What Should I Be Careful Of While Wearing My Mudita Radiant Automatic?

You should avoid subjecting your watch to strong shocks or impacts, which can occur during activities like contact sports, golf, or using heavy tools. 

Also, protect it from sudden and extreme temperature changes (like going from a hot sauna into cold water). Most importantly, be mindful to prevent dropping the watch, as a hard fall can easily damage the delicate internal mechanism.
