JF’s hottest release, the 2026 Rolex card-free Daytona, is on the way!
1. Case construction: 904L stainless steel

·Material: Made from the same 904L stainless steel used by OEM, it offers corrosion resistance, scratch resistance, wear resistance, and a substantial feel on the wrist.

· Dimensions: diameter 40mm, thickness 11.9mm, identical to OEM.

· Polishing: The case sides are highly polished, while the lugs and case body use a smooth brushed-and-polished transition. CNC precision carving gives clean lines and sharp edges with no burrs.

· Lugs/headpiece: The headpiece is independently molded and integrated seamlessly with the case. The top sits flush with the case, the tail has a slight concave shape, and the underside is also concave, matching the OEM structure.

· Bottom cover: The steel version has a finely brushed finish, while the precious metal version in rose gold/white gold is engraved with 750/Saint Bernard dog heads. The engraving is crisp and deeply cut, and the new 4131 caseback is wider for a more comfortable fit on the wrist.

· Crown/Shoulder Guard: The three shoulder guards are symmetrical, and the crown LOGO matches the three-point size with an arc shape. The screw-in structure restores the original water resistance.

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

·Material: High-purity ceramic made with a nano-sintering process, delivering high hardness, strong scratch resistance, and stable color.

· Engraving: laser deep engraving with platinum powder filling, using a non-electroplating process for a pronounced textured finish that resists blackening and fading.

· Font: Numbers and scales are three-dimensional with rounded forms and gently softened edges, matching the OEM style.

· Color consistency: JF factory uses the original “Clean ring,” delivering industry-leading color control, with black, white, gray, and rose gold rings all accurately matched.

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

3. dial (dial)

· Panda Daytona: The dial is a pure dead white with no yellowing or reddish tone, creating the most precise contrast.

· Printing: Hydraulic three-dimensional printing keeps “Rolex/Cosmograph” and other text sharp and clean, with no ghosting or offset.

· Small dial: The 3/6/9 o’clock subdials match the correct size and texture, with restored frosted radial or CD patterns and a neat, burr-free border.

· Pin (time scale): The three-dimensional applied markers have rounded, polished edges; the blade angle is crisp, the surface is flat, the sides are rounded, and the look is consistent with OEM.

· Precious metal model: The cement gray dial uses vacuum PVD electroplating at 2–4μm, so the sunburst finish remains visible. By contrast, standard oil spraying can look heavy and is more likely to discolor over time.

4. Pointer technology

·Material: solid steel needle, not iron sheet. OEM by Buff factory, with a dense, sturdy feel.

· Polishing: Full needle crystal polishing with no burrs or scratches; the solid central axis gives it a substantial, non-hollow feel.

· Shape: The hour hand, minute hand, and chronograph hand all match in length, thickness, and curvature; the seconds hand is sharp and not dull.

· Lume: The lume filling is even, with clean, regular edges, matching the nail lume description.

5. Scale and lume

· Outer ring scale: The ceramic bezel scale features even depth, full platinum filling, and a natural reflective finish.

·Dial scale: The subdial markers are printed clearly, with no blur or misalignment.

· Lume material: Swiss Super-LumiNova offers high brightness, long-lasting glow, blue-green color, and an OEM-like appearance.

· Filling process: The lume height on the markers and hands is moderate, with clean edges; the V2 version has been refined to achieve an OEM-style micro-grainy finish rather than a smooth surface.

6. steel bracelet (904Lstainless steel)

·Material: Made from the same 904Lstainless steel as the case, with layered brushed and polished finishing.

· Chain link: The two outer sides of the chain link are brushed, while the center section is polished for a seamless look. The spacing between links is uniform, and the bracelet moves smoothly.

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

· Texture: The overall weight and feel of the steel bracelet is close to the OEM, with a solid, premium feel rather than something flimsy or cheap.

7. clasp

· Steel model: folding safety buckle, molded in one piece with no solder joints; the interior is frosted and the exterior is polished; the coding, LOGO, and dragon and phoenix marks are clear and tidy.

· New 4131 (rubber strap model): the clasp has been extended and now includes quick sliding adjustment (about 3cm). The memory steel sheet fits firmly without any looseness, and the adjustment action feels secure and solid.

· Fit: The clasp and bracelet connect naturally, so it wears comfortably and is less likely to irritate the hand.

8. Sapphire crystal

· Material: High-transparency sapphire crystal with double-sided anti-reflection coating and light transmittance of about 92%.

· Details: 6-point laser crown (152 points) with curved edges; the crystal has a slight dome over the ceramic bezel, matches the OEM height, and shows no white edge where it meets the case.

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

The biggest upgrade: Dandong card-free integrated 4131, 4132 movement

Balance wheel: A copper alloy and beryllium copper balance wheel featuring 4 adjustable real weights positioned around the edge.

· Hairspring: Nivarox grade alloy hairspring, installed without sticking or interference from outside springs

· Adjustment method: Turn the regulator weight to alter the balance wheel’s inertia, allowing fine adjustment to an accuracy of ±1 second/day

10. NFC warranty card

Includes one watch, one card, and an NFC chip electronic warranty card. To check the watch details, turn on NFC on your phone and hold it near the warranty chip area on the case back. It will automatically open the Rolex official website, where you can view the full information for the watch.
