Rolex 3186 Movement: A Legacy of Precision
The Caliber 3186 is a testament to Rolex's meticulous engineering. It's a highly sophisticated movement boasting a wealth of features designed to ensure exceptional performance under even the most demanding conditions. Key characteristics include:
* Self-winding Mechanism: The movement utilizes a highly efficient self-winding system, ensuring consistent power reserve even with moderate wrist movement. This eliminates the need for manual winding, offering unparalleled convenience to the wearer.
