What happens if I set two identical watches (same chronotropy) on my table and I slowly move one of them towards the moon
(let's say in three weeks to avoid a v²/c² ratio very different from 1)?
So the two clocks on your desk are synchronous.
If we ignore the gravitational blue shift, and pretend that
the ECI frame is a true inertial frame, then the lunar clock will
lag 0.45 μs on the Earth clock.
Which we will ignore, as you said we should.
So we will consider the clocks to be synchronous (within 1 μs).

I notice in my telescope that when my watch marks
00:00'08" the lunar clock is desynchronized and marks 00:00'07".
Don't be ridiculous.
In the telescope you will see the clock showing 00:00'06.72".
Unless you are a complete moron, you will understand that
the lunar clock must have advanced 1.28" since the light
you see in the telescope was emitted.
So the clock is really 00:00'06.72" + 1.28" = 00:00'08".
The clocks are still synchronous.
Which is blazingly obvious, so what is the point
with the nonsense below?
Totally correct.
But why didn't Einstein do this nor even mentioned it in his 1905 paper?
