The Rolex 1570 movement, a highly regarded automatic caliber produced by Rolex from the late 1970s to the mid-1980s, represents a significant chapter in the brand's horological history. While overshadowed by its successor, the ubiquitous and enduring caliber 3135, the 1570 holds a special place in the hearts of many collectors and enthusiasts. Understanding its intricacies, its place within the broader Rolex movement lineage, and its comparison to other calibers, particularly the 3135, offers valuable insight into the evolution of Rolex's watchmaking prowess. This article delves deep into the Rolex 1570, exploring its features, its strengths and weaknesses, and its current market position.
Rolex Caliber 1570: A Technical Overview
The Rolex caliber 1570 is a self-winding mechanical movement, renowned for its robustness and reliability. It’s a relatively high-beat movement, operating at a frequency of 28,800 vibrations per hour (8 beats per second), contributing to a smoother sweep of the seconds hand compared to lower-frequency movements. This higher frequency, however, demands more energy, potentially affecting power reserve. The 1570 boasts a classic architecture typical of Rolex movements of its era, featuring a robust construction designed to withstand the rigors of daily wear. Key features include:
* Automatic Winding: The movement utilizes a highly efficient self-winding system, ensuring consistent power reserve through the natural motion of the wearer's wrist.
* Hacking Seconds: A useful feature for precise time setting, the seconds hand stops when the crown is pulled out, allowing for accurate synchronization with a time source.
* Date Function: The 1570 incorporates a date display, neatly integrated into the dial at the 3 o'clock position. The date changes instantaneously at midnight.
* Shock Absorption: Like most Rolex movements, the 1570 incorporates shock-absorbing mechanisms to protect the delicate internal components from impacts and jolts.
* Jeweling: The movement features a significant number of jewels, typically 26 or 27, contributing to reduced friction and increased longevity.
Rolex 1570 Movement vs. Rolex Caliber 3135: A Comparative Analysis
Randallon's insightful post on TimeZone (TZ) highlighted key differences between the 1570 and the 3135, the movement that largely superseded it. While both are automatic, high-beat movements, several crucial distinctions set them apart:
* Bridge Design: The 1570 utilizes a more traditional bridge design, while the 3135 features a more modern and arguably more efficient layout. This difference, though subtle to the untrained eye, affects the movement's overall architecture and serviceability.
