I have two, a Voigtlander Dynamatic II, the meter even still works well. I bought it in 1985 from a camera repair guy. Never did anything but take pictures with it since. The other is my OM-4 I bought new when it came out. Never had any service on it, just on one lens. Fell off a rock climb with it around my neck, it worked fine, I could walk one year later. It's been through blizzards at 4200 meters, and all over the mountains on week and longer trips. It just keeps working though it has some duct tape on it.
