Case 43 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve · source wording exercise

Reader check for “Beginner glossary Q&A: complication, caliber, jewel count, power reserve”: distinguish the discussion point “Two watches from different brands can share the same caliber…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: source wording. Retain the source wording beside any paraphrase.
