The Rolex 18038, a reference often encountered with the serial number Z1397-F, embodies a fascinating intersection of horological history and the enduring debate surrounding chronometer certification. The phrase "old superlative chronometer officially certified" frequently associated with this model highlights a nuanced understanding of Rolex's quality control and the evolution of its chronometer designation. This article delves into the intricacies of the Rolex 18038 Z1397-F, exploring its place within the broader context of Rolex chronometer history and the implications of its "superlative chronometer" status.
Rolex Certified Chronometer: A Mark of Precision
Before analyzing the specific nuances of the 18038 Z1397-F, it's crucial to understand the significance of the "chronometer" designation itself. A chronometer isn't simply a high-quality watch; it's a timepiece that has undergone rigorous testing and certification by an independent body, typically the COSC (Contrôle Officiel Suisse des Chronomètres) in Switzerland. This testing involves subjecting the movement to various positions and temperatures to assess its accuracy and stability over time. Only those movements meeting stringent criteria receive the coveted chronometer certification, which is then proudly displayed on the watch's dial or caseback.
For Rolex, chronometer certification has been a cornerstone of its reputation for precision and reliability since the early 20th century. The brand's commitment to this certification has been unwavering, reflecting its dedication to creating timepieces of exceptional accuracy. However, the simple fact of certification doesn't fully capture the complete picture of Rolex's quality control.
Rolex Superlative Chronometer: Beyond COSC Certification
The term "superlative chronometer" represents a significant advancement in Rolex's quality control process. While the COSC certification guarantees a certain level of accuracy, Rolex goes a step further. After a watch receives its COSC certification, Rolex subjects it to its own in-house testing, significantly more rigorous than the COSC standards. This internal testing, conducted after the movement is cased, ensures the complete watch, not just the movement, meets Rolex's exacting standards for precision, power reserve, and water resistance. Only watches passing these stringent tests are designated as "superlative chronometers," a term that implies a level of quality exceeding even the already high standards of COSC certification.
This raises the question implicit in the title: does the "superlative chronometer" designation imply that some chronometers are inherently better than others? The answer is a nuanced yes. While all COSC-certified chronometers meet a minimum standard of accuracy, the variations within that standard can be significant. Rolex's superlative chronometer designation signifies that the watch has exceeded even the high bar set by COSC, indicating a superior level of performance and reliability. This superior performance is not merely a matter of marketing; it reflects real-world differences in accuracy and longevity.
