The Rolex Submariner, a name synonymous with diving prowess and enduring style, holds a special place in horological history. While the model's iconic design solidified in the post-war era, the 1970s represent a fascinating chapter in its evolution, marked by subtle yet significant changes in design, materials, and the ever-evolving quest for chronometric accuracy. This article delves into the world of 1970s Rolex Submariners, specifically focusing on the "Superlative Chronometer" designation, and explores the broader context of Rolex chronometer history and the wider landscape of 1970s Rolex production. We will also touch upon related models and the factors influencing the prices of these vintage timepieces today.
Rolex Chronometer History: A Legacy of Precision
Before diving into the specifics of the 1970s Submariner, it's crucial to understand the historical context of Rolex's commitment to chronometric excellence. Rolex's journey towards becoming a leading chronometer manufacturer began early in the 20th century. The company's relentless pursuit of accuracy led to rigorous internal testing and the development of highly precise movements. This dedication culminated in Rolex's watches receiving official chronometer certification from COSC (Contrôle Officiel Suisse des Chronomètres), an independent Swiss body that rigorously tests watches for accuracy and precision. Gaining COSC certification wasn't merely a marketing ploy; it represented a tangible demonstration of Rolex's unwavering commitment to quality and accuracy.
The early decades of Rolex's history saw the development of various movements and models that gradually incorporated and refined the chronometer certification process. The Oyster case, with its water-resistant design, played a crucial role in protecting the delicate movements and ensuring reliable performance in challenging environments. This combination of robust construction and precise movements laid the foundation for the iconic Submariner and other professional watches that followed.
Rolex Chronometer: The Hallmark of Accuracy
The "Chronometer" designation on a Rolex watch is not just a label; it's a testament to its exceptional timekeeping capabilities. A watch earns the title of "chronometer" only after passing the stringent tests conducted by COSC. These tests involve subjecting the movement to various positions and temperatures to assess its accuracy and stability over time. Only watches that meet the exacting COSC standards receive the coveted certification.
In the 1970s, Rolex's dedication to chronometric precision intensified. The Superlative Chronometer certification, while not yet the formal designation we know today, represented Rolex's internal commitment to exceeding even the already high COSC standards. This implied a level of accuracy and reliability that went beyond the official certification, reflecting Rolex's ongoing pursuit of perfection.
