The links were not meant to be the best material on tourbillons, but
provided as background, since they were readily available on the
internet.
As I've already mentioned, since the mechanism by which tourbillons
work is not a mystery, but is readily explained in terms of the laws of
physics, it is easy to see how they help a pocket watch, but not a
wristwatch. So, just as I'm not inclined to humor someone
who claims they have invented a perpetual motion machine, I'm not
inclined to humor anyone who believes a tourbillon is useful for a
wristwatch.
The fact that Patek has made tourbillons for their time trial watches
does not mean the tourbillon had anything to do with making the watch
accurate. I have a Patek 3970 which has no tourbillon, and yet it
is so incredibly accurate that it gains no more than a few seconds
every 6 months when I reset it for daylight savings time. Is this
a fluke. Perhaps, but my 5970 with the same non-tourbillon
movement gains at most 2 seconds per month.
Yes, this can be discussed on another thread now that I've responded.
