The Rolex Submariner reference 5512, a watch produced from 1959 to 1989, holds a special place in the hearts of collectors and enthusiasts alike. Its enduring appeal stems from a combination of robust functionality, elegant design, and a rich history intertwined with the evolution of diving technology. To truly appreciate the Submariner reference 5512, and to better understand what makes it special beyond the simple two lines of text describing it, it is crucial to delve into its intricate details, including its movement, a key component that significantly impacts its performance and value. Understanding the movement also allows us to place the 1974 5512 within its historical context.
A 1974 Rolex Submariner 5512 would almost certainly house the Rolex Caliber 1520. This movement, a workhorse of Rolex's mid-20th-century production, is a high-beat automatic movement known for its reliability and accuracy. While variations exist across the 5512's production run, the 1520 was prevalent during the mid-1970s. This movement boasts a frequency of 28,800 beats per hour (8 beats per second), contributing to its precise timekeeping capabilities. It's a self-winding mechanism, meaning it automatically winds itself through the movement of the wearer's wrist, eliminating the need for manual winding. The 1520 is also highly resistant to shocks and magnetic fields, vital characteristics for a professional diver's watch.
The importance of the chronometer certification cannot be overstated. A Rolex chronometer isn't just any accurate watch; it's a timepiece that has undergone rigorous testing by an independent, official body (COSC – Contrôle Officiel Suisse des Chronomètres) to ensure it meets strict precision standards. These tests assess the watch's performance across various positions and temperatures, ensuring consistent accuracy over extended periods. The presence of a chronometer certification on a Rolex, especially a vintage model like the 5512, significantly enhances its value and desirability among collectors. The certification is a testament to the watch's quality and the manufacturer's commitment to excellence.
This brings us to the visual aspects of the 1974 Rolex Submariner 5512, further enhancing its allure and collector appeal. Several features contribute to the distinct character of this model, and understanding these subtleties helps in identifying authentic examples and appreciating their nuances.
