My watch is stuck in the UK. Track&Trace is saying two "failed delivery attempts" for a week now. Hopefully its not going back to China now...
Sometimes qc pics end up in your spam folder. So you did not answer within the 24 hour mark.
As for the 243, they are no longer being produced. Maybe some dealers have a few left...
