Actually statistically speaking electronics will predictably have more chances of breaking/malfunctioning. However, what's even more important is that they are even less likely to be repairable. Of course we can wait another 52-54 years to see how electronic cams will fare . . .:whistling:
I do not know why I cannot able to get Olympus(OM-1ns) out of my head.
Nikon F, at-least on the picture(courtesy: Les Sarile) built like a pyramid.
If I have an OM-1 I would use it without the battery. I often use my OM-2 without meter although I do have to have the batteries in it.
1) Most mechanical cameras normally don't need new "parts" (apart from grease and foam every few decades), unless they get dropped or otherwise smashed.
2) When mechanical cameras do die, it's for a variety of reasons, so the "parts" cameras repairpersons keep handy can usually donate what's needed (unlike electronic cameras, where the "parts" camera probably died from the same electronic failure the camera to be repaired did).
3) Expertise... I rather quickly taught myself to do some fairly complicated repairs on mechanical cameras. I wouldn't even try to reverse-engineer a circuit board!
4) You evidently haven't used/handled many Nikon F or Spotmatic bodies (or a large number of other good mechanical cameras). Everytime I see one in a shop or flea market, I give it a quick check: the vast majority are in good working order (and my sample is probably well over on thousand). Most electronic cameras have a far lower percentage of "still-working" samples still around.
But if you choose to stick to your obviously deeply cherished beliefs despite empirical evidence and many people's real-life experience to the contrary, go ahead....
My answer was that all of the parts of the clock are still there and are very unlikely to have worn out or broken. The most likely cause of failure would be similar to cameras. i.e. lubrication getting too thick or gummed up with dust.
EDIT: I'm an electronic engineer but I would choose a mechanical solution to something every time.
I do not know, why they did not build a spot meter in OM-1n ;-)
* OM-3(Ti) is rather expensive. :-(
