I am wondering... how many owners here of the older Mercedes still have a properly functioning instrument cluster clock?

I hope I do not jinx myself, but when I got my 85' 380SE, I was amazed that the instrument cluster clock was still in perfect working order. As far as I can tell, it has never been repaired/replaced. I find it amazing, because out of all of the older cars I have owned with an instrument cluster clock, none have ever operated. Seems to be an extremely common problem on ALL older cars. Aside from the A/C systems on cars, this seems to be the next thing that typically goes out.

Knowing my luck, I just jinxed myself and the clock will now be on the fritz.
