Description
QF Factory Rolex Day-Date 40 Ref. 228239 �� Tungsten Weighted Edition
QF establishes the benchmark for tactile authenticity with its 184.3g tungsten-alloy construction, bridging the density gap of traditional steel replicas.
Powered by Super Clone 3255
The mechanical foundation of this reference is the Super Clone 3255 caliber. Unlike earlier ETA-based modifications, this movement is designed from the ground up to mirror the genuine Rolex architecture, operating at a high-beat 28,800 vibrations per hour. It features an instantaneous jump mechanism for the day and date discs, ensuring crisp transitions at midnight. All components are subjected to to ensure reliable long-term performance.
Standard clone base movement: typically 卤8��12 s/day when fully wound and resting dial-up.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Instantaneous day and date displays with double quickset
- �� Winding Direction: Bidirectional via perpetual rotor
Technical Specifications
Measuring 40mm in diameter and 12.2mm thick, the case utilizes a dense tungsten core to achieve a total weight of 184.3g, closely approximating 18k white gold.
Features accurate muted green tones with sharp dial printing, applied Roman numerals, and Chromalight luminescence on the hands.
The fluted bezel exhibits deep, sharp facets that capture light dynamically, though it presents a slightly cooler metallic hue than genuine white gold.
Semi-circular three-piece links with brushed outer and polished center segments, secured by a seamless concealed folding Crownclasp.
Why QF Factory for This Reference?
Many collectors ask: ��Why not GMF?��
While GMF also produces tungsten-weighted Day-Date models, QF��s specific distribution of the tungsten alloy within the mid-case and primary bracelet links yields a more balanced center of gravity on the wrist. Furthermore, QF��s rendering of the 60th Anniversary olive green dial avoids the overly vibrant saturation often seen in earlier batches from competing factories.
Full Disclosure: The fluted bezel, while structurally sharp, lacks the subtle warm luster inherent to genuine Rolex 18k white gold when viewed under direct sunlight.

Collector Q&A
Q: How does the weight of this QF Day-Date compare to the genuine 228239?
A: The genuine 18k white gold model weighs approximately 210g depending on the number of links. This QF tungsten-infused edition weighs 184.3g, significantly closing the density gap compared to standard 140g steel replicas.
Q: Does the day and date change instantaneously at midnight?
A: Yes, the Super Clone 3255 movement features an instantaneous jump mechanism for both the day and date windows, accurately replicating the genuine caliber��s double quickset functionality.
Q: Is the olive green dial color accurate to the 60th Anniversary edition?
A: QF has achieved a highly accurate muted olive tone with the correct sunburst effect. However, under harsh artificial light, the replica��s dial can appear slightly darker than the genuine Rolex lacquer.
Q: Are the President bracelet links entirely solid tungsten?
A: No. Only the core case and specific center links are tungsten-infused to achieve the 184.3g weight. The remaining components are standard 904L Oystersteel, which can cause slight balance differences on the wrist compared to a full solid gold piece.
