Case 19 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log

Summary so far. Rows: diameter, lug-to-lug, thickness (method stated), lug width, crystal type, water resistance (as specified), movement family, production period. Each row has a source tag. Corrections go in the dated log with old and new values. If nobody objects, that's the template, and later posts should give evidence rather than restate opinions.
