To commemorate the 20th anniversary of the Royal Oak Chronograph, the brand released the Ref. 26331OR.OO.1220OR.01. It is not merely a tribute to a classic; it is a mechanical evolution of modern luxury.

2. Visual Soul: Materials Consistent with the Original Blue Dial
The visual soul of the 26331OR lies in the high-contrast pairing of its deep blue dial with warm rose gold accents.
-
Pattern Artistry: The dial utilizes the same base material as the original, featuring the iconic “Grande Tapisserie” large checkerboard pattern. Through 2026-gen etching technology, the depth and light refraction of every groove are virtually indistinguishable from the genuine piece.
-
Expanded Contrast: The pink-gold-toned sub-dials—at 3 o’clock (30-minute), 6 o’clock (small seconds), and 9 o’clock (12-hour)—are perfectly proportioned. Luminescent rose gold hour markers and hands ensure exceptional legibility under any lighting.
3. The Wrist Feel: Perfect Dimensions, Thickness, and Weight
For the most discerning collectors, “hand feel” is the ultimate standard. The 2026 edition has conquered the two hardest challenges in replica engineering: Thickness and Mass.
-
Extreme 11mm Thickness: Previously, most modified chronographs were bulky. The 2026 edition utilizes a deeply modified movement to achieve the exact 11mm thickness of the original Cal. 2385, maintaining the elegant, slim profile of the Royal Oak.
-
Balanced Weighting: To match the 250g heft of solid 18K gold, high-density alloy inserts are integrated into the case and bracelet links. This ensures the watch has the same substantial “gravity” on the wrist, avoiding the “light steel” feeling typical of lower-tier versions.
-
Seamless Bracelet: The bracelet material and finish are consistent with the original’s tactile quality. Alternating brushed and polished surfaces provide a silk-like touch, while the double-folding clasp ensures a secure, ergonomic fit.
4. Mechanical Core: Full Functional Restoration
Despite the different architectural base, the operational logic remains faithful to the 20th Anniversary spirit.
-
Full Chronograph Functions: The modified 7750 architecture provides a smooth column-wheel-like pusher feel, accurately controlling the hours, minutes, small seconds, and the date display between 4 and 5 o’clock.
-
Reliable Output: With a power reserve of approximately 40 hours and a high-beat 28,800 vph frequency, it delivers the stability required for both daily wear and professional social settings.
5. FAQs (Frequently Asked Questions)
Q: Is the thickness and weight truly identical to the original? A: Yes. Through 2026-gen movement slimming and density-insert technology, the watch achieves the 11mm thickness and the approximately 250g weight characteristic of the 18K rose gold original.
Q: Will the rose gold plating on the bracelet fade? A: The watch uses a high-vacuum thick gold-plating process. As long as it avoids harsh chemicals and severe friction, the warm rose gold luster will remain vibrant for years.
Q: Is the movement reliable for daily use? A: The custom 7750 is one of the most reliable chronograph movements in the industry. It has been regulated for precision and is designed for low-maintenance, long-term stability.
