The Rolex Explorer, a watch synonymous with exploration and rugged dependability, has captivated watch enthusiasts for decades. This article delves into the specifics of the Rolex Explorer Automatic Chronometer, focusing on a pre-owned example – the 124270BKASO – priced at $7,495.00, while also exploring the broader context of Rolex chronometer certification and its place within the Rolex ecosystem. We’ll examine the differences between various chronometer classifications used by Rolex, touch upon related models like the Datejust, and consider the factors influencing the price of a pre-owned Rolex chronometer.
The Rolex Explorer 124270BKASO: A Pre-Owned Gem
The reference 124270BKASO represents a specific iteration of the Rolex Explorer. The "124270" denotes the model number, while "BKASO" likely refers to the specific internal Rolex reference indicating the black dial and potentially other subtle variations within that model year. The "pre-owned" designation highlights that this particular watch has had a previous owner, which often translates to a slightly lower price compared to a brand-new model, making it an attractive option for budget-conscious buyers seeking the iconic Explorer style and functionality. At $7,495.00, this price point suggests a well-maintained example in good condition, reflecting the enduring value of a Rolex timepiece. The price, of course, can fluctuate based on the watch's condition, box and papers included, and current market demand.
The allure of a pre-owned Rolex lies in the opportunity to acquire a piece of history, a watch that has already lived a life, potentially accumulating a unique patina and character. While a new watch offers the assurance of factory-fresh components, a pre-owned watch often represents significant value for money, especially for popular models like the Explorer. However, it's crucial to purchase a pre-owned Rolex from a reputable dealer to ensure authenticity and a satisfactory condition. Thorough inspection and possibly servicing by a certified Rolex technician are recommended before committing to a purchase.
Delving into Rolex Chronometer Certification:
The term "Chronometer" is central to understanding the Rolex Explorer and its prestige. It signifies that the movement within the watch has undergone rigorous testing and certification by an independent, officially recognized body, typically COSC (Contrôle Officiel Suisse des Chronomètres) – the Official Swiss Chronometer Testing Institute. This testing involves subjecting the movement to various positions and temperatures to assess its accuracy and precision. Only movements meeting the extremely strict standards set by COSC receive the coveted "Chronometer" designation.
Rolex Chronometer vs. Superlative Chronometer:
While COSC certification is a significant achievement, Rolex goes a step further with its own internal testing and certification – the "Superlative Chronometer" certification. This internal certification surpasses COSC standards, ensuring even higher levels of accuracy and performance. Rolex's Superlative Chronometer certification guarantees an accuracy of -2/+2 seconds per day after the watch has been cased and regulated. This is a significantly tighter tolerance than the COSC standard of -4/+6 seconds per day.
The difference between a COSC-certified chronometer and a Rolex Superlative Chronometer is subtle but significant for the discerning watch enthusiast. The Superlative Chronometer certification represents Rolex's commitment to unparalleled precision and quality control, exceeding even the already stringent standards set by independent testing organizations. Many modern Rolex watches, including the Explorer 124270BKASO, carry the Superlative Chronometer certification.
