Case 180 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve · uncertainty exercise

New here and reading spec sheets for the first time. Four terms keep tripping me up: complication, caliber, jewel count and power reserve. Short definitions would help, and so would a note on which ones actually matter when comparing two everyday watches.

Review focus: uncertainty. Leave the unresolved part visible instead of supplying a result. Use the original answer fragment “A complication is any function beyond…” as the discussion anchor; no new event or result is supplied.

Exercise RWI-09543/180: address this question within its stated limits.
