I made a serious mistake while testing my watches' lume. I held my lamp too close (less than 20cm) which caused abnormal heatup to the watches. As I was going to sleep, I realized the situation and could barely touch the cases of the watches.
I was afraid and tested if they were broken. Result: everyone functioned properly though they were all completely under the heat. Instead of cooling them down with cold water, I let them cool off with time on the table.
Has anyone experiences on the issue? How well does a mechanical watch take heat?
