The Rolex Submariner 5512, a name whispered with reverence among watch enthusiasts, represents a significant chapter in the history of the iconic dive watch. Within the 5512 lineage, the transition from Caliber 1560 to Caliber 1570 marks a subtle yet important evolution, enhancing the watch's performance and solidifying its place as a highly sought-after collector's item. This article delves deep into the Rolex Submariner 5512 powered by the Caliber 1570 movement, exploring its history, key features, variations, and its enduring appeal in the modern market.
The Caliber 1570: A Refinement of Precision
Around 1965, Rolex upgraded the Submariner 5512, replacing the Caliber 1560 with the Caliber 1570. While outwardly similar, the internal improvements were significant. The Caliber 1570 operated at a higher frequency than its predecessor, resulting in increased accuracy and stability. This higher beat rate contributed to a more robust and reliable timekeeping experience, crucial for a professional diving instrument. The increased precision reflected Rolex's ongoing commitment to pushing the boundaries of horological excellence, ensuring the Submariner remained at the forefront of diving watch technology. The exact production dates for the 1570 within the 5512 are debated among collectors, with some suggesting a longer production run than others, but the general consensus places its introduction around mid-1965. It's important to note that precise dating of vintage Rolex watches often requires careful examination by experienced professionals.
Rolex 5512 Depth Chart: Understanding the Limits
The Rolex Submariner 5512, regardless of the movement inside, was famously rated for a depth of 200 meters (approximately 660 feet). While the depth rating remained consistent between the 1560 and 1570 variants, the improved accuracy of the 1570 arguably made the watch more reliable under pressure. It's crucial to understand that the "200 meters" rating refers to the watch's water resistance under controlled laboratory conditions. Actual performance in real-world diving conditions can be affected by numerous factors, including the age and condition of the seals, the intensity of the diving activity, and the water temperature. Therefore, modern diving practices recommend using purpose-built dive computers alongside any vintage dive watch, even one as robust as the 5512. There is no official "Rolex 5512 depth chart" as such; the stated depth rating is consistent across all models.
