⚠️ Did you know that changing the date on your mechanical watch at the wrong time could damage its movement?

In many mechanical watches, the calendar mechanism begins engaging around midnight. Using the quick-set date function during this period may put unnecessary stress on delicate components.

💡 A useful tip: Move the hands to 6 o'clock before adjusting the date, and always follow your watch manufacturer's instructions.

The exact restricted hours vary by movement, and some watches have mechanisms designed to avoid this issue.
