Technical Specifications
Measuring exactly 40mm in diameter and 12.0mm thick, the case integrates tungsten to reach 185.5g. Features high-polish flanks with brushed lug hoods.
Exhibits correct radial brushing with applied, faceted Roman numeral indices. Hands are treated with Chromalight-equivalent luminous material.

Why QF Factory for This Reference?
Many collectors ask: ��Why not GMF?��
While GMF produces excellent tungsten Day-Dates, QF��s specific weight distribution across both the case mid-section and the solid President links yields a highly balanced 185.5g profile. This prevents the top-heaviness sometimes experienced in earlier tungsten iterations, ensuring the watch sits flush on the wrist.
Full Disclosure: The white gold plating tone on the fluted bezel can appear marginally warmer than genuine rhodium-flashed 18K white gold under harsh fluorescent lighting.

Collector Q&A
Q: How does the weight of this QF Day-Date compare to the genuine Ref. 228239?
A: The genuine 18K white gold Day-Date 40 weighs roughly 200 to 210 grams depending on how many links are removed for sizing. This QF tungsten-infused edition weighs 185.5 grams, bridging the gap significantly compared to standard 135-gram steel replicas and providing a highly convincing heft on the wrist.
Q: Is the day and date change instantaneous at midnight like the genuine caliber 3255?
A: Yes, the Super Clone 3255 movement in this QF model features an instantaneous date and day jump mechanism, snapping crisply at midnight rather than slowly rolling over during a multi-hour window.
Q: Will the white gold plating on the fluted bezel fade over time?
A: The QF factory utilizes a durable PVD plating process for the bezel to simulate white gold. While highly resilient to standard daily wear, aggressive polishing or deep scratches can expose the steel base beneath. We recommend cleaning the bezel with a soft microfiber cloth only.
Q: What is the primary known flaw with this specific QF Heavyweight release?
A: While the 185.5g weight distribution is a major achievement, the day wheel font alignment can occasionally sit slightly left-justified or right-justified in the aperture depending on the specific day of the week. This is a common tolerance variance in current generation Clone 3255 movements.
