Looking at descriptions of pocket watches, every now and then I see a watch that says
that the main gear is made of gold or even that the entire gear train is gold.

2) Gold is a soft metal, so I find it surprising that it would be used for a gear.
Maybe this line of discussion belongs on the watchmaking forum?
3) Gold won't rust or corrode -- this would be its big virtue aside from the
So I may be all wet -- but would like to hear what those in the know have to say.
