Mechanical watches are precision instruments and naturally vary in accuracy depending on wearing habits, position, activity level, temperature, and other environmental factors.

A small daily variation is considered normal and does not necessarily indicate a defect.

If you notice a significant or sudden change in performance, we recommend monitoring the watch over several days before contacting our support team.

If the observed deviation appears excessive or continues over time, our technicians will be happy to evaluate the situation and determine whether service or regulation may be required.
