Case 29 — Maintenance question: how do I tell if an automatic actually needs service?
Common advice says service every five years, but service is expensive and some people run watches much longer. What observable signs actually indicate a mechanical watch needs attention, as opposed to just being due on a calendar?
Exercise RWI-03829/29: address this question within its stated limits.
