Description
Q-Factory Rolex Daytona 126519LN Tungsten Edition
A technical achievement in material science, bridging the tactile gap between steel clones and solid precious metal genuine pieces.
Powered by Calibre 4131 Clone
The Q-Factory utilizes the updated 4131 clone architecture, designed to reflect the aesthetic and mechanical upgrades of the newest Daytona generation. This movement features a fully functional vertical clutch and column wheel, ensuring the chronograph seconds hand starts without the tell-tale jump associated with horizontal clutch mechanisms. Each caliber is rigorously tested against to verify pusher crispness and amplitude stability under load.
�� Accuracy Profile:
Standard regulation for this complex chronograph clone yields an accuracy of 卤10��15 seconds per day. Positional variance is minimized, though running the chronograph continuously will impact overall isochronism.
- �� Power Reserve: Approximately 36 hours
- �� Complications: 12-hour chronograph, 30-minute counter, small seconds
- �� Winding Direction: Bidirectional automatic winding
Technical Specifications
THE BUILDTungsten-Steel Alloy (155g)
Engineered to mimic the specific gravity of 18K white gold. The case measures 40mm in diameter with a thickness of 11.9mm, matching the refined profile of the genuine 126500 series.
THE DIALBright Black & Steel
Features a deep sunburst black base with spray-coated silver sub-dials. The 18K white gold plated markers are filled with Chromalight for consistent, long-lasting blue luminescence.
THE BEZELBlack Cerachrom Ceramic
The monobloc ceramic bezel is highly resistant to scratches and UV fading. The recessed tachymetric scale is treated with a platinum dust coating to replicate the genuine metallic luster.
THE BRACELETOysterflex Elastomer
High-grade rubber strap containing flexible titanium-nickel alloy blades. Secured by a 904L Oystersteel Glidelock safety clasp, finished with double-layer PVD white gold plating.
Why Q-Factory for This Reference?
Many collectors ask: ��Why not Clean Factory?��
While Clean Factory produces exceptional Daytona dials and movements, their standard models utilize standard 904L steel, resulting in a watch that feels noticeably light on the Oysterflex strap. Q-Factory resolves this critical tactile discrepancy with its 155g tungsten-steel architecture, providing the heavy center of gravity required for the watch to sit correctly on the wrist without feeling top-heavy or hollow.
Full Disclosure: The double-layer PVD white gold plating, while highly accurate in tone, is an applied finish. Over years of heavy daily wear, deep scratches may expose the underlying tungsten-steel alloy, unlike solid 18K gold.

Collector Q&A
Q: Does the 155g tungsten case feel exactly like the genuine 18K white gold 126519LN?
A: The genuine 126519LN on Oysterflex weighs approximately 157g. At 155g, the Q-Factory tungsten-steel alloy provides an almost identical center of gravity, eliminating the hollow feel of standard 100g steel replicas and balancing perfectly against the tension of the rubber strap.
Q: Are all chronograph functions fully operational on the clone 4131 movement?
A: Yes, the 4131 clone mechanism features a fully operational column wheel and vertical clutch, allowing the sweep seconds, 30-minute counter, and 12-hour counter to function exactly as intended.
Q: How does the 18K white gold plating hold up to daily wear?
A: Q-Factory utilizes a double-layer PVD process infused with real 18K gold to achieve the correct warm grey-gold tone. While highly durable and resistant to oxidation, heavy abrasions or deep scratches can expose the steel-tungsten base layer over time.
Q: Is the dial color perfectly matched to the genuine Bright Black?
A: Q-Factory achieves a highly accurate sunburst effect on the black base, but under direct harsh sunlight, the spray-coated silver sub-dials can occasionally exhibit a slightly warmer metallic tone than the cooler rhodium finish found on the genuine dial.
