Watch maintenance begins with observation and records

A watch gaining or losing time does not immediately point to a single fault. In mechanical watches in particular, usage, temperature, winding and position can affect timekeeping. The first step is therefore to describe the problem. Comparing your watch with the same reference over several days and noting the difference can be more informative than a single day's measurement. You can also record how long it was worn, when it was wound and whether anything unusual happened. These notes help establish a shared understanding when you consult a watchmaker. There is no single servicing interval that applies to every watch. The movement type, model instructions, intensity of use and previous service records should be considered together. The manufacturer's guidance for the particular model is a useful starting point. With an older watch, it can also be worth looking beyond whether it runs. A family note, an earlier service document or information about a replaced part may help explain its story. Keeping these records with the watch makes future examination easier. A culture of maintenance begins with careful observation. Describing the problem, recording the past and seeking appropriate expertise are ways to care for both the mechanism and the memories it carries.
