Description
QF Rolex Day-Date 40 Ref. 228238 Heavyweight Edition
The integration of a tungsten core to achieve 187.6g makes this QF Day-Date 40 a tactile benchmark in the replica market.
Powered by Clone 3255 Movement
The Clone 3255 automatic caliber provides the correct day and date instantaneous turnover at midnight, mimicking the mechanical behavior of the genuine Rolex caliber. It features a bidirectional winding rotor and operates at 28,800 vibrations per hour, ensuring a smooth sweep of the seconds hand. All pieces undergo evaluation against to verify proper escapement regulation before dispatch.
Standard ETA/clone base movements: 卤10��15 s/day.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Instantaneous day and date displays
- �� Winding Direction: Bidirectional
Technical Specifications
Monobloc middle case construction measuring 40mm in diameter and a highly accurate 11.8mm in thickness. The tungsten core brings the total mass to 187.6g.
Features a precise sunburst finish with crisp 18K gold plated Roman numeral appliques. The day and date window cuts are sharp with accurate font thickness.
Deep, sharp fluting that accurately mimics the light-play of the genuine precious metal bezels, maintaining correct geometric proportions.
Three-piece semi-circular links with solid end links, finished with polished center links and brushed outer links. Secures via a concealed folding Crownclasp.
Why QF for This Reference?
Many collectors ask: ��Why not GMF?��
While GMF also produces capable tungsten-weighted Day-Dates, QF��s specific execution of the 187.6g case provides a marginally better weight distribution across the monobloc middle case. Additionally, the green sunray dial tone on this QF batch exhibits highly accurate light reactivity compared to the genuine m228238.
Full Disclosure: The 18K yellow gold plating, while rich, can appear slightly warmer under harsh fluorescent lighting compared to the exact proprietary alloy used by Rolex.

Collector Q&A
Q: Does the day and date change instantly at midnight on this QF 3255 clone?
A: Yes, the Clone 3255 movement replicates the instantaneous jump mechanism for both the day and date complications, typically turning over within 5 minutes of midnight rather than slowly rolling over hours.
Q: How does the 187.6g weight compare to the genuine solid gold Day-Date 40?
A: A genuine 18K solid gold Day-Date 40 weighs approximately 200-210 grams depending on the number of links. At 187.6g, this tungsten-weighted QF replica is remarkably close, providing a highly authentic wrist feel compared to standard 130g steel versions.
Q: Will the 18K yellow gold plating fade or tarnish with daily wear?
A: While the QF factory uses a durable PVD-based gold plating over the 904L steel and tungsten base, it is susceptible to friction wear and chemical exposure over time. We recommend avoiding perfumes, saltwater, and abrasive surfaces to prolong the finish.
Q: Is the rotor noise noticeable on the QF Clone 3255?
A: The bidirectional winding rotor on this clone caliber is slightly more audible than the genuine Rolex 3255 movement. A light application of Moebius 9010 oil to the rotor bearings by a qualified watchsmith can significantly dampen this mechanical sound.
