Evidence Question — Caseback Transition
For 178271GWT_O, caseback transition should be compared from a square-on macro. Structural form survives lighting changes better than surface shine, making it a stronger reference-specific clue.
What to Verify: Case-Bracelet Proportion
On 178271GWT_O, case-bracelet proportion deserves close side views rather than a wrist-only photograph. The strongest evidence comes from the case, end links and clasp telling the same construction story.
Polishing History
For 178271GWT_O, polishing history should be read across several components. A softened edge or newer-looking part may reflect service history rather than counterfeit manufacture, and the evidence should preserve that alternative explanation.
Research Focus: Movement Architecture
For 178271GWT_O, movement architecture should be demonstrated rather than inferred. Crown positions, hand behavior or internal architecture—where legitimately accessible—can expose relationships that polished photography cannot show.
Research Focus: Dial-Rehaut Interface
For 178271GWT_O, dial-rehaut interface tests component compatibility. A focused true side profile can help distinguish systematic geometry from one isolated QC imperfection.


























Mork Brawn –
I kept coming back to this model when I compared the available options. The case thickness of 10.9mm is worth noting alongside the 31mm; together they give a clearer idea of the proportions. I had a question about the configuration before ordering, so having the specifications available was useful. So far, the choice looks right to me.
