 It's not up to me to explain, but up to you to understand what's going on.

And how can I understand what's going on when the only person in
the universe who knows will not explain what's going on?
It is up to you to explain the abnormal things you claim.

First, let's not talk about gravitational shift towards blue, red, etc., these are notions of general relativity, and it's already complicated enough to have a serious dialogue with just a very simple notion of SR.
So you have to explain this strange fact.
I admit that the moon is exactly 3.10^8m away (a little closer than in reality for a simple measurement).
I set the two watches in absolutely identical ways, and I sent one to the moon, after a three-week trip in order to have a speed that is not very important compared to c and therefore (1-v²/c² ~1).

Why do your repeat this?
We agree that the clock at your table and the lunar clock
still are synchronous after the latter clock has been
moved very slowly to the Moon.

Something is going to get strange.
The watches are going to get out of sync. I notice that they always beat at the same time and that the chronotropy is not altered,
but yet, when my watch shows 00:00'08" the lunar clock shows, at the same time, 00:00'07".

This is the very point.
Why do you guess that if you look at the lunar clock with
a telescope (something you haven't done) then you would see
that it lagged 1 second on the clock at your table?
Remember, only you know what's going on, so you better explain.

This is frankly abnormal, and we are in the same hypothesis as Römer, observing the moons of Jupiter, and noticing abnormal things.

Why do you say that Römer noticed abnormal things?
Römer noticed that the visually observed time Io was eclipsed by
Jupiter varied with the time of the year. And since the orbital time
of Io was supposed to be constant, this variation could only
be explained by that the speed of light is finite.
When the distance to Jupiter was increasing, the distance to Jupiter
was shorter when the eclipse started, than it was when it ended,
and the eclipse would be seen to last a bit longer than average.
When the distance to Jupiter was decreasing, the opposite would happen.
This made it possible for Römer to estimate the speed of light.
That the speed of light is finite is hardly "abnormal things".

What is needed is to explain things, and for that, it takes a genius greater than that of Römer who gave an explanation that, later, will probably make people laugh when we really understand the theory of relativity.

Yes, that is my very point.
You are the genius claiming abnormal things, and it is the genius'
responsibility to _explain_ these abnormal things.
So please explain!

The question remains: What is happening with my two watches? Why do they no longer show the same time?

Why indeed.
Römer's conclusion "the speed of light is finite" was based
on measurements.
You have never observed the lunar clock in a telescope.
So the first point you have to clear up, is:
Why do you _guess_ that if you look at the lunar clock with
a telescope, then you would see that it lagged 1 second on
the clock at your table?
When you have explained this, we can take it from there.
