Rolex Calibre 3130

Rolex Cal. 3130 is a genuine in-house manufacture movement. Rolex manufactures its own mainspring, escapement, and balance wheel. The Parachrom hairspring and Paraflex shock absorbers offer meaningful improvements in magnetic and shock resistance.

Rolex service intervals are long (typically 10 years), but manufacturer service is expensive (£500-£1500+). Third-party watchmakers can service Cal. 3130 but with more limited parts access than for older calibers.
