The most popular yellow gold ‘Yurenle Tape’ Daytona from CLEANS Factory (C Factory). Key features of this 116519 model:
1. Two identical cement-gray Daytona watches were purchased to open the mold—one was disassembled for precise measurement, while the other remains as a backup. The white gold panda dial’s numeric markings process is extremely complex, resulting in very high production costs.
3. Hour markers have been fully upgraded—flat surfaces are perfectly level, and side edges retain rounded corners, precisely matching the original.
4. Regarding the crystal: the original does not use ultra-clear glass, and since it’s flat, fingerprints adhere easily. Overly transparent crystals appear fake; future versions may upgrade to higher clarity glass as customers prefer it—perhaps this is the final stand for authenticity.
5. The case, being precious metal, features ‘750’ and Saint Bernard dog head engravings at the four bottom corners. This version meticulously replicates those details. Refer to detailed comparison images below. The only missing detail is a small tuft of fur on the dog’s head, which currently cannot be reproduced—an acknowledged shortcoming.
6. The side crown guards are individually crafted components. Compared to standard 116500 stainless steel cases, this area incurs the highest additional cost. Entirely reverse-engineered from genuine parts, made 1:1, and fully interchangeable.
7. The strap uses C Factory’s own rubber tape design—not just a gimmick. Detailed comparison photos are available below.
8. The clasp still employs AR’s buckle mechanism, with opening/closing feel and fine details identical to the original steel bracelet.
C Factory works surprisingly slowly, but we carefully perfect every component without simply copying official color images. This release is limited to the cement-gray variant only. Each future colorway will be accompanied by authentic vs. replica comparison images, reflecting our serious approach to the Daytona line. We ask for your patience—future releases will all be premium pieces. Prices may be slightly higher than competitors; opinions vary. Ultimately, we hope every watch enthusiast finds the timepiece they love most—even if it’s not made by C Factory.
