The Rolex Submariner reference 1680 holds a unique place in the history of the brand and within the hearts of collectors. Produced from 1966 to 1979, this transitional model bridges the gap between the earlier, simpler Submariners and the more modern iterations. It's a watch that embodies both the robust functionality expected of a professional diver's tool and the undeniable elegance synonymous with Rolex. This article will explore the intricacies of the Rolex Submariner ref. 1680, delving into its technical specifications, the variations in its dials and bezels, and its current market value.
The Heart of the Beast: Caliber 1575
The Rolex Submariner ref. 1680 was powered by the Caliber 1575, a robust and reliable automatic movement. Based on the Caliber 1570, the 1575 boasts a frequency of 19,800 beats per hour (BPH), a standard for Rolex movements of that era. While not as high as the frequency found in later movements, the 1575 proved itself incredibly durable and accurate, capable of withstanding the pressures of underwater exploration and daily wear. One key feature that distinguished the 1575 was the inclusion of a quickset date function. This allowed for rapid adjustment of the date without having to cycle through the entire day, a significant improvement over its predecessor. The movement's construction, featuring a shock-resistant design and a high-quality balance spring, contributed to its longevity and reliability, solidifying its reputation for accuracy and resilience. Servicing a Caliber 1575, while requiring specialized knowledge, is generally straightforward, ensuring that these vintage watches can continue to provide decades of service with proper care.
Rolex 1680 Dial Variations: A Collector's Paradise
The dial is arguably the most visually striking element of the Rolex Submariner 1680, and its variations are a significant factor in the watch's desirability among collectors. The range of dial variations contributes significantly to the model's enduring appeal and its substantial price fluctuations in the secondary market. The most sought-after dials are often those exhibiting unique characteristics or subtle differences from the standard production. These variations are categorized based on several key features:
* Markings: The placement and style of the text, including "Submariner," "Rolex," "Oyster Perpetual," and "Superlative Chronometer Officially Certified," can vary slightly from one watch to another. Minor variations in font style, size, and spacing can significantly influence a watch's value.
* Markers: The hour markers are typically applied luminescent indices, but variations exist in their shape, size, and the type of luminous material used. Some examples include the “fat font” markers considered more desirable.
* Hands: The hands, responsible for indicating the time, can also exhibit differences in their shape and lume application. The presence of tritium lume (often exhibiting a creamy patina over time) versus later luminous materials impacts the aesthetic and value.
* Color: While black is the most common dial color, variations do exist, including rare examples with variations in the shade of black. These subtle differences are keenly observed by discerning collectors.
