Yep, that was a very good point. :)

With cars at least, there is a good argument for that. Look at taxis,
the reason those things keep going forever is because they are
generally ran three shifts and rarely ever cool down. Byweekly oil
change also helps.
However, it is an entirely different thing to lubricate a combustion
engine with it's high pressures and speed of parts and to lubricate a
watch which is lazy at best in comparison.
The idle speed of a 28,800 beat(480bpm) watch should be about 50 beats
per minute based on the 600RPM for the average six with it's 6000RPM
Hm, maybe we should design a watch that will idle when not in use ?
It would run for 10-12 days without a wind, but i guess the cannon
pinion and crown wear would be unacceptable.. ;-)
