The Clean Factory Rolex Daytona Le Mans edition, fitted with a clone 4132 movement and transparent caseback, has become a talking point among replica watch enthusiasts. This article offers a straightforward comparison between Clean’s replica and the genuine Rolex 126519, based on real-world observations and natural-light comparisons, not promotional claims.

Dial & Sub-dial Texture: Real Light, Real Differences

One major visual element of the 126519 is the use of metallic silver rings within the sub-dials. Clean Factory recreates the bevel and brightness fairly well. Under outdoor lighting, the contrast and shine look close to the original. The dial color—an off-white matte instead of flat white—also lines up with the genuine watch.

However, under magnification, the concentric brushing inside the sub-dials is slightly rougher than on the authentic version. That said, it’s hardly noticeable without side-by-side scrutiny under good lighting.

Lume and Markers: A Balance of Consistency and Variation

• Lume Brightness: Clean’s lume performance holds up. Night visibility is solid, lasting several hours, and the application looks even.
• Indices and Hands: Applied markers are clean and well-positioned. Interestingly, Clean’s reference units showed that even Rolex’s own models vary—some had subtle differences in curvature and hand style, including leftover parts from the previous generation.

This unexpected discovery highlights an important point: even Rolex isn’t fully standardized across batches. Clean has mirrored that detail, for better or worse.

Case & Bracelet: Surface Finish, Weight, and Feel

The case uses 904L stainless steel, not white gold like the original. Naturally, this causes a slight color and weight difference. Still, in natural light and at a glance, both materials reflect similarly. The 40mm case and 12.2mm thickness feel authentic, and brushing transitions are done cleanly.

The caseback is where things diverge. Like the genuine Le Mans Daytona, Clean uses a transparent sapphire caseback. This detail is rare in the replica scene and adds another layer of realism.

Movement: What the Clone Cal.4132 Does Well

The Clean Factory version uses a visual and functional clone of the Rolex 4132. Chronograph operation feels smooth, and the running seconds hand is stable. The engraved rotor, gold text, and bridge design match the genuine layout fairly well.

Specs:

• Automatic movement
• ~70-hour power reserve
• Transparent caseback with visible rotor
• Chronograph functionality: hours, minutes, seconds

The movement isn’t COSC-certified, but for most users, it runs within acceptable accuracy and reliability ranges. The fact that Clean bought five genuine watches to use for calibration and teardown shows their seriousness.

Conclusion: Not Perfect, But Pretty Close

This version of the Daytona replica by Clean Factory shows notable effort. While the sub-dial texture and weight differ slightly from the real thing, the majority of details—including case profile, lume, dial layout, and chronograph function—are convincing.

It’s not about calling this a “perfect replica.” It’s about recognizing where it stands in the spectrum of modern replica craftsmanship.
