The world of vintage Rolex watches is a treasure trove of horological history, filled with fascinating movements that represent the brand's relentless pursuit of precision and durability. Among these, the Rolex caliber 1560 and the Rolex caliber 1570 stand out as significant examples of the brand's evolution in automatic movements. While both are highly regarded for their performance, they differ in key aspects, sparking ongoing discussions among collectors and enthusiasts. This article delves deep into the comparison between the Rolex 1560 and 1570, exploring their technical specifications, reliability, and market presence, aiming to provide a comprehensive understanding of these two influential movements.
The Core Difference: Beats Per Hour (BPH)
The most immediate and significant difference between the Rolex 1560 and 1570 lies in their beat rate. The Rolex 1560 operates at a frequency of 18,000 beats per hour (bph), while the Rolex 1570 boasts a higher frequency of 19,800 bph. This difference in frequency directly impacts several aspects of the movements, including power reserve, accuracy, and the overall feel of the watch on the wrist.
A higher beat rate, like that of the 1570, generally leads to smoother seconds hand movement, providing a more refined and visually appealing sweep. However, it also typically means higher energy consumption, resulting in a potentially shorter power reserve compared to a lower-beat-rate movement like the 1560. While the exact power reserve for both movements varies depending on individual watch conditions and usage, the 1560 generally offers a slightly longer power reserve. This difference, while often not drastically significant in practical terms, is a factor to consider.
Reliability: A Matter of Debate
The question of which movement – the 1560 or the 1570 – is more reliable is a subject of much discussion amongst Rolex aficionados. There's no definitive answer, as both movements are known for their robustness and longevity when properly maintained. Anecdotal evidence and servicing records suggest that both movements have comparable reliability rates, with failures stemming more from general wear and tear or lack of maintenance rather than inherent design flaws.
The higher beat rate of the 1570 might, in theory, introduce slightly more stress on the components, potentially leading to slightly higher wear over time. However, Rolex's rigorous manufacturing standards and the quality of materials used mitigate this risk considerably. Similarly, the 1560, with its lower beat rate, experiences less stress, potentially contributing to its longevity.
Ultimately, the reliability of both movements is largely dependent on factors such as proper servicing, careful handling, and the overall condition of the watch. A well-maintained 1560 can easily last for decades, just as a well-maintained 1570 can.
