QF Factory Rolex Day-Date 40 m228239-0004 Tungsten Heavyweight Edition
The integration of a high-density tungsten core elevates this 185g Day-Date replica, providing the requisite heft previously absent in white gold super clones.
Powered by Clone Caliber 3255
The clone 3255 caliber accurately replicates the genuine Rolex movement architecture, incorporating the correct hand stack and a smooth-sweeping seconds hand. Most notably, it features the instantaneous day and date change mechanism, snapping sharply at midnight rather than rolling over gradually. Regulated via a free-sprung style balance wheel setup, this high-beat 28,800 vph escapement ensures stable chronometry. We mandate rigorous testing against our strict QC standards to verify the reliability of the day-date jumper springs and overall movement health.
⏱ Accuracy Profile:
±10–15 seconds per day. A deviation within this range is considered normal for this specific clone movement architecture when fully wound.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Center hour, minute, and seconds; instantaneous day and date in apertures.
- ✅ Winding Direction: Bidirectional
Technical Specifications

Why QF Factory for This Reference?
Many collectors ask: “Why not GMF?”
While GMF also produces tungsten-weighted Day-Date models, the QF Factory edition exhibits superior weight distribution across the case and bracelet, preventing the watch from feeling excessively top-heavy on the wrist. Furthermore, the integration of the clone 3255 movement with an instantaneous day/date change provides a more authentic mechanical experience compared to modified ETA-based alternatives.
Full Disclosure: The 904L steel, while polished exceptionally well, inherently lacks the subtle, warmer yellowish hue of genuine Rolex 18k white gold under specific lighting conditions.

Collector Q&A
Q: How does the weight of this QF tungsten edition compare to the genuine 18k white gold Day-Date 40?
A: This QF Factory model weighs approximately 185 grams due to its internal tungsten core. A genuine solid 18k white gold Day-Date 40 weighs around 200-210 grams depending on the number of links. While slightly lighter than genuine, it provides a significantly more accurate tactile experience than standard 130g steel replicas.
Q: Does the day and date change instantly at midnight like the genuine caliber 3255?
A: Yes, the clone caliber 3255 in this model features the correct instantaneous day and date mechanism. Both the day wheel and date wheel snap over sharply at midnight, rather than gradually rolling over several hours as seen in modified ETA movements.
Q: Are the bracelet links on the QF President bracelet solid tungsten?
A: No, the bracelet links are crafted from 904L Oystersteel with tungsten integrated into the core of specific links to increase mass. This ensures the exterior retains the correct finishing, color, and corrosion resistance of 904L steel while boosting the overall weight of the watch.
Q: Does the steel case visually match the 18k white gold of the genuine reference m228239?
A: While QF applies a high-polish finish to the 904L steel that closely mimics white metal, side-by-side with a genuine piece, the steel will appear slightly colder and more silvery. Genuine Rolex white gold has a very subtle, warm yellowish undertone that is difficult to replicate perfectly with raw steel.
