ROLEX | Oyster Perpetual Explorer

Oyster Perpetual Explorer

Case Size and Movement Both Upgraded

Text by Yasuto Shibuya

The case size has been increased from the previous model's 36mm, which might feel small today, to an exquisite 39mm. This is the first major appeal of the new Explorer. Another subtle charm is the improved legibility of the dial in darkness, thanks to the use of luminous paint that maintains its bright blue glow for a long time. Of course, the self-winding movement ticking away inside the case has also evolved to the Cal. 3132, which incorporates Rolex's proprietary Paraflex shock absorber and a Parachrom hairspring that is less susceptible to magnetic interference. The craftsmanship of the bracelet with its extension, and its comfort when worn, are also impeccable.

BRAND HISTORY
Founded in the early 20th century, shortly after the wristwatch was invented, Rolex has walked alongside timepieces for over 100 years, achieving remarkable evolution.

The history of Rolex began in 1905 with the establishment of "Wilsdorf and Davis," the brand's predecessor, in London, England. Founder Hans Wilsdorf was a visionary entrepreneur who recognized the potential of the wristwatch in an era when pocket watches were still the norm. In 1907, he moved his operational base to Switzerland to focus on watch manufacturing. The following year, he conceived and registered the brand name "ROLEX."

In 1910, Rolex obtained the first official chronometer certification for a wristwatch, a public accuracy test, attesting to the high precision of its products. In 1926, it invented the "Oyster" case, a fully waterproof and dustproof construction, overcoming the vulnerability of wristwatches constantly exposed to water and dust.

Subsequently, Rolex developed the "Perpetual" self-winding system, which winds the mainspring through the rotation of a rotor, and the "Datejust," which features a digital display at the 3 o'clock position and automatically changes the date at midnight. Rolex's role in the evolution of the wristwatch cannot be overstated.

In the 1950s, the product line diversified, with the creation of watches for professionals undertaking specialized missions, such as the "Submariner," the first diving watch in history, and the "Explorer," a wristwatch for adventurers. Naturally, this focus on creating watches for extreme conditions also enhanced the reliability of Rolex products for general users.

This spirit of ambitious development continues today. In 2000, Rolex achieved in-house production of chronographs. In 2007, it unveiled next-generation models of the "Milgauss" antimagnetic watch and a new chronograph for regattas. While consistently at the center of attention in the watchmaking world, Rolex continues to steadily produce practical timepieces.
