Right, but you know how fast the message was going, so you can compute when
he receives your message.  What does it say on your watch at that time?
Regardless of what it says on his watch, or when you would see him receive
it.

So at 215PM by his wristwatch he gets your message and sends it right back

Wouldn't time dilate in the other direction for you, relative to him,
because he underwent acceleration while you did not?  It's a classic
experiment that he can later return to you and his clock will be
permanently behind yours.
