3235 Movement Service

A 3235 movement service refers to the maintenance or overhaul of the ñ Caliber 3235, an advanced automatic movement introduced in 2015 as an evolution of the Caliber 3135. The 3235 is used in various modern models, including the Datejust 41, Submariner Date (post-2020), Sea-Dweller, and Yacht-Master 42. It features Rolex’s cutting-edge Chronergy escapement for improved efficiency, a 70-hour power reserve, and precision of +2/-2 seconds per day.

What Happens During a 3235 Movement Service?

1. Disassembly

• The watch is fully disassembled, including the case, bracelet, and movement.

• The Caliber 3235 is taken apart to inspect its components individually.

2. Cleaning

• All movement parts are cleaned in an ultrasonic bath to remove old lubricants, dirt, and debris.

3. Inspection and Replacement

• Components like the Chronergy escapement, Parachrom hairspring, and rotor system are inspected for wear or damage.

• Worn or damaged parts are replaced with genuine Rolex components.

4. Reassembly and Lubrication

• The movement is carefully reassembled and lubricated with precise oils to ensure smooth operation and longevity.

5. Calibration and Adjustment

• The movement is calibrated to Rolex’s strict Superlative Chronometer standards of accuracy (+2/-2 seconds per day).

• The balance wheel, escapement, and gear train are meticulously fine-tuned.

• The date-change mechanism and power reserve are tested to ensure reliability.

8. Final Quality Control

• The watch undergoes rigorous tests to ensure all features work flawlessly, including timekeeping, date function, and overall performance.

How Often Should It Be Serviced?

RLX recommends servicing the 3235 movement every 7-10 years, depending on usage and environmental factors. Regular servicing ensures that the watch continues to operate accurately and reliably.

Cost of Service

The cost of servicing a 3235 movement at an authorized service center typically ranges from $800 to $1,200 USD, depending on the watch’s condition and whether replacement parts are needed.

Unique Considerations for the 3235 Movement

• The Chronergy escapement is more efficient but requires precision handling during service.

• The Parachrom hairspring and 70-hour power reserve are hallmarks of this movement, which ensure longer-lasting performance compared to older calibers.
