Paul,

I noticed that expensive watch manufacturers never say in their
advertisement anything about accuracy:-)
(Which means that you can buy a $10,000 watch, it will go with
accuracy of $100 watch, and you cannot even complain:-)
I suppose that accuracy is not an important consideration for people
who buy $10,000 wrist watch:-)

And finding any such data on those expensive watches is
really hard.
I know that relatively recently a new type of escapement was invented,
it is called "co-axial" and it is claimed that it is comparable
or even better than the real chronometer (detent) escapement, but can be
used
in a wrist watch. Apparently only one watch manufacturer uses this
new escapement, and this is Omega. The word "co-axial" ust be written
on the dial.
I wonder whether these Omega co-axial outperform marine chronometers
or not. Unfortunately, the cheapest of them
are sold at a higher price then chronometers.

Concerning inscriptions on the watch "Chronometer", the Swiss
have some testing procedure, which legally allows having this
inscription. As I understand this testing procedure has little
in common with real chronometers testing.

Alex.
