4130 Movement Service

A 4130 movement service refers to the maintenance or overhaul of the Caliber 4130, a mechanical chronograph movement. The Caliber 4130 is the in-house movement used in Cosmograph Daytona watches, introduced in 2000.

Here’s what a typical service of a 4130 movement entails:

1. Disassembly

• The watch is completely taken apart, including the movement, case, and bracelet.

• All components are inspected for wear or damage.

2. Cleaning

• The movement parts are ultrasonically cleaned to remove old lubricant, dirt, and debris.

3. Inspection and Replacement

• Each part is meticulously inspected.

• Worn or damaged components are replaced with genuine parts.

4. Reassembly and Lubrication

• The movement is reassembled and lubricated using specialized oils to reduce friction and ensure longevity.

5. Calibration and Adjustment

• The 4130 movement is calibrated to ensure it meets precise standards for accuracy (+2/-2 seconds per day).

• The chronograph functions (start, stop, and reset) are thoroughly tested for smooth operation.

6. Final Quality Control

• The watch undergoes rigorous quality control tests to ensure all functions work perfectly and it meets the expected standards.

How Often Should It Be Serviced?

Rolex generally recommends a full service every 7-10 years, though this can vary based on usage and environmental factors.

Cost of Service

The cost of servicing a 4130 movement can vary depending on factors such as the watch’s condition and the service center, but it typically ranges between $800 and $1,200 USD at an authorized RLX service center.
