The Rolex Explorer II reference 1655, introduced in 1971, holds a unique place in horological history. While Rolex watches were already renowned for their precision and durability, they hadn't yet achieved the ubiquitous status symbol they are today. This makes the 1655 all the more fascinating, a watch designed with a specific purpose in mind – to equip speleologists and other professionals working in challenging environments with a robust and reliable timekeeping instrument. This article will delve into the heart of the 1655, exploring its movement, its various dial variations, its current market value, and its enduring appeal among collectors.
The Caliber 1570: The Engine of the 1655
At the core of the Rolex Explorer II 1655 lies the caliber 1570, a robust and reliable automatic movement. This movement, a direct descendant of the earlier caliber 1575 used in the GMT-Master, is a testament to Rolex's commitment to mechanical excellence. The 1570 is a workhorse, known for its accuracy, shock resistance, and longevity. Its architecture reflects Rolex's meticulous attention to detail and its dedication to creating a movement that could withstand the rigors of extreme conditions.
Key features of the Caliber 1570 include:
* Automatic Winding: The self-winding mechanism utilizes a rotor to efficiently wind the mainspring, ensuring consistent power reserve without manual intervention. This is crucial for a watch intended for use in environments where winding might be difficult or impractical.
* Hacking Seconds: The seconds hand stops when the crown is pulled out, allowing for precise time setting. This seemingly minor feature is a significant advantage for accurate time synchronization.
* Shock Resistance: The movement incorporates robust shock absorbers to protect the delicate internal components from impacts and vibrations. This is vital for a watch designed for use in demanding situations.
* Robust Construction: The movement is built to exacting tolerances, using high-quality materials and manufacturing processes. This contributes to its exceptional reliability and longevity.
While the 1570 isn't known for elaborate complications, its simplicity is its strength. Its focus is on providing accurate and dependable timekeeping in challenging circumstances, a philosophy that perfectly aligns with the Explorer II's intended purpose. The movement's reliability is a major factor contributing to the 1655's enduring popularity among collectors and enthusiasts. Many examples still function flawlessly decades after their manufacture, a testament to the quality of Rolex's engineering.
