24 Exquisite Watch Straps for the Rolex Explorer 1 – Reference 214270

What Rolex did Edmund Hillary wear?

In 1953, Sir Edmund Hillary and Sir Tenzing Norgay scaled Mount Everest. That year, Rolex sponsored the expedition and supplied Edmund Hillary with a Rolex Oyster Perpetual Watch. At the time the watch did not bear the Explorer name it’s known by today, in fact, the inspiration for the watch’s name came from that expedition.

Rolex Explorer has a long history of adventure and Rolex isn’t about to disappoint fans of this timepiece.  The Rolex Explorer I reference 214270 was a shift from the earlier 1016 which had a long production period and its successor the 14270.  In 2010, the Explorer I ref 214270 diameter moved from a smallish 36 mm to a larger 39 mm.  The hands were a bit shorter in comparison to the larger case. 

However, the Rolex Explorer I reference 214270 still retained the key features such as 904L stainless steel, the Arabic numerals 3, 6 and 9 at those critical hour markers, and water resistance to 300 feet. It had a flat and polished bezel and a 3-link Oyster bracelet with brushed steel. The bracelet has an Oysterlock clasp with Easylink adjustment mechanism. However, the modern Explorer I is protected by scratch resistant Sapphire crystal.

Rolex Explorer I Caliber 3132

The Calibre 1050 and Calibre 1570 of the earlier generation Explorer references were replaced by the more modern Calibre 3132 in reference 214270. It is an all-Rolex self-winding mechanical movement and certified chronometer featuring a bigger base plate, Parachrom hairspring, and Paraflex shock absorbers. It offers greater resistance to shocks and to extreme conditions. It beats at 28,800vph and contains a power reserve of 48 hours.

The modern size of the Explorer I is beefier than the original Reference 1016 which was produced between 1963 and 1989. The larger size makes it more in line with the typical 40+ mm size of other Oyster Rolex timepieces in the Rolex lineup. It is less a climber’s “tool” and more luxurious, while still retaining the rugged features that brought it to high altitude fame.  It still retains the black dial, polished bezel and powerful steel frame which all types of explorers admire.

Comparing the Rolex Explorer I Mark I (Ref. 214270) and Explorer Mark II (Ref. 214270)

Dials 

The newest Explorer II (Ref. 226570) Dial comes in black or white, whereas the past Explorer I (Ref. 214270) only had a black dial as an option. The Explorer I featured an Arabic numeral dial with 3-6-9 markers. The Explorer II features no numerals, but what is also called a “Maxi Dial”, the circle index markers are also a clear difference. The Explorer II dial is known by Rolex enthusiasts for its clearer readability. 

Bezels

Both Bezels of the Rolex Explorer I 39mm and Explorer II 42mm are made from steel but are visually very different. The Explorer I features a high-polished bezel for a sleeker look and is reflective and shiny. The Explorer II has a satin-finished bezel in texture and stands out dramatically because of its 24-hour GMT tracking embossed onto it; the count-up bezel (also known as a driving bezel) also helps to measure elapsed time. (If damage incurs onto the Explorer II bezel the satin-finish and numbers make it slightly harder to repair– not wanting to damage the numbers).

Lugs

The Explorer II features what is called in the world of horology a “Super case”. Super case means that the lugs of the case are much larger than the Explorer I which has the basic case.  The watch lugs are much thicker in width on the Explorer II and the Explorer II has crown protector lugs as well and the Explorer I does not. 

Movement 

Both watches are automatic. The base caliber of the Explorer I is 3132 and has regular basic timekeeping. The base caliber of the Explorer II is 3285 and features a GMT movement and display date. The Explorer II also has an additional hour hand (the orange hand) that allows you to track another time zone or your own time. 

Glide lock Clasp 

An important addition to the Explorer I version Ref. 214270, is the type of shock absorber, along with a Parachrom hairspring. In addition, a new Oysterlock folding clasp with a satin-finished easy-link extender to adjust the watch bracelet. The Explorer II Ref. 226570 has a slightly broader glide-lock clasp and is polished rather than media-blasted, in texture. This Rolex still features the same 5mm easy-link system (so you can adjust the link measurement without tools). 

Straps – Rolex Explorer I 39mm vs Rolex Explorer II 42mm

Rubber B offers a variety of straps for a variety of watches. For the Rolex Explorer I and Rolex Explorer II all three versions of Classic, Tang buckle, and Cuff Series are offered. For the Explorer I Rubber B also offers a Velcro strap in solid Jet Black to match perfectly with its black dial. Vulcromatic Straps are offered for the Explorer II; the dual-colored straps come in different combinations of black, white, and orange and pair excellently with the iconic orange hand. 

The New Rolex Explorer I 124270 With Caliber 3230

In 2021 Rolex finally addressed multiple issues with the aging Explorer I with the new Reference 124270.  Although it only had been on the market for 10 years, which is a short production period for Explorer, Rolex needed to apply the new enhancements to this timepiece which had been already deployed in other Rolex timepieces.  

Specifically the Caliber 3230 was added to the time honored Explorer 1.  The 3230 expanded the power reserve of the Rolex from 40 hours to an amazing 70 hours.  Rolex also returned to its roots, and reduced the case size of this timepiece back down to the 36mm case size of its early ancestors.  This reduction of size from 39mm to 36mm is one of the few examples of Rolex actually going smaller since the trend has been in the larger direction.  

The new Oystersteel with 904L grade quality replaced the older stainless steel case.  Also, the new Chromalight luminescence is added on all the hour markers and hands.  Small changes include the moving of the name Explorer on the dial from the 6 o’clock position to the 12 o’clock position.
