There seems to be some problems in the chronograph function of my Longines. I bought my watch about two months ago, and this morning, while measuring time, I noticed that the minute-hand of the chronograph was stuck in 11min position. I reseted and restarted it just to notice that this time it was stuck in 1min position each time I tried it. I called my AD and they promised to send it in to warranty service as soon as I bring them my watch. However, for the last two hours the chronograph has worked well without any problems, no matter how long I keep it running or how often I restart it etc.
So what should I do? Does anyone have a clue what could be the reason for the problems? Should I send it in anyway, even though everything seems to work well again?
Thank you in advance.
