Maybe ask Sora to send you the working movement only (as a spare part), and have it replaced at the local watchsmith?
I had a similar situation with my TD (a nice lady who is not a TD here) buying Tag day date. The watch was not winding properly - the rotor stuck and the crown too. I sent it back for repair. The watch arrived after almost 2 months but was still deffective - the minute hand was loose and the rotor still didn't wind the watch properly.
I just ask her for a refund because I didn't want to spend another 2 month waiting for unpredictable. She said yes, no problem, please send it back to me.
Finally I chose another watch so the refund wasn't necessary.
And this is how the TD should perform IMO.
