Case 43 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log · source wording exercise

Summary draft for “Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log”: the answer addresses “Diameter alone tells you little…”; the related point is “Two cases 2mm apart in diameter can be within 1mm of…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
