Description
Clean Factory Rolex Daytona 116505 Chocolate Dial
An uncompromising 1:1 replication of the 4130 architecture housed within precisely dimensioned 904L Oystersteel.
Powered by ShangHai Caliber 4130
The ShangHai 4130 clone movement represents a significant technical milestone in replica horology, matching the genuine caliber��s exact dimensions and component layout. Unlike modified 7750 bases, this dedicated chronograph engine utilizes a vertical clutch and column wheel, eliminating the telltale jump of the central seconds hand upon activation. We subject these mechanisms to , ensuring the KIF shock absorbers and blue Parachrom hairspring are properly seated for optimal amplitude.
卤5��8 s/day (ShangHai 4130 factory specification).
- �� Power Reserve: Approximately 36 hours
- �� Complications: Hours, minutes, sub-seconds display, and 12-hour chronograph
- �� Winding Direction: Bidirectional
Technical Specifications
The 40mm case achieves the genuine 12.2mm thickness, maintaining precise lug contours and a flawless polished finish across all surfaces.
The dial exhibits accurate sunburst graining, while the applied indices and hands are filled with correct blue-glowing Chromalight compound.
The fixed 18K rose gold plated bezel features meticulously filled engravings, offering the correct font weight and spacing for the tachymetric scale.
Constructed from plated 904L steel, the solid links articulate smoothly, and the clasp tolerances ensure a secure fit with minimal lateral play.
Why Clean Factory for This Reference?
Many collectors ask: ��Why not BT Factory?��
While BT Factory produces a highly regarded 116500 series, Clean Factory currently holds the advantage in precious metal plating tones, specifically their 18K rose gold formulation which avoids the overly brassy undertones seen in rival batches. Furthermore, Clean��s dial printing��particularly the sub-dial concentric circles��exhibits superior sharpness under magnification.
Full Disclosure: The overall weight (~142g) is significantly lighter than the solid 18K gold genuine (~200g+), an unavoidable limitation of plated 904L steel.

Collector Q&A
Q: How does the rose gold plating hold up to daily wear?
A: The 18K rose gold plating over 904L steel is applied via PVD, making it highly resistant to normal friction. However, it will scratch if exposed to abrasive surfaces, and deep gouges will reveal the steel beneath. We recommend avoiding chemical solvents and harsh polishing cloths.
Q: Does the chronograph function identically to the genuine Rolex 4130?
A: Yes. The ShangHai 4130 clone features a true column wheel and vertical clutch design. This allows the chronograph seconds hand to start without jumping and permits continuous running of the chronograph without severely degrading movement amplitude.
Q: Is the chocolate dial color completely accurate to the OEM model?
A: Clean Factory has achieved a highly accurate sunburst chocolate tone that shifts dynamically in natural light. While early replica batches struggled with overly red or flat brown hues, this current iteration closely mimics the genuine 116505��s depth and metallic sheen.
Q: What is the most notable tell on this specific replica?
A: The most significant tell is the physical weight. Because the case and bracelet are constructed from plated 904L stainless steel rather than solid 18K Everose gold, the watch weighs approximately 142 grams, which is noticeably lighter than the 200+ gram genuine piece.
