Specimen Profile
Use the attribute block as a hypothesis, not a conclusion. Each specification should be checked against what can actually be seen or mechanically verified. For this Datejust-style configuration, combine the Gold, 26mm case and bracelet specification before comparing date-window geometry; neighboring references can share many individual features. The attributes specify Folding Clasp; include its hinge, engraving and closure geometry in the photographic record. The listed crystal is Resistant Sapphire Crystal, so its seating and edge profile can be compared as a separate construction detail. The stated movement is Automatic with Cailber Rolex 2235,48Hours power reserve; keep that statement separate from what is physically verified.
Dial and Display Analysis
Prioritize geometry: marker centers, hand reach, text placement and aperture position can be compared objectively. Color should receive less weight because cameras and screens shift hue.
Machining and Assembly
External inspection should include the underside and clasp, not only the dial side. Machining, hinge geometry and link construction can add evidence that is absent from promotional photographs.
Internal Cross-Reference
Do not let a familiar caliber number end the investigation. Rotor design, bridges, balance location and setting sequence provide a more testable mechanical fingerprint.
Final Weighting
Weight structural and mechanical evidence above seller labels. The conclusion should remain persuasive even if factory names and marketing language are removed. The attribute block names Clean Factory / VSF(VS Factory); retain it as specimen-classification metadata, not as authentication proof.
















William Brown –
I was mostly interested in how the finished piece would look outside the product photos. I like the way date display and automatic movement fits into the rest of the design. I’m satisfied with it at this point.
