I was told that after the battery is replaced in a Perpetual Calendar that it will no longer click in one second increments, but only in 5 second increments. Why does this happen?

A Seiko Perpetual Calendar with an improperly installed battery will click in 5 second increments. We can install the battery properly and re-program the watch so it will tick in one second increments.

My Seiko Perpetual Calendar watch had the battery changed incorrectly. The battery is still in the watch. Can you reuse this new battery?
