Unfortunately, the Seiko website does not have a serial number lookup, so you'll have to identify the model. The "8123-7190" is what Seiko calls the "caliber code." Entering that on the page linked below will narrow down the model number list for you. Clicking on the link for your model will give you the instructions in PDF format. The instructions for your model tell you what size battery to use. For example, the manual for the 8F32 states on page 11 that the battery size for that model is CR2412. (Note - be sure to get the correct instructions; different models have different battery sizes.) "Automatic" Divers watches have no battery, they are powered by a spring mechanism.
As it is a dive watch , it will be sealed and that requires specialist tools to remove the back and new gaskets to reseal it
Take it to a jeweller for the job and save the watch

mcdevito75 here, Best Bet, you may need a special tool to remove and replace the SPRING BARS (PINS) that hold the band onto the watch, then you may even need new spring Bars, (pins) to re-attach the band to rthe watch. BEST BET, look for a small watch repair shop in your area to change the band.
