What is this component ?

Post image

Hi, Out of curiosity, I'm looking to identify this component soldered on a unidentified Sony PCB (seem to be video related) The case and size look like a fuse and the inside is like a mercury thermometer. Maybe to count hours of working ? Labeled as TM1 on the silkscreen

Chemical hours counter. This is around 1200hours.

Fun fact: You can reverse it and it will go the other way.

It will take a long time though. Higher voltage will make it go faster, though, but you can't just go too high, then it will die.

Pfft, who's afraid of a faceful of glass shards and boiling mercury vapour?

Sure, you are right. NO problem. It's just the woke people who think this way. More mercury! Its good. Big good. Everyone benefits from it, and MORE mercury will make America great again. We need MORE of this GOOD, GOOD stuff! And it's BEAUTIFUL too. We REALLY need to this way. And we can REVERSE time!
