Foreword
As one of the most coveted configurations in the Daytona lineup, the rose gold rubber strap(ref. m116505) represents Rolexās pinnacle of luxury chronograph design.We dissected a second-hand authentic piece and put the replica under a macro lens for comparison.Let you see every key difference.
Visual Discrepancies
- Material:Clean Factoryās version utilizes a 904L stainless steel base with PVD rose gold plating, while the genuine timepiece is crafted from solid 18K rose gold.
The genuine dial exhibits a silvery-white hue under strong light, transitioning to a subtle pink undertone in low-light conditions. Clean Factory has replicated this optical characteristic through specialized coating technology. Our photometric testing demonstrates their color shifts between bright/dim lighting are remarkably close to the authentic piece.
However, macro-photography reveals minor discrepancies in sunburst pattern groove width. That said, among current market offerings, Clean Factory achieves the highest fidelity to genuine specifications with 95%+ visual accuracy in real-world wearing conditions.

Cerachrom Bezel Comparison
The bezel engraving of the Clean factory is 0.02mm shallower than the genuine product (need to observe with a 20x magnifying glass).

Dial Detail Analysis
Dial Scale Nail Comparison
The authentic model features a yellow gold tone rather than rose gold, which Clean Factory has precisely replicated in a 1:1 ratio. As evidenced in the photographs, Clean Factory replica will be a little flatter.

12:00 Crown Comparison
The genuine piece exhibits superior three-dimensionality and fuller contours.

Dial Font Comparison
The font below 12 oāclock is a little thicker when viewed at macro distance. The font of the Clean factory is a little thinner, but it is difficult to detect from a normal perspective of the naked eye.

Hands Comparison
Both are solid shafts, and the shaft diameter tolerance under micro distance is ±0.02mm.

Chronograph Sub-dial Comparison
The subdials have been flawlessly replicated by Clean Factory, with printed numerals appearing to float above the track exactly like the genuine piece.

Case Hallmarks Comparison
From the pictures you can see there is still some difference.

Strap And Buckle Comparison
There is not much difference between the two. Both contain memory steel inserts, but the rubber of the Clean factory is a little harder.

Conclusion
In terms of overall appearance, itās virtually indistinguishable at normal social distances. Currently the most accurate rose gold color replication on the market. The 4131 movement maintains accuracy within ±5 seconds per day. However, due to material differences, thereās a weight variance of approximately 50 grams ā the genuine piece weighs 165g while Clean Factoryās version is 115g, making it slightly lighter to wear. Based on comprehensive comparison, the replication achieves remarkably high fidelity. Additionally, Clean Factory has introduced a full rose gold variant. Whatās your opinion on this model?
