Description
VSF Rolex Daytona ref. 116519 Black/Red Dial on OysterFlex
A technically proficient replication leveraging the industry-leading Dandong 4130 caliber within a precisely dimensioned 12.5mm case.
Powered by Dandong Caliber 4130
The Dandong 4130 is widely regarded as one of the most sophisticated clone movements in horology, designed with a genuine vertical clutch and column wheel architecture. By eliminating the necessity for a 7750 transfer module, this movement achieves the exact 12.5mm case thickness of the genuine article. It is equipped with a paramagnetic blue Parachrom hairspring and KIF shock absorbers, ensuring robust anti-magnetic properties and reliable amplitude across varying states of wind.
VSF Dandong calibers are typically regulated to 卤3��5 seconds per day prior to casing, exhibiting exceptional isochronism and minimal positional variance.
- �� Power Reserve: 60+ Hours (Dandong clone caliber)
- �� Complications: Hours, minutes, sub-seconds at 6 o��clock, and fully functional 12-hour chronograph
- �� Winding Direction: Bidirectional via perpetual rotor
Technical Specifications
Machined to an exact 40mm diameter and 12.5mm thickness, featuring alternating polished lug hoods and brushed case flanks.
Displays crisp typography and accurate sub-dial spacing, complemented by Chromalight indices that emit a sustained blue glow.
Constructed from 904L steel but finished to mimic the luster of 18k white gold, featuring deep, legible tachymetric scale engravings.
High-density elastomer over flexible metal blades, secured by a 904L steel deployant clasp with precise endplay tolerances.
Why VSF for This Reference?
Many collectors ask: ��Why not Clean Factory?��
While Clean Factory produces an exceptional 116519 case and dial, VSF��s access to the Dandong 4130 movement provides unparalleled winding smoothness and a superior power reserve. Furthermore, VSF��s proprietary sapphire crystal offers industry-leading transparency, minimizing reflections over the black dial more effectively than rival iterations.
Full Disclosure: Because this case is milled from 904L stainless steel, it cannot replicate the distinct heft or the subtly warm, yellowish hue of genuine 18k white gold, making it noticeably lighter on the wrist.

Collector Q&A
Q: How does the weight of this VSF 116519 compare to the genuine Rolex?
A: Because this replica is milled from 904L stainless steel rather than solid 18k white gold, it is significantly lighter than the genuine piece. The genuine weighs over 150 grams on OysterFlex, whereas this steel model weighs approximately 115 grams.
Q: Is the chronograph fully functional on the VSF Caliber 4130?
A: Yes. The Dandong 4130 is a true 1:1 clone movement featuring a functional column wheel and vertical clutch. All sub-dials (running seconds at 6 o��clock, 30-minute counter at 3 o��clock, and 12-hour counter at 9 o��clock) operate exactly as they do on the genuine caliber.
Q: Can the OysterFlex strap be adjusted for smaller wrists?
A: The VSF OysterFlex strap includes internal titanium-nickel alloy blades coated in elastomer, mimicking the genuine structure. Micro-adjustments can be made via the clasp��s internal mechanism, but major sizing requires swapping the rubber strap segments just like the authentic version.
Q: What is the main known flaw of the VSF Daytona compared to Clean Factory?
A: While VSF utilizes the superior Dandong 4130 movement with a 60+ hour power reserve, collectors often note that Clean Factory��s dial typography and sub-dial concentric circles are marginally closer to genuine. Additionally, the steel case cannot replicate the warm, yellowish hue of genuine Rolex 18k white gold.
