  I use the observation, that clocks around the Earth surface tick at the same rate, while they don't tick at the same rate at different altitudes.

There is already a bias here.
If a watch is placed at altitude, it does not evolve at the same speed as a fixed watch placed at the level of our local mass reference center that we could put the sun, or even the galactic center. The effects of these reference frames are perhaps negligible. I do not know. But at least, the effects of the revolution of the object around the center of the earth are not the same as the effects
on an object placed on the surface of the ground. Worse, for the object placed on the surface of the ground, it is the center of the earth that rotates around it; and also for the other. These effects are no longer really Galilean, but effects of rotating reference frames for which I have given the equations, and which cause some surprises (it is the object that goes the fastest that has the time that passes the fastest, contrary to Galilean effects).
