Description
Clean Factory Rolex Daytona Ref. 116505-0015
Clean Factory delivers highly accurate dial typography and sub-dial proportions for the Everose 116505 reference.
Powered by Dandong Caliber 4130
The mechanical core of this piece is the celebrated Dandong 4130 automatic chronograph movement. Designed as a true 1:1 clone of the genuine Rolex caliber, it abandons the problematic modified 7750 architecture in favor of a genuine column-wheel and vertical clutch system. This ensures that engaging the chronograph pusher results in an immediate, smooth sweep of the central seconds hand. The movement also features a paramagnetic blue Parachrom hairspring emulation and KIF shock absorbers, contributing to its notable stability.
The Dandong 4130 clone is factory-regulated to perform within an impressive 卤3��5 seconds per day, rivaling the chronometric standards of many genuine Swiss calibers.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Fully functional 12-hour chronograph, 30-minute counter, and continuous running seconds
- �� Winding Direction: Bidirectional automatic winding
Technical Specifications
The case maintains the correct 40mm diameter and 12.2mm thickness, matching the genuine profile precisely thanks to the slim 4130 clone movement.
Features a deep black base punctuated by warm metallic accents on the sub-dials. The Chromalight luminescence is evenly applied with correct blue emission.
The tachymetric scale is deeply engraved into the rose gold plated bezel, filled with black lacquer that resists fading and matches the genuine typography.
Three-piece solid links with polished centers and brushed outers. The Oysterlock safety clasp features tight tolerances and a functional 5mm extension link.
Why Clean Factory for This Reference?
Many collectors ask: ��Why not BTF?��
While BTF (Better Factory) produces a highly capable 4130 Daytona, Clean Factory��s execution of the black 116505 dial remains structurally closer to genuine. Clean��s sub-dial rings feature a more accurate concentric texture and thickness, avoiding the overly thick sub-dial rings occasionally seen in rival batches. Furthermore, Clean��s crystal clarity and edge beveling provide a more authentic visual depth.
Full Disclosure: Because this piece is machined from 904L steel and plated, it weighs approximately 140 grams. The genuine 116505 is crafted from solid 18k Everose gold and weighs nearly 280 grams, resulting in a noticeable tactile difference in hand.

Collector Q&A
Q: Does the chronograph function exactly like the genuine caliber 4130?
A: Yes, the Dandong 4130 movement features a fully functional column wheel and vertical clutch, allowing the chronograph seconds hand to sweep smoothly without stuttering when engaged.
Q: How accurate is the rose gold plating tone compared to Rolex��s proprietary Everose?
A: Clean Factory has refined its plating to closely mimic the warm, slightly copper hue of Everose. However, under harsh fluorescent lighting, it may appear marginally warmer than the genuine solid gold alloy.
Q: Are the bracelet links plated on the sides as well?
A: Yes, the 904L Oyster bracelet features full-wrap rose gold plating, including the mid-link sides, ensuring no raw steel is visible when the wrist bends.
Q: Will the rose gold plating fade over time with daily wear?
A: While Clean Factory uses highly durable electroplating techniques, any plated watch is susceptible to wear on high-friction areas like the clasp and bracelet underside over several years of hard daily use.
