    A watch's heat resistance

    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?

    The mechanical components probably aren't affected much by the heat. It might thin out and displace the grease though, but I would imagine mechanical vibration (normal operation of the movement) would do that too. If there is anything that would be affected by the heat, it would be the rubber seals for waterproofing. But then I doubt heating it up with a light bulb would melt the rubber seals.

    I wouldn't worry about it. If you really want to charge up lume, get a UV flashlight - those really light it up, way better than an incandescent bulb.
    Lots of dive watches.

    It seems that high heat can ruin the lubricants (e.g. 18 different ones in a Zenith, they say) in a non-quartz watch so, if it were mine, I'd pay a bit closer attention to how well it works and perhaps move up my scheduled maintenance. Cosmetically, heat can also prematurely age dials and cause dial lacquers to lift or micro bubble, but you haven't mentioned that. You probably dodged a bullet by catching it in time. Good luck.

    Thanks for the answers. I'm going to check if my watches are losing or gaining the time. I think many watches are taking as much heat as mine under the sun behind a window.

    Let's hope they are ok.
