The mechanism looks relatively simple compared to the modern SLR, but the LTMs are wonderful in that their simplicity means that they run a long time, and don't seem to really 'break'- too rugged or over-engineered! They get dirty and slow down or jam, but I have never heard of very many actually 'wearing out'!
