Evidence Question — Fake-Watch Screening
When 179171JBK is screened through fake-watch screening, convert the suspicion into a testable question. Obtain a low-angle bezel view, isolate the disputed feature and compare it with the correct genuine generation instead of relying on one visual tell.
Research Focus: Caseback Transition
Use caseback transition to study the silhouette of 179171JBK. The 26mm specification provides context, but relative curvature, taper and transitions are more reliable than estimating dimensions from a photograph. Wear or refinishing must remain possible explanations.
Brush Direction
For 179171JBK, brush direction keeps confidence proportional to the available material. Better evidence is preferable to stronger wording, especially where seller photography is incomplete.
Evidence Question — Perspective Distortion
Image quality can materially change perspective distortion on 179171JBK. Use neutral light and a square-on macro; if the apparent difference shifts with camera angle, white balance or sharpening, reduce its diagnostic weight until a repeatable image is available.
Minute-Track Registration
For 179171JBK, minute-track registration offers repeatable visual evidence. Compare equivalent positions and look for a pattern rather than microscopic perfection; one irregular point should begin as a QC question, not an authenticity verdict.
















Jomes Miller –
The first thing that caught my attention was the overall configuration. The Black gives the model most of its personality, while the relatively restrained case keeps it from feeling too busy. The details are what make this version work for me.
