when making a clock should remember when having to change the battery don't mess with the hands..After installing a new battery the hands will automatically go to 12 and stop. Then in a few minutes the hands will start moving again sometimes a full 12 hours without stopping then will stop on the right time. And sometimes they will start again and go directly to the right time..Its good to maybe add a little glue on each corner of the movement for when changing the battery if the movement slips the hands will be off a tad..and like always the movement will advance an hour in spring and fall back in the winter without little hands helping so don't touch the hands... Dave, I'm talking to you!?!?!?
