·I have a Speedmaster Mk II that had same symptom before the (reset to 12 o'clock) pusher just fell out altogether yesterday. Still well under warranty it's going to the AD today to be sent for (hopefully) warranty service at the Omega service center.
. They did however perform a water resistance service and replace the crown, seals and the hesalite crystal (which I thought was odd), and it appears to have passed their tests. I’m a bit disappointed, but I don’t really want to send it back for another 7 weeks, so Ill get over it.
