The Rolex brand is synonymous with precision, durability, and timeless elegance, and within its esteemed lineup, the Rolex Explorer and Rolex Explorer II stand as two of its most iconic timepieces. At first glance, these two Rolex collections may seem like the same watch model due to their remarkable similarities. However, upon closer inspection, the Explorer and Explorer II reveal a series of distinguishing features and functionalities that set them apart.
While both models are inspired by the world of exploration, the original Rolex Explorer, birthed in the 1950s, is a nod to the brand’s association with mountaineering and was linked to Sir Edmund Hillary’s successful ascent of Mount Everest. The Explorer II (1971) was designed explicitly for spelunkers and polar explorers, boasting a 24-hour hand and a fixed bezel, intended to help wearers differentiate between day and night in environments where this distinction isn’t easily discernible.
Both models have evolved over the decades, adapting to the changing needs of explorers and watch enthusiasts alike. Yet, their core difference lies in their distinct functionalities and the specific type of adventurer they are designed to assist. The choice between the two ultimately boils down to individual preferences and the specific challenges one seeks to address.

Rolex Explorer I
History
The Rolex Explorer has a rich history, with its initial release in 1953. Its history is intimately intertwined with daring exploits and adventures that push human limits. Its genesis can be traced back to the highest peak on Earth – Mount Everest. When Sir Edmund Hillary and Tenzing Norgay triumphantly scaled the mountain in 1953, a prototype of the Rolex Explorer, an Oyster Perpetual model, was strapped to Hillary’s wrist, showcasing the brand’s commitment to precision and durability under extreme conditions.
The first Rolex to bear the “Explorer” name was the ref. 6350, introduced in 1953. This was swiftly followed by the ref. 6150 and the renowned ref. 1016, which was introduced in 1960 and remained in production for an impressive 29 years.
The ref. 1016 brought with it the Caliber 1560 movement (later updated to the Caliber 1570), housed within a 36mm case, and sported the emblematic 3, 6, and 9 numerals on the dial.
In 1989, the ref. 14270 was launched, modernizing the Explorer I with a new Caliber 3000 movement and transitioning to a sapphire crystal. The subsequent models, the ref. 114270 and the notable ref. 214270 (which increased the case size to 39mm), continued to innovate in materials and movement technology, while still paying homage to the enduring aesthetic and spirit of the original model.
In 2021, Rolex circled back to tradition with the release of the reference ref. 124270, reviving the classic 36mm size but incorporating the modern Caliber 3230 movement, symbolizing a blend of the Explorer’s rich heritage and contemporary watchmaking advancements. Thus, the Rolex Explorer I, through its various evolutions, continues to be a testament to the brand’s relentless pursuit of excellence and adventure.

Rolex Explorer II
History
The Rolex Explorer II, known for its robust nature and special features for exploration, marked its introduction into the horology world in 1971 with the first Rolex Explorer II model ref. 1655. Initially designed for cave explorers, the original Explorer II featured a distinctive, arrow-shaped 24-hour hand and a fixed, engraved 24-hour bezel to help adventurers differentiate between day and night hours, a crucial function in environments where light is absent.
The ref. 1655 housed the caliber 1575 and became well-known for its unique dial design, which subsequently earned it the nickname “Steve McQueen,” although there is no confirmed evidence that the actor ever wore the model.
In 1985, Rolex introduced the ref. 16550, featuring several changes from its predecessor, including an increased case size of 40mm, a new caliber (3085), and the introduction of a white dial variant. Additionally, the ref. 16550 showcased a sapphire crystal and an independently adjustable hour hand, which could be set without stopping the second hand or altering the minutes and 24-hour hands.
In 1989, the ref. 16570 brought forth the new caliber 3185 (and later 3186) with minor aesthetic changes, sustaining its production for over two decades.
In 2011, to celebrate the 40th anniversary of the Explorer II, Rolex unveiled the ref. 216570, increasing the case size to 42mm and introducing the caliber 3187, which includes the Paraflex shock absorbers and a Parachrom hairspring for enhanced stability and durability.
The most recent iteration as of now, the ref. 226570, was introduced in 2021, maintaining the 42mm case but housing the new generation caliber 3285, demonstrating a substantial improvement in power reserve and precision.
Through its iterations, the Explorer II has steadfastly represented Rolex’s commitment to precision and reliability for those who venture into the world’s most forbidding frontiers.

Investment Potential
The Rolex Explorer II, particularly the ref. 16570, exhibits noteworthy investment potential. It is currently trading at S$10,613 in the private sales market surpassing its retail price, hinting at strong demand and limited availability.
