OK. Thanks for a clear answer.

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.

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.

I synchronise my clock to the master clock with this:

It uses the internet. The delay both ways in the net is measured

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"

How did you read "the abstract virtual clock"? :-D

This means that in fact, all the watches remain out of tune by nature,

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?

Well that's ignorant, both Big Bang and Steady State
are neither falsifiable, neither "scientific",
both merely exercises in tuning, furthermore
now it's stopped.
The JWST has roundly paint-canned expansion theory
and most of inflationary theory since it was already
for decades and decades that astronomy just has
only one variable "redshift" that redshift bias
is removable because of optical effects and now
all the old Cold Lambda have a sort of speculative
way of reading them.
