I recently acquired a Datejust with a cal. 1570 movement, circa 1977. Am I correct to assume there is no quick-set feature? And the big question: will I damage the movement by repeatedly adjusting the date? These are common questions among owners of vintage Rolex watches equipped with the caliber 1570, a movement that holds a special place in Rolex history, representing a significant step in the evolution of their automatic movements. This article will delve into the specifics of the Rolex caliber 1570, comparing it to its successors, examining its unique characteristics, and addressing the concerns regarding date adjustment.

Rolex Caliber 1570 Review:

The Rolex caliber 1570 is an automatic, self-winding movement introduced in the mid-1970s. It succeeded earlier movements like the caliber 1560 and predates the ubiquitous caliber 3135. This movement is characterized by its robust construction, reliability, and a distinctly vintage aesthetic. While not as technologically advanced as later movements, the 1570 is a testament to Rolex's commitment to quality and precision during this era. Key features of the caliber 1570 include:

* Automatic Winding: The movement utilizes a rotor system to automatically wind the mainspring, eliminating the need for manual winding. This self-winding mechanism is highly efficient, ensuring consistent power reserve.

* Date Function: The 1570 features a date display window at the 3 o'clock position, a staple of the Datejust line. However, and crucially for this discussion, it lacks a quick-set date function. This means that to adjust the date, the hour hand must be advanced until the desired date appears.

* Hacking Seconds: While not a standard feature across all 1570 movements, some examples do possess a "hacking" seconds function. This allows the seconds hand to stop when the crown is pulled out to set the time, enabling more precise time setting.

* Jewels: The caliber 1570 generally features 26 jewels, contributing to its smooth operation and longevity. These jewels act as low-friction bearings, reducing wear and tear on the movement.

* Shock Resistance: Rolex incorporated robust shock absorption mechanisms into the 1570, protecting it from the impacts of daily wear. This contributed significantly to its reliability and reputation for durability.

* Absence of Quick-Set Date: This is arguably the most defining characteristic of the 1570, and the source of many owner queries. The lack of a quick-set date necessitates rotating the hour hand through a full 24-hour cycle to advance the date by one day. This can be a time-consuming process, but it's a feature inherent to the movement's design.

The caliber 1570 was predominantly used in the Rolex Datejust line, but it may also be found in some Oyster Perpetual models from the same period. Its production period was relatively short, contributing to its collectible status among vintage watch enthusiasts. While not as widely discussed as later movements, the 1570 represents a significant chapter in Rolex's horological history, embodying the brand's commitment to quality and precision during a transitional period in their movement development.
