there is no difference, even tha equations are tha same

The Weyl tensor turns out to be analogous in many
ways to the electromagnetic field tensor, which you
can think of as an antisymmetric four by four matrix
(6 algebraically independent components at each event).
With respect to the world line of a given observer, the
electromagnetic field tensor decomposes into two vectors,
the electric and magnetic field vectors (3 components each).

and if you put a mechanical watch close to a magnet, he
will tick slower

Like a Pound-Snider experiment except louder.
