BUSA does not dispute all the previous repairs, and yes, I've got all the certificates and paperwork from the original purchase and the repairs.
Progress report: I dug up an email address for Breitling in Grenchen (from this forum - nice!) and wrote them today. With any luck, they'll take the watch and fix it right. Looking through other posts here, it seems I'm not the first to have problems with BUSA repairs.
BUSA did send me pics - link
here. They show the second hand touching the minute hand at the 10 o'clock position, which I guess could have initially caused the problem. But now the flyback returns to 10 regardless of the position of the other hands.
Stay tuned. I'm thinking happy thoughts.
