Hand movement and stopper.
Please note that each watch includes a small plastic stopper by the crown. This plastic stopper disconnects the hands of the watch; this is to increase the longevity of the battery whilst unused.
When the stopper is in place and the crown outward, there is a small movement of the minute hand when shaken. This is not a fault with the watch and you should find that once the stopper has been removed and the crown pushed into the watch the hands reconnect and are held firm into place.
