116520 balance

The balance wheel in the Caliber 4130 oscillates at a rate of 28,800 vibrations per hour, which is a significant factor in the chronograph's precision. This level of oscillation allows for a highly accurate measurement of time, making the Rolex 116520 perfect for professional timing needs, while also ensuring stability and longevity for everyday use.

The Parachrom hairspring in the Caliber 4130 is a key feature that allows the Rolex 116520 to resist shocks and magnetic fields. This innovative balance spring helps improve the watch's overall accuracy and reliability, ensuring that the watch maintains excellent timekeeping despite exposure to daily wear or environmental stresses.

The Chronergy escapement increases the efficiency of the Rolex 116520's movement by improving its energy transfer and reducing friction. This makes the balance wheel system more efficient, providing better performance and longer power reserve. It’s designed for maximum precision and energy efficiency, significantly contributing to the accuracy and durability of the chronograph.

The balance bridge in the Caliber 4130 holds the balance wheel firmly in place while maintaining shock resistance, which is essential for a professional chronograph. This feature allows the watch to withstand the impact of activities such as motorsport and extreme sports, ensuring that the balance remains intact for accurate timekeeping even under high-stress conditions.

The chronograph pushers on the Rolex 116520 are designed for smooth activation without affecting the balance wheel or disrupting the timing mechanism. Rolex’s precision engineering ensures that even with frequent use of the chronograph function, the balance wheel system maintains its integrity, providing consistent and accurate performance throughout the watch’s lifespan.
