Description
QF Factory Rolex Day-Date 36 Ref. 128238 Heavy Tungsten
A heavy-weight achievement that utilizes a tungsten core to resolve the traditional mass deficit of gold-plated replicas.
Powered by Clone Caliber 3255
The mechanical core of this replica is the Clone Caliber 3255, engineered to mirror the operational behavior of the flagship President movement. It features an instantaneous date and day-of-the-week flip at midnight, avoiding the slow transition seen in lower-tier calibers. Operating at a standard 28,800 vibrations per hour, the sweep seconds hand provides the smooth visual sweep expected of the genuine article, while ensure the hacking mechanism engages cleanly for precise time setting.
Regulated to 卤10��15 seconds per day. While it does not meet the Superlative Chronometer standard of 卤2 seconds, this variance is entirely acceptable for a mechanical clone in this tier.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Instantaneous day and date displays, stop-seconds
- �� Winding Direction: Bidirectional automatic winding
Technical Specifications
Constructed with a dense tungsten core, the case achieves a mass of 157g while maintaining the correct 36mm diameter and 11.8mm thickness. The 18K yellow gold plating is applied evenly across the polished flanks and brushed lugs.
The classic white dial features crisp black text printing and correctly proportioned markers. Chromalight-style lume is applied to the hands, offering adequate low-light legibility.
The fluted geometry is sharply cut to reflect light accurately. While the base metal is steel, the 18K yellow gold tone is chemically matched to approximate the warmth of Rolex proprietary alloy.
Equipped with semi-circular three-piece links, the bracelet incorporates tungsten to balance the heavy case head. The concealed Crownclasp operates with satisfying tension, exhibiting minimal lateral play.
Why QF Factory for This Reference?
Many collectors ask: "Why not GMF or BP Factory?"
While GMF produces highly regarded tungsten Day-Date models, QF Factory has optimized the weight distribution specifically for the 36mm case size, achieving a remarkable 157 grams without thickening the case profile beyond 11.8mm. This ensures the watch sits low on the wrist, avoiding the top-heavy feel that plagues earlier heavy-weight replicas.
Full Disclosure: The 18K yellow gold plating, while color-accurate out of the box, is susceptible to micro-scratching on the high-polish center links of the President bracelet over extended daily use.

Collector Q&A
Q: Does the day and date change instantaneously at midnight on the QF 3255?
A: Yes, the Clone 3255 movement in this QF edition replicates the instantaneous date and day-of-the-week flip at midnight, avoiding the slow, gradual transition found in lower-tier 2836-based replicas.
Q: How does the 157g weight compare to the genuine 18K gold Day-Date 36?
A: The genuine solid 18K gold Day-Date 36 weighs approximately 160-165 grams depending on the number of links. At 157 grams, the QF tungsten-infused version is within a 5% margin, making the weight difference nearly imperceptible on the wrist.
Q: Will the 18K yellow gold plating fade or tarnish over time?
A: The factory uses a durable PVD plating process over the 904L steel base. While highly resistant to tarnishing, high-friction areas like the clasp and the polished center links of the President bracelet may show underlying steel if subjected to deep scratches or heavy daily abrasion.
Q: Is the rotor noise noticeable on this tungsten-weighted model?
A: Like many Clone 3255 movements, the unidirectional winding rotor can produce a faint audible whirring sound in quiet environments. This is a known characteristic of the movement architecture and is considered normal mechanical operation.
