Evidence Question: Bezel Registration
For 279178-0007, bezel registration should be treated as construction evidence. Component interfaces, symmetry and proportion are more stable than gloss or color, while wear and refinishing remain alternative explanations.
Evidence Question: Replica Identification
For 279178-0007, replica identification is an authentication research question rather than a label-driven conclusion. Replica, clone and fake terminology can define the comparison context, but the useful evidence comes from same-reference geometry, function and component relationships.
Marker Spacing
279178-0007 should not inherit a conclusion about marker spacing from a visually similar reference. Generation and configuration must be established first because small reference changes can alter details that matter to identification.
Mechanical Verification — Date Centering
In this mechanical verification, keep date centering separate from provenance. Documents, seller claims and Clean Factory / VSF(VS Factory) belong to other evidence channels and should not rescue a weak physical observation.
Mechanical Verification — Chronograph Reset
279178-0007 should not inherit a conclusion about chronograph reset from a visually similar reference. Generation and configuration must be established first because small reference changes can alter details that matter to identification.




























Scatt King –
After comparing a few versions, this was the combination I preferred. The Resistant Sapphire Crystal is a useful specification to see, especially for something intended for regular wear. I’m satisfied with the specification and presentation.
