The very word 'relativity' requires mutually symmetric perspectives.

 Absolutely.
 

Since both perspectives are of equal rights, we need to accept both views as valid, hence need mutually symmetric perspectives.

 Magnifico! Wunderschön !!!
 

Thanks.
 But this is obvious and certainly not disputed.
 But Einstein, however, had not written about a symmetric system of clock synchronization.

If clock A is synchronized to clock B according to Einstein's creterion
the clock B is synchronized to clock A. Although the procedure is not
quite symmetric the synchronity defined by it is.

Instead he used something, one could call 'external time' (kind of 'true time').

He ded not use what cannot be used.
