7. Authentication & Restoration Checklist

Originality checks

  • Serial and model engraved between lugs (invisible unless bracelet removed).
  • Rehaut engraving perfectly radial.
  • Dial lume uniform blue under UV.
  • Rotor stamped “Rolex 3235” with Geneva waves, not perlage.
  • Bracelet reference + clasp code correspond to case year.

Red flags

  • Service dials lacking coronet at 6 o’clock.
  • Aftermarket bezels with incorrect gold alloy.
  • Over-polished lugs losing chamfer lines.

Restoration guidance

  • Do not re-cut flutes; replace bezel if damaged.
  • Preserve factory brushing; light case refinishing only.
  • Replace gaskets + crown seals every 5 years.
  • Pressure-test after service (10 bar).
  • Document service with serial and date.

8. Summary

The Rolex Datejust 41 Ref. 126234 unites Rolex’s classic white-gold fluted bezel aesthetic with the advanced Cal. 3235 architecture. Mechanically robust, visually conservative, it represents the modern standard for the Datejust line. Its collectability stems from first-generation 3235 adoption and balanced proportions returning closer to vintage Datejust 36 ratios. Current market value (2025) remains strong, particularly for Wimbledon and blue-sunburst dials.
