The Rolex Submariner 1680, affectionately known to many as the "Red Submariner" due to its iconic red "Submariner" text on the dial, holds a special place in the hearts of watch enthusiasts. Its production run, spanning from approximately 1966 to 1979, saw several subtle yet significant variations, making each example unique and highly sought after. This article will explore the intricacies of the 1680 case, focusing on restoration, common modifications, and the factors influencing the price of these legendary timepieces. We'll delve into the specifics of case refinishing, part replacement (including the crucial case middle), bezel inserts, and other components, providing a comprehensive understanding of what goes into maintaining and restoring a Rolex 1680.
The 1680 Case: A Closer Look
The case of the Rolex Submariner 1680 is a crucial element defining its aesthetic and functionality. Constructed from stainless steel, it's designed to withstand the rigors of underwater use, boasting impressive water resistance. However, decades of wear and tear can take their toll, necessitating restoration or repair. The case itself consists of several key components:
* Case Middle: This is the main body of the case, housing the movement and dial. It's the largest and most significant part, bearing the serial and model numbers. Replacement of the case middle, often necessary during restoration, requires careful sourcing of a genuine Rolex part to maintain authenticity and value. The part number "1680 ST" refers specifically to the case middle for this model.
* Case Back: This protects the movement and is usually engraved with the Rolex logo and reference number. Like the case middle, it can be refinished to remove scratches and imperfections. However, excessive refinishing can diminish the value of a vintage watch.
* Bezel: The rotating bezel, a defining feature of the Submariner, facilitates timing dives. The bezel insert, the colored ring within the bezel, is particularly prone to wear and fading. The 60-minute insert, often black on the 1680, is frequently replaced during restoration, with the reference number 5512 Black commonly used.
* Crown: The crown, responsible for winding and setting the time, is another potential point of wear. While not directly part of the case, its condition significantly impacts the overall appearance and functionality of the watch.
Restoration and Refinishing: A Balancing Act
Restoring a 1680 case requires a delicate balance between preserving originality and achieving optimal aesthetics. Refinishing, which involves smoothing out scratches and imperfections, is a common procedure. However, excessive refinishing can remove valuable patina and reduce the watch's overall value, especially for collectors who appreciate the history reflected in a watch's wear.
The process often includes:
* Case Back Refinishing: This involves carefully smoothing out scratches and blemishes on the case back, restoring its shine without removing too much material.
* Case Middle Replacement: As mentioned earlier, replacing the case middle is sometimes necessary due to significant damage or corrosion. This requires sourcing a genuine Rolex part, a process that demands expertise and access to reputable suppliers.
