The Rolex Calibre 1570 is a celebrated movement, a testament to Rolex's commitment to precision and reliability. While it's no longer in production, its legacy continues to resonate with collectors and enthusiasts alike. This article delves into the intricacies of the Calibre 1570, addressing specific concerns about its accuracy, servicing, and comparison to other Rolex movements, particularly the ubiquitous Calibre 3135. We’ll also address the question posed by our reader: "It's currently around +9 sec per day. Should I get it regulated? I would. Is this an easy (AD) adjustment, or would it have to go to Bexley?"
Rolex Calibre 1570 Review: A Legacy of Precision
The Calibre 1570, a self-winding mechanical movement, represents a significant chapter in Rolex's horological history. Introduced in the late 1970s, it quickly established itself as a reliable and accurate workhorse, powering various prestigious Rolex models. Its design incorporates several key features that contribute to its performance and longevity:
* High-Beat Frequency: While the exact frequency isn't explicitly stated as "freq" in the title and prompt, the Calibre 1570 operates at a frequency of 28,800 vibrations per hour (vph), or 8 beats per second. This higher frequency compared to some other movements contributes to increased accuracy and smoother seconds hand movement. However, it also means slightly increased wear on certain components over time.
* Robust Construction: The Calibre 1570 is known for its robust construction, featuring a substantial number of jewels (typically 27) that minimize friction and wear. Rolex's meticulous manufacturing processes and stringent quality control measures ensure durability and extended lifespan. This robustness is a key factor in its enduring reputation.
* Date Function: A practical feature for everyday wear, the Calibre 1570 incorporates a date complication, displayed through a quick-set date mechanism. This allows for easy adjustment of the date without affecting the timekeeping.
* Hacking Seconds: Another convenient feature is the hacking seconds function. When the crown is pulled out to set the time, the seconds hand stops, allowing for precise time setting. This is a significant improvement over movements without this feature, where setting the time requires careful estimation.
Rolex 1570 Movement Review: A Collector's Favorite
The Calibre 1570's popularity extends beyond its technical specifications. Its association with iconic Rolex models, its proven reliability, and its relatively smooth operation have made it a favorite among collectors. The movement's inherent accuracy and its ability to withstand the rigors of daily wear contribute to its enduring appeal. The fact that it's no longer in production only adds to its desirability, as it represents a piece of Rolex's horological heritage.
Many collectors appreciate the subtle differences in finishing and design compared to later movements. While the Calibre 3135, its successor, is arguably more refined in some aspects, the 1570 possesses a certain charm and character that resonates with enthusiasts. The sound of the movement, the feel of the winding mechanism, and even the subtle differences in the date wheel action contribute to a more visceral and engaging experience.
