I just purchased a Laco Flieger B-Dial ETA2824-2. The watch looks great, but if I shake it I can hear the movement clanking around in the housing. It almost feels like a toy watch with a loosely assembled internals? Obviously I don't shake it all the time, but even when on my wrist if I move my arm "quickly" like to open a door or something I can hear the movement on the inside rattle around. Is this normal?
