Worried

Sent this watch back a few weeks ago because the Crown (Setting Stem) would pop out inadvertently and cause the watch to stop running. I would look down and realize the watch was stopped. Sometimes the stem had popped out one click and other times two clicks. Watch was returned to me and they said they had replaced the movement and I assumed that the watch was in excellent condition... however shortly after I started wearing the watch again the Crown stem started popping out again. I called repair and spoke with the lady there and was interrogated as to what I must be doing wrong (ie, allowing watch to snag on clothing, extreme activity/movements etc) which I have done nothing unusual in the wearing of the watch. (I have another Citizen Titanium Solar purchased in 1998 worn every day and never been serviced yet, looks mint and keeps great time) so I know I have done nothing wrong with this watch. This Grand Complication does not have a "screw down Crown" so I can only imagine it is a manufacturer's design flaw or something of that nature. I returned the watch again and it has been received by repair so I am hoping the problem can be resolved this time as I have really bragged on Citizen Watches since 1998 and assumed all Citizens were of an equal quality to my 21 year old one. I would prefer to be able to do that about this watch.
