Everything else aside, join date for RWI, I won't talk about that.
Sending your watch back is never reccomended, but ok, it's sent.
If you read and do research it is often months before the watch is fixed and resent to you. That is the general experience.
When I sent back my Panerai 1055, it took a full 3 months to be fixed.
So 1 week is nothing. What do you expect?
Even for gen watches it takes minimum 6 weeks for turnaround for stuff to be fixed.
You are asking for better service from a fake chinese watch underground dealer than real, luxury watches costing 15x as much.
Set your expectations correctly. And now you know.
