It is impossible to synchronize two watches A and B located in
different places.

So you agree that Paul B. Andersen's prodedure is doable and achieves
what you call "impssible".

You have to understand the words and concepts, and in relativistic

If you consider "doable" as I used it in my response then I may clarify
that nothing is doable if it is not clear from the specification what
the intended action should be. But as far as I can see there is nothing
in that procedure that could be regarded as "poorly understood".

 Yes, and not just doable, routinely done in billionfold.
All clock comparisons between all standard clocks world-wide
(which is needed to establish TAI)
is done by exchanging signals through the GPS system,
taking travel times of signals into account of course,

Until recently Richard "Lengrand" Hachel actually believed that
GPS receivers contain an atomic clock (maybe he still does), go
figure! He's still convinced that GPS satellites clocks are
synchronized against an infinitely far imaginary clock on a
fourth spatial dimension.
