Understanding Rolex Part Number 7912
The number 7912 identifies a specific Rolex reversing wheel. This component plays a crucial role in the watch's mechanism, specifically in the winding and time-setting process. In automatic movements, the reversing wheel ensures unidirectional winding of the mainspring, preventing damage from reverse rotation. Its precise function involves transferring power from the rotor (the oscillating weight) to the mainspring through a series of gears and levers. The quality and precision of this component are crucial for the smooth and reliable operation of the entire movement.
The listing specifies compatibility with calibers 1570, 1560, and 1530. These are all automatic movements used in various Rolex models throughout the years. Understanding the caliber number is essential for accurate part identification and replacement. Using the incorrect part can lead to malfunction or damage to the movement.
Rolex Caliber Numbers 1570, 1560, and 1530
These three calibers represent a family of automatic movements produced by Rolex. While sharing similarities in their architecture, they may have subtle differences in their specifications and features. Pinpointing the exact Rolex model that utilizes these calibers requires further investigation, possibly utilizing a Rolex model number lookup resource or consulting a specialized Rolex reference book.
* Caliber 1570: This caliber is known for its reliability and longevity, often found in classic Rolex models. More detailed information regarding its specific use in Rolex models would require further research into Rolex's historical production records.
* Caliber 1560: Similar to the 1570, the 1560 is an automatic movement recognized for its robust construction. Again, specific model identification necessitates accessing detailed Rolex archives or specialized databases.
* Caliber 1530: This caliber represents an earlier iteration of the automatic movement family. Understanding its exact application requires consultation of Rolex historical data.
The fact that the reversing wheel 7912 is compatible with these three calibers suggests it was likely produced during a period when Rolex employed these movements in their watches. The longevity of these calibers and the continued availability of replacement parts like the reversing wheel 7912 underscore Rolex's commitment to maintaining its vintage timepieces.
