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.

Ah, but here is my explanation! Thank you sir!
There is a one-second time difference between 00:00:08 and 00:00:07", between my watch and the watch on the moon.
This is because of the speed of light, which is quite slow, and takes at least a second to reach me.
And so that explains everything.
It's magnificent, I understand better.
Here it is, my explanation.
I am infinitely grateful to you... So that was it!
