Clean Factory has released its latest iteration of the Daytona lineup with the 126503 two-tone model, featuring a black enamel dial and Moissanite diamond markers. As with all of their high-precision projects, this one begins not with renders—but with real Rolex models in hand.
A Two-Tone Daytona, Executed with Precision
This isn’t just any two-tone release. Clean Factory starts by re-engineering the watch from the genuine reference, crafting its components with exacting standards. The result is a Daytona that captures the warmth of yellow gold and the cool edge of black enamel in a single statement piece.
Black Dial: Zero Color Discrepancy
The dial uses an enamel-like finish that Clean Factory has meticulously color-matched. Unlike cheaper imitations that turn out glossy or grayish under lighting, this dial holds its depth and tone under natural and artificial light. The diamond indices are made from Moissanite—offering excellent fire and brilliance without resorting to inferior zirconia.
A Dial with Real Depth
The standout feature of the dial is its construction. A center sunburst section gives way to a matte-finished circular ring near the perimeter. Between them is a 30-degree polished bevel edge, adding visual depth and showcasing a level of craftsmanship that’s rarely replicated.
This level of detailing requires opening the genuine piece and studying its construction firsthand. It’s not something visible through photos alone.
Bezel and Case: Matte-Fill Perfection
The bezel font thickness, size, and black enamel filling are all modeled after the original. Clean Factory is currently the only replica producer achieving the correct matte-fill black lettering on the tachymeter scale. It’s a subtle feature, but collectors will notice it immediately.
The entire bezel was retooled for this release, not shared with previous batches. And the three-section end link (head link) was electroplated part by part to match the look and build of Rolex’s two-tone construction.
4131 Movement and Component Compatibility
Inside is the dedicated 4131 clone movement developed for the Daytona line. More than just functional, this movement mirrors the size and layout of the real thing—making case sets and components compatible with both Clean’s internals and the genuine 4131 structure.
High Development Costs and Low Compromises
Due to the complexity of the finishes, Clean Factory has experienced a significant drop in yield rate—resulting in higher production costs. The pricing reflects this. But for those who care about detail, it’s an understandable tradeoff.
Unlike other factories, Clean doesn’t rely on generic blueprints or photos. They purchase full sets of every new dial and color variation before designing a single part. That’s why their visual accuracy and part compatibility stay ahead of the curve.
Final Take
This 126503 Daytona from Clean Factory stands out not because it’s loud or flashy—but because it’s deeply considered. From the material choices to the way light reflects off the dial edges, everything about this release tells you it was built by people who truly care.
