The Rolex reference number 78790, and its variant 78790A, represents a significant piece in the puzzle of Rolex watch history and aftermarket parts. These numbers don't identify a complete watch model, but rather a specific type of half-bracelet, a crucial component used in many iconic Rolex models. Understanding the nuances of the 78790 and its implications requires a deep dive into Rolex bracelet construction, reference numbers, and the thriving aftermarket for genuine pre-owned parts. This article explores the Rolex 78790 half-bracelet, its significance, its compatibility, and the importance of verifying authenticity when purchasing these sought-after components.
Deciphering the Rolex 78790 Bracelet: A Deeper Look
The Rolex 78790 and 78790A are not complete bracelets themselves. Instead, they represent a *half-bracelet*, meaning they constitute only one side of a full bracelet. A full Rolex bracelet typically consists of two half-bracelets, which are joined together at the clasp. This design allows for easier sizing and adjustment, a crucial feature given the variations in wrist sizes. The "A" suffix often indicates a minor, potentially subtle, variation in the design or manufacturing process compared to the original 78790. These variations could encompass things like minor changes to the clasp mechanism, the pin system, or even the subtle differences in the finish of the links. Pinpointing the exact differences between 78790 and 78790A without detailed technical specifications can be challenging, highlighting the importance of careful inspection and verification when purchasing these parts.
These half-bracelets are commonly associated with specific Rolex models, notably the GMT-Master II (16710) and the Explorer. The compatibility of the 78790/78790A is determined by the end links, the small, often curved, components at the ends of the bracelet that connect it to the watch case. The fit is precise, and incorrect end links will result in an improper and potentially damaging fit. This precise fit speaks to Rolex's commitment to quality and the importance of using genuine parts.
Rolex Bracelet Reference Numbers: A System of Identification
Rolex uses a complex system of reference numbers to identify its watches and components. These numbers aren't arbitrary; they contain crucial information about the watch's features, production year, and materials. For bracelets, the reference number, like the 78790, provides a quick way to identify the type of bracelet, its length (indicated by the number of links), and sometimes even subtle design variations. This system is vital for both collectors and watchmakers, enabling accurate identification of parts and ensuring compatibility during repairs or modifications.
The importance of understanding Rolex bracelet reference numbers, such as the 78790, cannot be overstated. It allows for accurate identification of parts during servicing, repairs, or restoration. It also allows collectors to verify the authenticity of their bracelets and avoid counterfeit parts, which are unfortunately prevalent in the market. The meticulous record-keeping by Rolex contributes significantly to the preservation and value of its timepieces.
