The world of vintage Rolex watches is a fascinating labyrinth of intricate movements, each with its own unique history and characteristics. While modern Rolex movements like the ubiquitous 3135 dominate current production, understanding the earlier calibers offers a glimpse into the evolution of this iconic brand. This article focuses on two such movements, the Rolex 1520 and the Rolex 1570, comparing their features, performance, and overall significance within the broader context of Rolex's horological legacy. We will also briefly touch upon related calibers and address some frequently asked questions.
The Rolex 1520 and 1570 are both automatic, mechanical movements representing different stages in Rolex's development. They predate the highly successful 3135 movement, which, as noted, forms the backbone of many contemporary Rolex calibers, including variations like the 3155 found in Day-Date models. The 3135's instantaneous date change at midnight is a significant improvement over earlier mechanisms and a feature absent in both the 1520 and 1570. However, these earlier movements hold their own appeal for collectors and enthusiasts, largely due to their historical significance and the craftsmanship involved in their construction.
Rolex 1520 Mechanical Movement: A Closer Look
The Rolex caliber 1520 is a robust and reliable automatic movement known for its durability. It's a relatively simple movement compared to later iterations, reflecting the technology available during its production period. While precise dates are difficult to pinpoint without specific model references, the 1520 generally finds its home in earlier Rolex Oyster Perpetual models, often from the 1960s and early 1970s. This movement is characterized by its relatively fewer parts compared to modern calibers, contributing to its straightforward construction and ease of maintenance (by experienced watchmakers, of course).
One key aspect of the 1520 is its lack of a quickset date. This means that to adjust the date, the user must advance the hour hand around the dial until the desired date is reached. This is a significant difference compared to the instantaneous date-setting mechanism of the 3135 and other later movements. This "slow" date-setting can be a point of contention for some, but it's a characteristic feature of the era and adds to the vintage appeal of watches equipped with the 1520.
The 1520's design emphasizes reliability and robustness, traits highly valued in Rolex's philosophy. Its construction utilizes high-quality materials and precise tolerances, ensuring longevity under various conditions. While not as technologically advanced as later movements, the 1520 represents a crucial step in Rolex's journey towards creating ever more precise and reliable timepieces.
Finding a Rolex 1520 movement for sale often involves scouring vintage watch markets and specialized dealers. The value of a watch equipped with a 1520 movement depends heavily on the overall condition of the watch, its case material, and any other distinctive features. Authenticity is paramount when purchasing vintage Rolex watches, and thorough inspection by a reputable watchmaker is highly recommended. Online forums and communities dedicated to vintage Rolex watches can be valuable resources for research and connecting with potential sellers. Furthermore, understanding the complexities of Rolex 1520 movement reviews requires careful consideration of the source and the specific context of the review.
