Watch battery clamp spring to hold battery into place for the ETA 976.001 Swiss watch movement. Experience has shown the battery spring within this movement easily flies off when trying to install a new battery; the battery holder spring is needed to hold down the battery so that the ETA 976.001 movement will work because without this key part the movement will not run. This spring is specifically designed for the ETA 976.001 and it will not work with any other movement.
