Description
Clean Factory Rolex Daytona 116518LN 18K Gold Black Diamond Dial
A technically proficient clone that pairs the industry-leading Dandong 4130 movement with precisely executed Cerachrom and Oysterflex components.
Powered by Dandong Cal.4130
The Dandong Cal.4130 clone is widely recognized as one of the most sophisticated mechanical achievements in the replica industry. It features a paramagnetic blue Parachrom hairspring and KIF shock absorbers, ensuring stable amplitude across various positions. The integration of a vertical clutch guarantees a smooth sweep of the chronograph seconds hand without the stutter associated with horizontal clutch designs. All components are finished to a high standard, passing before final assembly.
The Dandong 4130 caliber in this specific Clean Factory production run is typically regulated to perform within 卤3��5 seconds per day, rivaling modern chronometer specifications.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Fully functional 12-hour and 30-minute chronograph registers, running seconds at 6 o��clock
- �� Winding Direction: Bidirectional via perpetual rotor
Technical Specifications
The 12.2mm thickness matches the genuine exactly. The polished finish provides the correct luster, though the 107.4g weight reveals its steel core.
Black dial with gold-toned sub-dials and synthetic diamond markers. The coronet at 12 o��clock and text spacing align closely with the genuine reference. Chromalight luminescence is applied to the hands.
Black Cerachrom ceramic insert. The engraved numerals are filled with a platinum-toned dust equivalent, providing the correct depth and legibility under direct light.
Oysterflex strap featuring flexible titanium and nickel alloy blades overmolded with high-performance elastomer. The 18K plated Oysterlock clasp operates smoothly with acceptable endplay.
Why Clean Factory for This Reference?
Many collectors ask: ��Why not BT Factory?��
While BT Factory offers excellent crystal clarity, Clean Factory consistently delivers superior dial accuracy, particularly regarding the sub-dial concentric circles and the tone of the yellow gold plating. Clean��s Cerachrom bezel also features sharper, deeper engravings that better mimic the genuine platinum fill.
Full Disclosure: The Oysterflex strap sizing is fixed per segment, meaning finding a precise fit requires careful selection of the correct strap length combination, and the 107.4g weight is significantly lighter than the solid gold genuine.

Collector Q&A
Q: Does the chronograph function exactly like the genuine 116518LN?
A: Yes. The Dandong 4130 movement features a fully functional vertical clutch chronograph. The sub-dials at 3 and 9 o��clock track minutes and hours respectively, while the 6 o��clock sub-dial displays running seconds.
Q: Is the weight of this Clean Factory Daytona accurate to the original?
A: No. Because this clone is constructed from 18K gold-plated 904L Oystersteel rather than solid 18K yellow gold, it weighs 107.4 grams. The genuine precious metal counterpart weighs significantly more.
Q: Will the 18K yellow gold plating fade or tarnish over time?
A: Clean Factory uses a durable PVD plating process that withstands daily wear well. However, like all plated watches, it can be scratched to reveal the steel underneath. Avoid abrasive chemicals and polishing cloths to extend its lifespan.
Q: How does the Oysterflex strap sizing work on this model?
A: Unlike traditional linked bracelets, Oysterflex straps come in specific length segments (e.g., E, F, G). While the Oysterlock clasp offers minor micro-adjustments, you must ensure you receive the correct strap segments for your specific wrist size, as the rubber itself cannot be cut or resized.
