The Rolex Explorer II, a robust and versatile tool watch, has a rich history marked by distinct iterations, each identifiable by its unique model number. Understanding these reference numbers is crucial for discerning collectors, potential buyers, and anyone seeking to navigate the complexities of the Rolex catalog. This article will delve into the various Rolex Explorer II model numbers, exploring their features, subtle design differences, and the information they reveal about the watch's history and provenance. We'll also touch upon related search terms like Rolex model number lookup, Rolex watch model numbers, Rolex watch model codes, Rolex Explorer price, Rolex serial number lookup, Rolex reference number lookup, Rolex serial number history, and Rolex watch serial numbers chart.
The Explorer II's defining characteristic, its fixed 24-hour bezel, is the key to understanding its functionality and the evolution of its design. This bezel, with its distinct gradations, allows the wearer to track a second time zone or differentiate between day and night hours with exceptional clarity. However, the implementation and appearance of this feature have varied across different model numbers, reflecting Rolex's continuous refinement of the design. This variation is precisely what makes deciphering the reference number so important.
Decoding the Rolex Reference Number System:
Before diving into specific Explorer II model numbers, it's crucial to understand the general Rolex reference number system. A Rolex reference number, typically consisting of four or five digits (sometimes more, especially with vintage models), acts as a unique identifier for a specific watch model and its variations. It doesn't directly reveal the serial number (which indicates the year of manufacture) but provides vital information about the case size, movement, dial configuration, and other key features. This number is often found engraved on the case between the lugs.
Key Considerations When Identifying a Rolex Explorer II:
* Case Size: The Explorer II has predominantly been available in a 40mm case size, though slight variations might exist due to manufacturing tolerances. Understanding the case size is essential for accurate identification.
* Movement: The movement type, such as the Caliber 3185 or later iterations, is another significant factor. The reference number will often reflect the movement used.
* Dial Configuration: The dial, with its hands, markers, and date window (if present), can vary significantly across different reference numbers. Details like the hand style, lume application, and date window placement are crucial identifying features.
* Bezel Material and Design: While the 24-hour bezel is a constant, the material (typically steel) and the precise design of the numerals and markings can differ subtly between reference numbers.
* Year of Manufacture: While the reference number doesn't directly indicate the year of production, it can help narrow down the possible manufacturing period, particularly when combined with the serial number.
Exploring Specific Rolex Explorer II Model Numbers:
Due to the numerous variations, listing every single Explorer II reference number would be impractical. However, we can examine some key examples to illustrate the range and significance of these numbers:
