RE: [Demo notebook] Workbench questions: what to record before asking for service · RWI-00499

Case 8 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve

A complication is any function beyond hours, minutes and seconds. A date window counts, technically, and so do a chronograph, GMT hand or moon phase. More complications usually mean more parts, more thickness and more service cost. For a first everyday watch, decide which functions you'd really use before treating them as value.
