Description
VSF Rolex Daytona 116509-78599 �� The Weighted 4130 Benchmark
By integrating a 181.5g weighted case with the proven Dandong 4130 caliber, VSF delivers a compelling mechanical alternative to the genuine white gold reference.
Powered by Dandong Calibre 4130
The customized Dandong Calibre 4130 automatic winding movement mimics the exact 12mm thickness of the original architecture. It features a fully realized column-wheel and vertical clutch system, ensuring the central chronograph seconds hand engages without jumping. The three-layer baseplate incorporates genuine-spec chamfering and sun pattern finishing, while the custom KIF shock absorbers maintain balance wheel stability under daily wear.
The VSF Dandong 4130 is typically regulated to 卤3��5 seconds per day, demonstrating excellent amplitude and low beat error straight from the factory.
- �� Power Reserve: 60+ Hours (Dandong clone caliber)
- �� Complications: Central chronograph seconds, 30-minute counter at 3 o��clock, 12-hour counter at 9 o��clock, small seconds at 6 o��clock
- �� Winding Direction: Bidirectional
Technical Specifications
The 40mm case measures exactly 12mm thick, maintaining the genuine profile while utilizing weighted internal components to achieve an impressive 181.5g total mass.
Featuring sharp typography and accurate Chromalight lume application, the dial exhibits meticulous attention to detail, particularly in the dial color saturation and sub-dial ring depth.
The fixed tachymetric bezel utilizes a platinum plating structure for the engraved numerals, providing correct light refraction and depth against the polished steel background.
Constructed from solid 904L steel with polished center links, featuring an Oysterlock safety clasp with tight endplay tolerances and a functional 5mm extension link.
Why VSF for This Reference?
Many collectors ask: ��Why not Clean Factory?��
While Clean Factory produces a highly regarded Daytona with accurate dial components, VSF��s specific implementation of the 181.5g weighted case provides a tactile advantage for this white gold reference. Combined with the robust Dandong 4130 caliber, it bridges the physical weight gap that typically betrays steel replicas of precious metal watches, all while meeting .
Full Disclosure: The added mass relies on weighted internal components rather than solid gold, which slightly alters the center of gravity, making the watch head-heavy compared to the genuine article.

Collector Q&A
Q: Does the chronograph function exactly like the genuine Calibre 4130?
A: Yes. The Dandong 4130 features a fully realized column-wheel and vertical clutch architecture. The central seconds hand sweeps when engaged, and the 30-minute and 12-hour subdials track elapsed time accurately.
Q: How does the 181.5g weight compare to the genuine 116509?
A: The genuine solid 18k white gold 116509 weighs approximately 210g depending on the number of links. At 181.5g, this VSF weighted edition bridges the gap significantly compared to standard 140g steel replicas, offering a much more authentic tactile heft.
Q: Are the pushers and crown waterproof?
A: The watch is rated for 50 meters of water resistance, but the screw-down pushers and Triplock crown must be fully secured. Never unscrew the crown or operate the chronograph pushers while submerged.
Q: Is the rotor noise noticeable on this Dandong 4130 movement?
A: The Dandong 4130 is generally quiet, but the bidirectional winding rotor can exhibit a faint metallic whir under rapid wrist movement. This is a known characteristic of the clone caliber and does not impact timekeeping stability.
