The Rolex Submariner reference 1680 holds a special place in the hearts of collectors. Unlike its no-date siblings, which saw incremental movement upgrades throughout their production runs, the 1680, with its iconic date complication, remained steadfast in its use of a single, albeit highly refined, movement: the Caliber 1570. This consistency, coupled with its distinctive design features, contributes significantly to the watch's enduring appeal and high value in the vintage market. Understanding the Caliber 1570 is crucial to appreciating the 1680's legacy and its current position within the world of collectible timepieces.
The Caliber 1570, a self-winding automatic movement, is the defining mechanical heart of the Rolex Submariner 1680. Introduced in the late 1960s, it represents a significant step forward in Rolex's horological evolution. While sharing a lineage with earlier movements, the 1570 incorporated several key improvements that enhanced its reliability, accuracy, and overall performance. These advancements cemented its reputation as a robust and dependable mechanism, perfectly suited to the rigors of underwater exploration and daily wear.
One of the most notable features of the Caliber 1570 is its robust construction. Built to withstand the pressures of deep-sea diving, the movement boasts a high level of shock resistance and water resistance, mirroring the overall ruggedness of the Submariner case. This durability is a testament to Rolex's commitment to producing timepieces capable of withstanding extreme conditions. The movement's components are meticulously crafted from high-quality materials, ensuring longevity and precision. The meticulous finishing, characteristic of Rolex movements, contributes to both the aesthetic appeal and the functional efficiency of the Caliber 1570.
The movement's self-winding mechanism, powered by a rotor, is another key element contributing to its practicality. This eliminates the need for manual winding, providing continuous power reserve as long as the watch is worn. The automatic winding system ensures consistent timekeeping, even during extended periods of inactivity. The power reserve, typically around 48 hours, allows for convenient removal and re-wearing of the watch without the need for immediate resetting.
While not as visually prominent as the dial or bezel, the Caliber 1570's impact on the overall performance and value of the Rolex Submariner 1680 is undeniable. Its reliability and accuracy are frequently cited by collectors as key factors in their appreciation of the watch. The movement’s inherent robustness has ensured that many examples continue to function flawlessly decades after their manufacture, a testament to Rolex’s engineering prowess and the quality of the materials used.
Beyond its technical specifications, the Caliber 1570 is intrinsically linked to the history and heritage of the Rolex Submariner 1680. The movement's presence within the watch adds to its authenticity and desirability among collectors. The consistent use of the 1570 throughout the 1680's production run emphasizes the watch's design integrity and the brand's commitment to a proven and reliable mechanism. This contrasts with the iterative movement changes seen in other Submariner models, making the 1680 a uniquely consistent and desirable piece for enthusiasts seeking a specific historical period.
