This watch is a hybrid ETA movement. It has a battery and a quartz and mechanical movement. It has been cleaned and runs fine until it is worn or moved around, then it stops or loses time. Position seems to affect it. I left it dial down overnight, and it lost an hour and a half. If this were a pure mechanical watch I would question the balance staff. But I really don't know what to thing about this type of movement.

Jerry you may be able to replace the movement is there a number on the movement some of the supply houses may have a movement,sometimes the battery clip will be loose and not make good contact...
