The 2026 release from JF Factory has sparked fresh interest in the Rolex Daytona lineup, especially with its yellow gold-plated case and the integrated 4131 mechanical movement. This version, presented on a 904L stainless steel bracelet, aims to replicate the visual and tactile experience of the genuine model at a fraction of the cost.

Case Construction and Dimensions

The case is milled from 904L stainless steel, a material known for its corrosion resistance and density. At 40mm in diameter and 11.9mm thick, it matches the proportions of the original. The finishing process involves a polished case side with brushed lugs, and the caseback is a solid screw-down design that adds to the substantial feel. The crown guards are symmetrically shaped, and the winding crown is signed with the Rolex logo, maintaining the expected profile.

Ceramic Bezel with Platinum-Filled Engraving

One of the defining features is the ceramic bezel, which uses a high-purity nano-sintered material. The tachymeter scale is laser-engraved and then filled with platinum powder, creating a raised, textured finish that resists fading. Color matching is a strong suit here, with the black, white, gray, and rose gold variants closely aligning to the original. The bezel sits flush with the case, leaving no visible gaps.

Dial Details: Panda Style and Applied Markers

The panda dial is a highlight, with a pure white background that provides maximum contrast for the black subdials. Printing is done using a hydraulic three-dimensional process, ensuring crisp text for 'Rolex' and 'Cosmograph' without ghosting. The hour markers are applied, featuring polished edges and a slight curvature that follows the dial's slope. The subdials at 3, 6, and 9 o'clock have a radial sunburst finish that catches light similarly to the OEM.

Hands and Lume

The hands are cut from solid steel and polished to a mirror finish. They are shaped to match the original's dimensions, with a sharp tip on the central chronograph hand. Lume is applied evenly, using Super-LumiNova that glows blue-green in the dark, closely matching the authentic's luminous intensity.

Movement: Dandong 4131/4132

Inside beats a Dandong-based 4131/4132 movement, which is an integrated chronograph with column wheel and vertical clutch. The balance wheel is made of beryllium copper with four adjustable weights, allowing for fine regulation to within ±1 second per day. The hairspring is Nivarox-grade, ensuring stable timekeeping across different positions.

Bracelet and Clasp

The 904L steel bracelet features alternating brushed and polished links, with a smooth transition between the case and the first link. The folding clasp has a safety locking mechanism and is engraved with the Rolex logo. For the 4131 version, a new quick-adjust system allows for easy length changes of about 3cm, adding comfort and convenience.

Water Resistance and Crystal

The screw-down crown and caseback contribute to water resistance suitable for daily wear. The sapphire crystal is coated with an anti-reflective layer, offering 92% light transmission. A subtle laser-etched crown at 6 o'clock is visible only under the right lighting, a detail that adds authenticity.

Packaging and Authentication

This comes with an NFC-enabled warranty card that, when scanned, opens the official Rolex website—a clever touch that adds to the overall package. For those interested in acquiring this piece, inquiries can be directed to usaone.store, where the team can provide further details and pricing.
