Hi Erwin,
No that observation has never happened to me. One or two watches purchased years ago refused to work at all when I got them.

Never mind, that's all part of a watch obsessed life I guess.
Perhaps you are right in believing the watch might take some time to get used to you. It could be that you don't do as much arm waiving as some, and perhaps the power reserve takes a bit of time to get up to its high point

(only joking).
My beloved used to believe that the electrical energy in her body was responsible for slowing her Omega Deville quartz, to the point that she had it duct taped up so it kept time.

All good though, as when it finally went to the great watch cemetery in the sky I bought her the mechanical version straight away. Fortunately, it has never let her down, run slow or stopped for no particular reason at all.
