Case 28 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve

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.

Exercise RWI-20963/28: address this question within its stated limits.
