Photo-Evidence Plan — Wrist-Scale Proportion
Use wrist-scale proportion to test whether 116139BL tells one coherent reference story. Where the Blue, Alligator and stated movement intersect this feature, they should not contradict one another without an explanation such as service history.
Condition-Versus-Origin
Place condition-versus-origin within an evidence hierarchy for 116139BL. Stable geometry and repeatable function normally deserve more weight than lighting-sensitive color, gloss or one piece of printing.
Testing First-Link Articulation
116139BL should not inherit a conclusion about first-link articulation from another watch in the OYSTER PERPETUAL family. Resolve generation and configuration first; visually related references can still differ in details that matter to authentication research.
Evidence Question: Metal-Tone Imaging Limits
Begin the 116139BL review with metal-tone imaging limits, not with overall visual similarity. A square-on macro should expose the relevant geometry while limiting perspective and reflection errors that can make a correct feature look wrong.
Evidence Question: Provenance Boundary
Begin the 116139BL review with provenance boundary, not with overall visual similarity. A end-link close-up should expose the relevant geometry while limiting perspective and reflection errors that can make a correct feature look wrong.


















Steven White –
This one just seemed like the better fit for what I wanted. The overall design is noticeable without being over the top. Nothing to complain about really The proportions also seem right to my eye I like the way the details come together It’s a fairly easy piece to wear The finished look is better than I expected.
