The Rolex Explorer II reference 1655. The name itself conjures images of daring expeditions, perilous descents into the earth's depths, and the unwavering reliability of a tool watch designed to withstand the harshest conditions. This iconic timepiece, introduced in 1971, holds a special place in the hearts of collectors and enthusiasts alike, representing a unique chapter in Rolex's history and a testament to the brand's commitment to innovation and rugged durability. Unlike its GMT-Master counterpart of the era, the 1655 wasn't designed for global travelers; its purpose was far more specific, and its design reflects this singular focus.
This article will explore the fascinating world of the Rolex Explorer II reference 1655, delving into its technical specifications, the variations in its dial, its historical significance, its current market value, and the enduring appeal that continues to make it a highly sought-after collector's piece.
The Heart of the Beast: Caliber 1575
At the heart of the Explorer II reference 1655 beats the robust caliber 1575 movement. This automatic, self-winding mechanism shared its lineage with the then-current GMT-Master reference 1675, inheriting its key feature: the independent 24-hour hand. This hand, crucial for the watch's intended purpose, allows wearers to easily distinguish between AM and PM, even in conditions of complete darkness. This is a critical feature for cave explorers navigating subterranean labyrinths where the natural light cycle is irrelevant. While the GMT-Master utilized a rotating bezel to track a second time zone, the Explorer II reference 1655 opted for a fixed 24-hour bezel. This fixed bezel, with its clearly marked 24-hour scale, provided a straightforward and robust method for telling time in environments where a rotating bezel might be prone to accidental adjustments or damage. Cave explorers only need to know the time of day, not a second time zone, hence the simpler, more rugged design.
The caliber 1575, known for its reliability and accuracy, is a significant part of the 1655's enduring appeal. Its robust construction ensured that the watch could withstand the shocks and vibrations encountered during extreme activities, making it the perfect companion for spelunking expeditions. Its relatively simple design, compared to later movements, also contributed to its ease of servicing and maintenance, a crucial factor for a watch intended for demanding use.
Rolex 1655 Dial Variations: A Collector's Delight
The dial is where the true character of the 1655 shines through. The variations found across different examples are a significant factor in determining their value and collectibility. While the overall design remains consistent—a clean, legible layout with luminous hour markers and hands—subtle differences exist that captivate collectors. These variations include:
* Marker Styles: The hour markers themselves varied, with some models featuring painted markers, while others boast tritium-filled markers. The shape and size of these markers can also vary subtly, adding to the individuality of each piece. The luminescence, initially tritium, has aged differently in different watches, creating a unique patina that is highly sought after by collectors.
