Component Interface Study — Tachymeter Relationship
Begin the 178384NGBK_O review with tachymeter relationship, not with overall visual similarity. A bezel/dial registration view should expose the relevant geometry while limiting perspective and reflection errors that can make a correct feature look wrong.

Reference-Era Consistency Study
The 31mm format of 178384NGBK_O provides proportion context for reference-era consistency. Work from silhouette and relative geometry rather than attempting precise measurements from an unscaled photograph.

Condition-Versus-Origin
Use condition-versus-origin to test whether 178384NGBK_O tells one coherent reference story. Where the Black, Stainless Steel and stated movement intersect this feature, they should not contradict one another without an explanation such as service history.

Evidence Question: Reflection Control
The stated Automatic gives 178384NGBK_O a mechanical route into reflection control. Where the topic affects operation, record the actual sequence or architecture first and treat movement names or decorative markings as secondary evidence.

Testing Crown-Guard Geometry
The 31mm format of 178384NGBK_O provides proportion context for crown-guard geometry. Work from silhouette and relative geometry rather than attempting precise measurements from an unscaled photograph.
