Cut from actual iron quartz, featuring a dark base with warm brown/copper veining. Set with sharply faceted baguette-cut diamond hour markers.
The fluted bezel exhibits deep, sharp facets that catch the light dynamically, coated in a thick layer of 18K Everose gold to match the case.

Why QF Factory for This Reference?
Many collectors ask: ��Why not GMF?��
While GMF also produces excellent tungsten-weighted Day-Dates, QF Factory��s integration of the genuine Eisenkiesel stone dial sets this specific release apart. GMF typically focuses on standard sunburst or motif dials, whereas QF has sourced actual iron quartz, ensuring the natural veining and visual depth matches the bespoke nature of the genuine Rolex stone dials.
Full Disclosure: The Everose gold plating over the tungsten core, while color-accurate, means that deep scratches will reveal the dark grey metal underneath, which cannot be easily polished out like solid gold.

Collector Q&A
Q: How does the weight of this QF tungsten version compare to the genuine Rolex 228235?
A: This QF edition weighs approximately 183.6g due to its heavy tungsten alloy core. A genuine solid 18K Everose gold Day-Date 40 weighs around 200-205g depending on the number of links attached. The QF comes within 10% of the genuine weight, which is a massive tactile improvement over standard 120g steel replicas.
Q: Are the veins on the Eisenkiesel dial printed or natural?
A: The dial on this QF model is cut from genuine Eisenkiesel (iron quartz) stone. As a result, the veining pattern is completely natural and unique to each individual watch; no two dials will look exactly alike, accurately reflecting how Rolex produces their stone dials.
Q: Does the day and date change instantly at midnight like the genuine caliber 3255?
A: Yes, the Clone 3255 movement in this model features an instantaneous jump mechanism for both the day and date discs, typically engaging within a few minutes of midnight rather than slowly rolling over.
Q: What is the primary concern with the tungsten alloy construction on this model?
A: While the tungsten core provides excellent heft, it is an extremely hard and brittle metal. If the watch sustains a deep scratch or heavy impact that penetrates the 18K Everose gold plating, it will reveal the dark grey tungsten underneath. Unlike solid gold, this cannot be easily polished out or laser-welded.
