A new updated version of the Daytona with the 4131 movement has been released, featuring minor exterior revisions. You may refer to our earlier articles if you need further clarification.

Two variants are available: two‑tone black dial with stick hour markers, and two‑tone black dial with moissanite stone markers.

This model was once again developed using the genuine watch as a mould‑reference. Every watch produced by Clean Factory is created after purchasing an original timepiece. No product is made merely from pictures, which reflects our responsible attitude towards watch enthusiasts.

The most prominent upgrade for the new 126503 lies in its 3‑6‑9 dial. It features a central sun‑burst finish, while the outer ring adopts a matte texture. Inside this outer circle sits a brightly polished bevel cut at a 30‑degree angle. This process is far more technically demanding than that of the previous 4130 movement version, resulting in a significantly lower yield rate. All of these fine‑grained details can only be discovered by taking the genuine watch apart.

Although the bezel appears similar to the 4130 version at first glance, side‑by‑side comparison reveals noticeable differences, therefore a completely new mould was produced. The hour markers are still set with moissanite stones.

Overall, the level of attention to detail from Clean Factory can be seen clearly from the comparison photos. Higher production costs lead to a slightly higher selling price than competing factories, and we appreciate your understanding.

Clean Factory purchases genuine watches for nearly every individual colour variant, which allows it to deliver the most comprehensive and authentic replica‑versus‑genuine comparisons on the market. Certain models undergo repeated revisions to perfect fine details, with some individual components requiring close to a full‑year‑long development cycle.
