●When replacing the battery, we recommend that you contact an AUTHORIZED SEIKO SERVICE CENTER. In that case, after every battery change, a new “●” mark will be inscribed on the case back at the position corresponding to the next battery replacement time. Be sure to check the mark before using your watch again.
