 Clocks are physical devices (except in Wozniak's mind). They are not
synchronized by imaginary devices on imaginary spatial dimensions.
 They are built in order to have the same rate (inside an acceptable
narrow interval) to begin with, then drifted according to what
General Relativity predict in order to stay in synch in ECI
frame (despite what demented Wozniak pretends).
 These are engineering tasks, not the stupid mythomaniac fantasies of
a histrionic senile country doctor.
 But you're mixing everything up.
 That's not what I'm talking about, I'm talking about the initial synchronization. At some point you have to synchronize all the watches in all the capitals with each other.
This is the problem Poincaré wanted to solve. In order to syncronize the
clocks you must first find out what it means to synchronize. Earlier the
best way was to carry clocks and that was good enough for many purposes.
But with telegraph a greater accuracy became both possible and necessary,
and that meant that the concept of syncronization had to be rethough.

However, this is by nature impossible.
It is not impossible. One just must know what one needs.

The notion of universal anisochrony means that each watch will lag behind the other with an anisochrony Et=x/c, a reciprocal phenomenon that will affect all the watches in the universe.
No, it does not. A watch may be set to show that time or another time and
it shows as it was set.
