A good idea?
The excentric automatic-winding weights in wristwatches were originally mounted in plain bushings, but these wear and the weight ends up scraping against the plates, or the casing.
Rolex had a "good idea", and pots of money, so they mounted theirs in a stonking ruby. Looks really good, but if you drop the watch hard the ruby breaks into a thousand pieces, while the watch keeps running for up to 30 hours. Aie!
Seiko had a better idea, mounted theirs on a ball-bearing, with the geometrical minimum of 5 balls. And just where did they get a cheap and plentiful supply of 0.7mm tungsten carbide spheres? I'll let you guess, next time you write you probably have one close at hand...
