Key Specifications (as generally understood):
* Type: Self-winding mechanical movement
* Jewels: Typically 31 jewels (this number can vary slightly depending on minor design iterations)
* Power Reserve: Approximately 48 hours
* Frequency: 28,800 vibrations per hour (4 Hz)
* Escapement: Swiss lever escapement
* Balance Spring: Parachrom hairspring (a Rolex-patented alloy resistant to magnetic fields and temperature variations)
* Balance Wheel: High-inertia balance wheel for enhanced shock resistance and precision
* Features: Date display, hacking seconds (seconds hand stops when the crown is pulled out), bidirectional self-winding rotor
* Construction: Finely finished with Côtes de Genève decoration and other traditional watchmaking embellishments.
The Calibre 1130’s significance lies primarily in its integration of Rolex's patented technologies, ensuring robustness, precision, and longevity. The Parachrom hairspring, for instance, significantly improves the movement's resistance to shocks and temperature fluctuations, ensuring consistent timekeeping performance even under adverse conditions. The high-inertia balance wheel further enhances shock resistance, contributing to the movement's overall resilience. The bidirectional self-winding rotor efficiently winds the mainspring, ensuring a longer power reserve. The hacking seconds function proves invaluable for precise time setting.
Repair and Maintenance Considerations:
Given the complexity and precision of the Calibre 1130, repair and maintenance should only be undertaken by authorized Rolex service centers or highly experienced watchmakers specializing in Rolex movements. Attempting repairs yourself could irreparably damage the delicate components.
Routine maintenance, typically involving cleaning, lubrication, and inspection of components, is crucial for maintaining the movement's accuracy and longevity. The frequency of servicing depends on factors such as usage and environmental conditions, but generally, a service every 5-10 years is recommended. Rolex's official service centers utilize specialized equipment and techniques to ensure that the movement is meticulously restored to its original specifications.
Common issues that may require servicing include:
* Reduced power reserve: This could indicate issues with the mainspring, winding mechanism, or lubrication.
* Inaccurate timekeeping: This could be due to various factors, including wear on components, lubrication issues, or damage to the hairspring.
* Malfunctioning date mechanism: Problems with the date wheel or its associated components can cause the date to skip or fail to advance correctly.
