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.
