The Rolex 1665, the iconic Double Red Sea-Dweller, holds a special place in the hearts of vintage watch enthusiasts. Its robust construction, impressive water resistance, and compelling history make it a highly sought-after collectible. However, the world of vintage 1665s is fraught with complexities, particularly when it comes to dial authenticity. This article will delve into the fascinating, and often contentious, subject of the Rolex 1665 old service dial, exploring its characteristics, its implications for collectors, and its presence in the secondary market, referencing examples available from sources like Rolex 1665 dial for sale listings and detailed analyses from reputable vendors such as VintageWorn.com.
The Rolex 1665, produced from approximately 1967 to 1989, saw several variations in its dial throughout its production run. These variations, even subtle ones, can dramatically impact a watch's value and desirability. Among the most debated and often misunderstood dial types is the "old service dial." Unlike original, factory-fitted dials, old service dials are replacements installed by Rolex during service work. These dials were often fitted during servicing decades ago, and their presence can be a significant factor influencing a watch's authenticity and market value.
Identifying an old service dial requires a keen eye and a thorough understanding of Rolex's dial evolution. Several key characteristics distinguish an old service dial from its original counterpart:
* Printing Quality: Original Rolex dials, particularly those from the earlier production years, often exhibit a higher level of printing detail and precision. The fonts, the placement of text, and the overall sharpness of the printing are often noticeably different on service dials. Service dials can show variations in font thickness, slight misalignments, or a less crisp printing style compared to original dials. Detailed macro photography and comparison with known examples are essential for accurate assessment.
* Lume: The luminous material used on the dial and hands is another crucial indicator. Original 1665 dials utilized tritium, a radioactive substance that glows in the dark. Over time, tritium degrades, resulting in a characteristic creamy or beige patina. Service dials, depending on the era of service, might feature tritium, but the lume plot may differ in application, texture, or even color from original dials. Some service dials may even feature modern lume, easily detectable by its brighter, whiter, or different color luminescence.
* Markers: The shape, size, and application of the hour markers are meticulously scrutinized by collectors. Small discrepancies in marker shape, size, or the way they are applied to the dial can point to a service replacement. Original dials typically exhibit consistent marker characteristics specific to their production year. Service dials might show variations in these details, reflecting the complexities of Rolex's parts supply over the decades.
* "SWISS" and "T SWISS MADE T" markings: The positioning and style of the "SWISS" and "T SWISS MADE T" markings (depending on the production period) are crucial for authentication. These markings are subject to variations throughout the 1665's production run, and discrepancies from known examples for a specific production year can indicate a service dial.
