JF’s most discussed release, the 2026 Rolex card-free Daytona, is coming soon!
1. Case construction made from 904L stainless steel

· Material: Made from 904L stainless steel to meet OEM standards. It offers strong corrosion resistance, excellent scratch resistance, and a solid, premium feel.

· Dimensions: diameter 40mm, thickness 11.9mm, matching the OEM.

· Polishing: The case flanks are finished to a high polish, while the lugs and case body flow smoothly between brushed and polished surfaces. CNC machining ensures sharp lines, clean edges, and no burrs.

· Lug/head piece: The head piece is molded separately and connects to the case with a seamless fit. The top sits flush against the case, the tail has a slight inward curve, and the underside is also concave, matching the OEM structure.

· Bottom cover: The steel version features a fine brushed finish, while the precious-metal version in rose gold or white gold is engraved with 750/Saint Bernard dog head and has sharp, deeply engraved markings. The new 4131 case back is wider and wears more comfortably on the wrist.

· Crown/Shoulder Guards: The three shoulder guards are evenly balanced, and the crown LOGO matches the three-point size and curvature. The screw-in construction helps restore water resistance.

2. ceramic bezel (the core advantage of the original C factory)

· Material: Made from high-purity ceramic and nano-sintered for exceptional hardness, strong scratch resistance, and stable color retention.

· Engraving: Deep laser engraving with platinum powder filling, not electroplating, gives the bezel a rich textured finish that will not turn black or fade.

· Font: The numerals and markers are rendered in a three-dimensional, rounded style with softly finished edges, closely matching OEM.

· Color matching: JF factory uses the original “Clean ring”, the industry’s top standard for controlling color differences, and the black, white, gray, and rose gold rings are all closely matched.

· Fit: The ring opening sits snugly against the case, with no play or visible gaps.

3. dial (dial)

· Panda Daytona: The exclusive pure white dial has no yellow or reddish tint, creating the cleanest and strongest contrast.

· Printing: Hydraulic 3D printing keeps “Rolex/Cosmograph” and the other text sharp and easy to read, with no blur or alignment issues.

· Small dial: The 3/6/9 o’clock subdials are nicely proportioned and their textures work well together; the frosted radial and CD-pattern finishing has been faithfully reproduced, with crisp edges and no burrs.

· Pin (time scale): Three-dimensional applied markers with smoothly polished, rounded edges and a precise beveled finish; the top surface is flat, the sides are rounded, and the overall appearance matches OEM standards.

· Precious metal model: The cement gray dial is finished with vacuum PVD electroplating (2-4μm), which preserves the sunburst pattern instead of covering it up; by contrast, standard oil spraying can go on too thick or fade with time.

4. Pointer technology

·Material: solid steel hands, not iron sheet, OEM from Buff factory, with a solid, weighty feel.

· Polished crystal hands with a flawless finish, free of burrs or scratches; the solid central axle eliminates any hollow feel.

· Shape: The hour, minute, and chronograph hands closely match the OEM in length, thickness, and curvature, and the seconds hand has a pointed tip instead of a blunt one.

· Lume: The luminous material is applied evenly, with clean edges that match the lume on the applied markers.

5. Scale and lume

· Outer ring scale: The ceramic bezel markings are evenly engraved, filled with platinum, and catch the light in a natural way.

·Dial scale: The subdial markers are printed sharply and evenly, with no blurring or misalignment.

· Lume material: Swiss Super-LumiNova delivers strong brightness, a long-lasting glow, a blue-green hue, and an OEM-like appearance.

· Filling process: The lume height on the markers and hands is moderate, with crisp edges; the V2 version has been refined to deliver an OEM-style micro-grain finish instead of a perfectly smooth surface.

6. Bracelet en acier 904L inoxydable

·Material: Crafted from the same 904L stainless steel as the case, finished with layered brushing and polishing.

· Chain links: The outer sides of each link are brushed, while the center is polished, giving the bracelet a seamless look. Link spacing is consistent, so it wears and moves smoothly.

· Headpiece: integrated smoothly into the case with no gaps or looseness; the construction is interchangeable with OEM.

· Texture: The steel bracelet has a weight and feel that is very close to the OEM version, with none of the flimsy or low-quality sensation.

7. clasp

· Steel model: one-piece folding safety clasp with no solder joints; frosted finish on the inside and a polished exterior; the coding, LOGO, and dragon-and-phoenix markings are sharp and neatly applied.

· New 4131 (rubber strap model): comes with an extended clasp and quick-slide adjustment (about 3cm), plus a memory steel sheet that remains firm without loosening; the adjustment system feels solid and reliable.

· Fit: The clasp and bracelet join seamlessly and naturally, allowing a comfortable wrist fit that is less likely to irritate the hand.

8. sapphire crystal

· Material: High-transparency sapphire crystal with double-sided anti-reflective coating and approximately 92% light transmittance.

·Details: A 6-point laser crown with 152 points and rounded edges; the crystal has a slightly domed profile above the ceramic bezel, matches the OEM height, and does not leave a white edge where it meets the case.

9. No card and true Dharma code are integrated, 4132 movement!

The most significant update is now here: Dandong’s card-free integrated 4131 and 4132 movement.

Balance wheel: Copper-alloy or beryllium-copper balance wheel fitted with four adjustable real weights on the rim.

· Hairspring: Nivarox grade alloy hairspring, firmly installed and resistant to interference from external magnetic fields

· Adjustment method: Turn the regulator weight to change the balance wheel’s inertia, enabling precise regulation to within ±1 second per day

10. NFC warranty card

Includes one watch, one card, and an NFC electronic warranty card. To use it, turn on the NFC function on your mobile phone and place it near the warranty chip area on the back. Your phone will then automatically open the Rolex official website, where you can view the watch’s detailed information.
