Rolex · Family: Explorer
The Rolex Explorer 124270 is the current 36mm execution of the brand's oldest exploration watch, relaunched in 2021 with the in-house Calibre 3230 and roughly 70 hours of power reserve. Cazador has no verified price observations as of July 2026; we do not estimate a range without our own PricePoints. Its differential: it's the only current Rolex professional model with no date or Cyclops lens, carrying the black dial and 3-6-9 numerals traced back to the 1953 Everest expedition.

The Explorer family traces back to 1953, when Rolex accompanied the first documented ascent of Mount Everest, led by Sir Edmund Hillary and Tenzing Norgay, with the brand's watches among the expedition team's equipment. That same year, Rolex introduced the Oyster Perpetual Explorer reference, with a black dial and the now-signature Arabic 3, 6, 9 numerals over triangular indices — a design built for maximum legibility in extreme conditions that still defines the entire family seven decades later.
For much of its recent history the Explorer sat in a 36mm case, until Rolex introduced the 214270 in 2010 at 39mm — a decision that sparked an enduring debate among collectors over which size stayed truer to the model's original spirit.
In 2021, marking the 70th anniversary of the first Everest ascent, Rolex relaunched the Explorer at 36mm under reference 124270, restoring the family's historic proportions alongside a parallel refresh of the Explorer II (reference 226570). The size change came with a full mechanical update.
Inside sits the in-house Calibre 3230, built around the Chronergy escapement and a blue Parachrom hairspring, delivering roughly 70 hours of power reserve and Superlative Chronometer certification — Rolex's own standard, more demanding than a standard COSC certification, applied to the fully cased watch rather than the bare movement alone.
Unlike other Rolex professional models, the Explorer 124270 deliberately skips a date function and, with it, the Cyclops lens on the crystal — a design choice that reinforces its character as a pure instrument watch, focused on hour-and-minute legibility over any added complication. The Oyster bracelet carries the Easylink extension system, adding roughly 5mm of slack without tools. As of this writing, the Explorer 124270 remains in Rolex's current, active catalog.
The 124270 brought back the historic 36mm diameter in 2021, versus the 39mm of the 214270 launched in 2010. It also introduced the in-house Calibre 3230, with the Chronergy escapement and Superlative Chronometer certification.
Cazador has no verified price observations for this reference yet. We do not estimate or invent a figure without our own PricePoints; this section activates once sufficient data exists.
It's a design choice inherited from the original 1953 model: the Explorer prioritizes hour-and-minute legibility as a pure instrument watch, without the date complication or Cyclops lens found on other Rolex professional models.
It's the original 1953 design, built for maximum legibility in extreme conditions like the Everest expedition. Rolex has kept it largely unchanged on the Explorer dial ever since.
Approximately 70 hours, thanks to the Chronergy escapement and blue Parachrom hairspring, both developed in-house by Rolex to improve the movement's energy efficiency.
No. They are separate families within Rolex's catalog: the Explorer 124270 measures 36mm with no date or second time zone, while the Explorer II (226570) measures 42mm and includes a GMT hand and date.
Per the catalog data we work from, the reference remains in active production. This fiche will update as soon as any change of status is confirmed.
