Seiko dive watch - s/n 530687 8123-7190
What battery does this watch take?
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.

Do not test a Seiko Kinetic Capacitor with a battery tester
The Seiko Kinetic watches use a Capacitor (rechargeable battery) that costs
between 16 and 30 dollars.)
They drain drastically if they are tested using a typical battery tester using 2 prongs to get a reading. It shortens the life of a capacitor significantly.
Don't ruin a good capacitor by testing it with a battery tester.
You already know if it is doing the "2 second Tango" the capacitor is depleted and needs replacement.
A lot of Kinetics sold used will tick when worn and a little while after being taken off the wrist, but then stop.
Those are depleted capacitors, that need to be replaced.
If it is a 10 second Indicator swing replace the capacitor within a few weeks.
A 20 second swing is good for months in most modern Kinetics.
The Kinetic capacitor will not be at full charge when first installed.
Either wear the watch you installed the new capacitor in for a few days,
or put it on an electric toothbrush charger for a few hours, and it will reach maximum charge.
