 Everything you say is true.
 So I can answer "yes, absolutely" to all your questions.

OK. Thanks for a clear answer.
You expect your watch to be synchronous with the clock on the wall
of a railway station or an airport an airport within a minute or so.
That is because you know that just about all clocks in France
are synchronous and show UTC+1 hour.
So do the clocks in most western European countries,
Your clock and my clock are synchronous with UTC+1h.
(My clock within 1 second)

 The problem is that you do not understand what you are doing, and what a synchronization process consists of in our universe.

 When you synchronize all the users' watches, you synchronize them on a single watch, which is the system watch and which is located in a given place (the position of the watch is as crucial as its relative speed in the cosmos).

Quite.
The single clock is the USNO Master Clock.
Its position in cosmos is Washington, D.C., USA

This watch is an "abstract", virtual watch, which synchronizes all the watches on it, and on IT ALONE, to give coherence to the whole.

It is a very real clock, consisting of several atomic clocks.
Richard, I am in the real world.
I synchronise my clock to the master clock with this:
https://time.is/clock
It uses the internet. The delay both ways in the net is measured
and corrected for, so the displayed  time will be correct
within a second.
You answered yes to these questions:
Do you use the internet to set your watch?
Do you expect your watch to show the same as the clock on
the wall of a railway station or an airport (within a minute or so)?
So you synchronise your clock to UTC+1h in the same way as I do, and you
expect your clock to be synchronous with UTC+1h within a minute or so.
(I expect it to be synchronous within a second.)
So don't tell me that you used some "abstract virtual clock"
when you set your clock.
How did you read "the abstract virtual clock"? :-D

 This means that in fact, all the watches remain out of tune by nature, and will always remain so,

You have said that you use internet to synchronise your clock,
so what does it mean that it still is "out of tune"?
Is your clock a cuckoo clock with a cuckoo who is singing out of tune?
Merry Christmas Richard.
