 Considering that transactions are instantaneous,
why do you say that the picture you see in the telescope
is 00:00'07, when it obviously should be 00:00'08" ?
 Please explain.

It's not up to me to explain, but up to you to understand what's going on.
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).
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 frankly abnormal, and we are in the same hypothesis as Römer, observing the moons of Jupiter, and noticing 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.
The question remains: What is happening with my two watches? Why do they no longer show the same time?
