collectors who liked wearing a larger Explorer? When the Explorer went back to 36mm in 2021, it was a homecoming for the faithful – but it also orphaned everyone who had been perfectly happy with the 39mm 214270’s wrist presence. Two years later, at Watches & Wonders 2023, Rolex introduced the 224270 at 40mm. Not a replacement for the 36mm. A companion.

Where it sits in the line
The current Explorer lineup has two sizes: 36mm (124270) and 40mm (224270). This is new territory for the Explorer. Before 2023, Rolex always offered a single case size – 36mm for decades, then 39mm from 2010 to 2021, then back to 36mm. The 224270 makes the Explorer a two-size family for the first time.
The 224270 effectively fills the niche left by the discontinued 39mm 214270. Collectors who preferred that watch’s larger proportions now have a proper current-production option – slightly bigger, in fact, at 40mm versus 39mm. The 214270’s role in the lineup has been formally replaced, even if the 224270 is not a direct successor in the reference-number lineage.
Production outline
A current-production reference introduced at Watches & Wonders 2023. Single configuration: Oystersteel, black dial. No Rolesor variant has been announced (unlike the 36mm 124270, which has the two-tone 124273).
The introduction was less dramatic than the 124270 two years earlier. No size controversy, no two-tone surprise. This was Rolex completing the lineup – giving the Explorer the same size-option strategy that the Datejust and Day-Date have employed for years.
Movement notes
Caliber 3230, identical to the movement in the 36mm 124270 and the Submariner 124060. The 70-hour power reserve is the headline specification, up from 48 hours in older Explorer movements.
The technical platform: 31 jewels, 28,800 vph, Chronergy escapement with nickel-phosphorus components (paramagnetic), blue Parachrom hairspring (also paramagnetic, shock-resistant). The escape wheel is skeletonized for energy efficiency.
COSC-certified, then further tested to the Rolex Superlative Chronometer standard: -2/+2 seconds per day after casing. The same movement, the same performance guarantee, regardless of whether it sits in the 36mm or 40mm case.
Dial map
One dial configuration. Black lacquer with a glossy finish, 18k white gold 3-6-9 numerals filled with Chromalight. Mercedes-style hands in 18k white gold with Chromalight, wider than the 124270’s hands to suit the larger dial diameter.
A detail collectors will notice: the “Explorer” text sits at 12 o’clock on the 224270. The discontinued 214270 had it at 6 o’clock. This is a reversion to the traditional Explorer layout and aligns the 224270 with the 124270’s dial architecture.
Case, bezel, crystal, and crown
The 40mm Oystersteel case is a monobloc middle construction. The finishing is mixed: brushed top surfaces with polished sides and a polished bezel. This gives the watch a slightly more refined look than a fully brushed tool watch, though the overall character remains firmly Explorer.
Dimensions: 40mm diameter, 11.6mm thickness, approximately 46.5mm lug-to-lug, 21mm lug width tapering to 19mm at the clasp. The lug-to-lug is modest for a 40mm watch, which keeps the wearing experience reasonable on smaller wrists. The 21mm lug width is wider than the 124270’s 20mm, which gives the bracelet a slightly more substantial feel.
The sapphire crystal has anti-reflective coating. The Twinlock screw-down crown provides 100 metres of water resistance. The caseback is solid steel, screw-down.
Bracelets, end links, and clasps
Three-link Oyster bracelet in brushed Oystersteel with polished edges on the center links. Oysterlock safety clasp with Easylink 5mm comfort extension. The bracelet is 21mm at the lugs, consistent with the wider case proportions.
The finishing treatment on the bracelet – brushed with polished edges – gives the 224270 a slightly more dressed-up feel than a fully brushed Oyster bracelet. This is the Explorer acknowledging that it lives on wrists in offices as much as outdoors.
Key differences from the 124270
For collectors choosing between the two current Explorers, the practical differences are:
| specification | 124270 | 224270 |
|---|---|---|
| diameter | 36mm | 40mm |
| lug width | 20mm | 21mm |
| hand/marker width | standard | wider (proportional) |
| price (EUR) | ~6,100 | 7,550 |
| Rolesor option | yes (124273) | no (as of 2023) |
The movement is identical. The dial layout is identical. The difference is size, proportion, and price. If you wore the old 39mm 214270 happily, the 40mm 224270 is your watch. If you always thought the Explorer should be 36mm, the 124270 is waiting.
