According to Hachel, and always in accordance with logic, with truth, and with the equations of Poincaré, who was not weak in mathematics, the notion of simultaneity is invariant by change of observer JOINT at the moment of measurement, what varies for them is the INTERNAL CHRONOTROPY, and not the notion of simultaneity.

  And whatever you say - Poincare had enough wit
to understand how idiotic rejecting Euclid
would be, and he has written it clearly
enough for anyone able to read (even if not
clearly enough for you, poor stinker).
 

Actually Poincare did and assumed a four dimensional 'curved' spacetime, from which Euclid's three-dimensional space is a 'sub-chapter'.
This euclidean space is kind of projection into the realm of the local observer, who 'cuts' spacetime into time and space, simply by being somewhere.
This is a very different concept than the usual mainstream interpretation and actually different to the interpretation of Einstein in his 1905 paper, too.
Poincare's idea was further developed by Hermann Minkowski.
So Poincare's relativity is different to Einstein's, which was mainly based on Hendrik Lorentz and his 'Lorentz transform'.
But Poincare regarded this concept of Lorentz as wrong (even if he invented the name 'Lorentz transform').
