Rolex Explorer 214270 Mark 1 (2010–2016), 39mm steel Oyster, photographed on its Rolex presentation box with the guarantee card visible. Christie's, Watches Online: Time – Autumn, 2016.

The 214270 is the 39mm Explorer generation. In 2010 Rolex took the case from 36mm to 39mm, the first size change in over 57 years; the Explorer had run at 36mm since the 6610 in 1953. The larger case and the first dial configuration drew criticism in contemporary reviews; the later dial revision changed the hands and the 3-6-9 numerals.

Two versions exist within this reference number. The Mark 1 (2010-2016) drew criticism for short hands and unluminous 3-6-9 numerals. The Mark 2 (2016-2021) corrected both. In 2021, the 124270 replaced the 214270 and returned the Explorer to 36mm. The reason for the 124270's return to 36mm is not stated in the cited sources.

Where it sits in the line

The 214270 follows the 114270 and precedes the 124270. It is the only 39mm Explorer reference, with 36mm references on either side.

The 214270 appeared as Rolex was using larger cases elsewhere in its catalogue. Contemporary reviews compared its proportions and wrist fit with the 36mm 114270.

The 124270 returned the line to 36mm in 2021. The 214270 remains a distinct 39mm reference; preference and demand are separate market questions.

Production outline

The reference has two documented dial versions and uses calibre 3132 throughout its run.

Mark 1 (2010–2016) is the launch specification: 39mm case with caliber 3132, uncoated white gold 3-6-9 numerals without luminous fill, and hands that were criticized for being too short to reach the minute track. The hour markers and hands carried Rolex's blue Chromalight, but the white gold 3-6-9 numerals were left bare. The Explorer model name moved to the 6 o'clock position on the dial.

Mark 2 (2016–2021) retains the same case and movement but uses longer hands and luminous-filled 3-6-9 numerals. The cited sources describe this as the first luminous Explorer 3-6-9 treatment since reference 1016. The existing Chromalight on the markers and hands was also applied to the numerals.

From July 2015, production examples received Rolex's Superlative Chronometer certification, guaranteeing +/-2 seconds per day accuracy, tighter than the standard COSC specification. This applies to late Mark 1 and all Mark 2 examples.

Movement notes

Caliber 3132 is the 114270 movement plus Paraflex and Parachrom-era refinement. The 3132 runs at 28,800 vph with about 48 hours of power reserve, COSC chronometer certified throughout.

The movement was also used in other Rolex references of the period. The cited sources do not establish a special 214270-only movement configuration.

Dial map

The 214270 has two clearly defined dial versions, with different hand and numeral treatments.

Mark 1 (2010-2016)

Contemporary reviews criticized the Mark 1 because its 3-6-9 numerals were not luminous and its hands appeared short against the 39mm dial.

The short hands and non-luminous numerals were the main points raised in contemporary criticism. The hands that had worked at 36mm did not scale to 39mm. Whether Rolex reused the 114270 hands or drew new ones that were still too short has never been documented.

Mark 2 (2016-2021)

The 3-6-9 numerals are filled with luminous material, the first Explorer since reference 1016 to carry luminous numerals in that layout. The 1016 used painted luminous numerals; the 2016 dial uses luminous-filled white-gold numerals. James Stacey, reviewing the launch for aBlogtoWatch in 2016, pointed out that the hands and markers already glowed Chromalight and that the update only brought the numerals into the lume. In low light the whole dial now reads: indices, numerals, and hands together.

The hands are longer and wider. The minute hand reaches the minute track, and the hour hand is wider than on the Mark 1. The blue Chromalight is otherwise unchanged from the Mark 1, and the Explorer text stays at 6 o'clock.

The Mark 2 brings luminous 3-6-9 numerals and longer hands to the 39mm case. Preference between the two versions is subjective.

Case, bezel, crystal, and crown

The case is a 39mm Oyster in Oystersteel. Compared with the 36mm 114270, the larger diameter changes the watch's proportions and wrist fit; the effect depends on the wearer and strap or bracelet fit.

The case has brushed lug tops and polished sides.

The crystal is flat sapphire, and with no date window there is no Cyclops. The crown uses Rolex's Twinlock system, and the watch is rated to 100m. The bezel is polished steel, unmarked and fixed.

Bracelets, end links, and clasps

Oyster bracelet with solid end links throughout both Mark 1 and Mark 2 production. The exact bracelet reference number is not confirmed. The clasp is an Oysterlock type with Easylink comfort extension.

The bracelet architecture is shared with the 114270. The exact bracelet reference is not confirmed in the cited sources.

Mark 1 collectibility

Collectors use “Mark 1” and “Mark 2” to separate the two documented dial and hand configurations. The Mark 1 has the unfilled 3-6-9 numerals and shorter hands; the Mark 2 has luminous numerals and longer hands. The cited sources do not establish production totals or a reference-wide market premium for either version.

The size debate

Contemporary reviews described the 39mm case as giving the dial more presence and legibility. Other reviews preferred the compact proportions of the 36mm references. At 39mm, the 214270 has a larger visual footprint than the 114270 and 124270.

Rolex returned the Explorer to 36mm with the 124270 in 2021. The 214270 remains the only 39mm Explorer reference. The cited sources do not state why Rolex returned to 36mm.
