Case 17 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve

One more term that will come up is 'hacking', meaning the seconds hand stops when you pull the crown so you can set the time to the second. It's minor, but beginners often assume every automatic has it, and not all do. That rounds out the glossary: caliber means what, complication means extra functions, jewels mean bearings, power reserve means how long it runs, hacking means precise setting.
