Description
QF Factory Rolex Cosmograph Daytona Ref. M116505-0017
QF delivers a mechanically robust 4130 clone paired with a highly accurate 18k rose gold plating tone that avoids the brassy hues of lesser tiers.
Powered by Shanghai Caliber 4130
The mechanical foundation of this Daytona is the widely respected Shanghai 4130 clone movement. Engineered to mirror the genuine Rolex architecture, it utilizes a true column wheel and vertical clutch system, ensuring that the chronograph seconds hand starts without the telltale jump seen on modified 7750 calibers. The movement is fitted with KIF shock absorbers and a replica paramagnetic blue Parachrom hairspring, offering excellent stability across varying positional variances.
The Shanghai 4130 in this QF batch is typically regulated to an impressive 卤5��8 seconds per day, providing highly dependable daily timekeeping.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Fully functional 12-hour chronograph, 30-minute counter, and running sub-seconds
- �� Winding Direction: Bidirectional via reversing wheel mechanism
Technical Specifications
The case measures a precise 40mm in diameter and an accurate 12.2mm in thickness, mirroring the 2022 genuine profile with correctly proportioned crown guards and pushers.
Exhibiting a rich sunburst finish, the dial features crisp typography and correctly chamfered sub-dial rings. Hour markers are filled with responsive blue Chromalight-style lume.
The fixed 18k rose gold plated bezel features deeply engraved tachymetric scale numerals, filled with correct black lacquer to ensure high contrast and legibility.
Constructed from solid 904L Oystersteel and fully plated, the three-piece link bracelet features a secure flip-lock clasp. Unlike the Glidelock clasp on dive models, this utilizes the correct Easylink 5mm extension system.
Why QF for This Reference?
Many collectors ask: ��Why not Clean Factory (CF) or BTF?��
While CF and BTF are renowned for their Dandong calibers, QF is frequently selected for this specific M116505 reference due to its superior Everose plating tone. QF��s proprietary alloy mix avoids the overly brassy or copper-heavy hues that occasionally plague other factories, providing a much closer visual match to genuine Rolex rose gold under natural lighting conditions.
Full Disclosure: As with all plated replicas, the 18k rose gold finish is a surface treatment. Deep scratches or prolonged exposure to harsh abrasives will inevitably reveal the 904L stainless steel base underneath.

Collector Q&A
Q: Does the chronograph function exactly like the genuine caliber 4130?
A: Yes, the Shanghai 4130 clone features a true column wheel and vertical clutch. The sweep seconds hand operates smoothly upon engagement, and the 3 o��clock and 9 o��clock sub-dials track minutes and hours accurately without the stutter seen on modified 7750 movements.
Q: How accurate is the 18k rose gold plating color on the QF edition?
A: QF has achieved a highly accurate Everose tone, avoiding the overly copper or brassy hues found on lower-tier replicas. It matches the warmth of the genuine Rolex alloy remarkably well under natural light.
Q: Will the 904L Oyster bracelet fit a larger wrist out of the box?
A: The standard Oyster bracelet accommodates up to an 8-inch wrist and features the correct Easylink 5mm extension system built into the clasp, allowing for minor on-the-fly sizing adjustments.
Q: What is the primary limitation of this QF rose gold model?
A: While the case dimensions and color are highly accurate, the watch is plated over 904L steel rather than cast in solid gold. Deep scratches or prolonged exposure to harsh chemicals can wear through the plating, revealing the silver-toned steel beneath.
