Daytona

I. Case Craftsmanship (904L Stainless Steel)

• Material:​ Same 904L stainless steel as the original — corrosion-resistant, scratch-resistant, with a heavy feel.

• Size:​ Diameter 40mm, thickness 11.9mm, identical to the original.

• Finishing:​ High-polished sides; brushed and polished transitions on lugs and case body; CNC precision-cut with sharp edges and no burrs.

• Lugs/End Links:​ Independently molded end links seamlessly connect to the case — flush at top, slightly concave at tail, recessed at bottom, matching the original structure.

• Caseback:​ Steel models have fine brushing; precious metal models (rose gold/white gold) feature engraved 750/Saint Bernard dog head marks — clear, deep, and accurate. New 4131 caseback has a wider flat surface for better wrist comfort.

• Crown/Guard:​ Symmetrical triple crown guards; crown logo matches the 3 o’clock marker in size and curvature; screw-down structure for authentic waterproofing.

II. Ceramic Bezel (Core Advantage of Original C Factory)

• Material:​ High-purity ceramic, nano-sintered — hard, scratch-resistant, fade-proof.

• Engraving:​ Laser-deep engraved, filled with platinum powder (not electroplated) — grainy texture, no blackening, no fading.

• Font:​ Three-dimensional rounded numerals/indices with micro-rounded edges, consistent with the original.

• Color Accuracy:​ JF Factory uses the original “ean bezel” — industry-leading color control; black/white/gray/rose gold bezels all match perfectly.

• Fit:​ Bezel sits flush with the case — no looseness, no gaps.

III. Dial

• Panda Dial:​ Exclusive dead-white dial — no yellowing, no red tint; most accurate contrast.

• Printing:​ Embossed 3D printing; fonts like “/Cosmograph” are clear, no ghosting, no misalignment.

• Sub-dials:​ Correct size and texture at 3/6/9 positions; sunburst radial pattern accurately replicated; clean borders with no burrs.

• Hour Markers:​ Three-dimensional inlaid markers with rounded edge polishing (sharp corners refined); flat top surface, rounded sides — consistent with the original.

• Precious Metal Models:​ Cement gray dial uses vacuum PVD plating (2–4μm), does not cover sunburst pattern; standard spray paint tends to be thick and prone to fading.

IV. Hands

• Material:​ Solid steel hands (not iron sheets), manufactured by Buff factory — substantial feel.

• Finishing:​ Fully mirror-polished, no burrs, no scratches; solid center post, no hollow feeling.

• Shape:​ Hour/minute/chronograph hands match the original in length, thickness, and curvature; second hand tip is sharp, not blunt.

• Lume:​ Even filling, neat edges, consistent with hour marker lume.

V. Markers & Lume

• Bezel Markings:​ Consistent depth on ceramic bezel markings; platinum filling is full with natural reflection.

• Dial Markings:​ Sub-dial printing is clear, no blurring, no misalignment.

• Lume Material:​ Swiss Super-LumiNova — bright, long-lasting, blue-green glow, close to the original.

• Application:​ Optimal height and neat edges on markers/hands; V2 upgraded to “original-style micro-grain texture,” not smooth surface.

VI. Bracelet (904L Stainless Steel)

• Material:​ Same 904L stainless steel as the case; layered brushing and polishing.

• Links:​ Brushed sides, polished center; smooth transitions; even gaps between links, flexible movement.

• End Links:​ Seamless connection to the case — no steps, no looseness; interchangeable with original structure.

• Feel:​ Weight and feel close to the original — not flimsy or cheap.

VII. Clasp

• Steel Models:​ Fold-over safety clasp, one-piece construction, no weld points; matte inside, polished outside; engravings (code + logo + dragon/phoenix mark) are clear and neat.

• New 4131 (Rubber Strap Model):​ Extended clasp with quick-adjust sliding mechanism (~3cm); memory steel plate is firm, not loose; adjustment feels solid.

• Fit:​ Clasp naturally connects to bracelet — comfortable to wear, not bulky.

VIII. Sapphire Crystal

• Material:​ High-transparency sapphire, double-sided anti-reflective coating; light transmittance ≈ 92%.

• Details:​ Laser-etched crown logo at 6 o’clock (152 dots); curved edge finishing; crystal slightly protrudes above the ceramic bezel, matching the original height; seamless connection to the case with no white edges.

IX. Non-regulated True Balance Wheel Integrated 4131, 4132 Movement!

The most important upgrade! Dandong non-regulated integrated 4131, 4132 movement.

• Balance Wheel:​ Copper alloy/beryllium copper balance wheel with 4 adjustable true weights on the rim.

• Hairspring:​ Nivarox-grade alloy hairspring, non-regulated installation, no outer stud interference.

• Adjustment Method:​ Rotating weights changes the balance wheel’s moment of inertia — precision tuning up to ±1 second/day.
