I'm newly registered, and need help in figuring out the battery that goes with two of my seiko quartz watches inherited from my father. If someone could help me, I would be grateful . . .
The first just says seiko quartz with 4004 beneath it. At the bottom (6 o'clock position) are in tiny print: Japan 0903 - 8089T. This watch has a convenient battery hatch on the back.
2nd watch says Seiko quartz Sports 100. Tiny print at 6 o'clock: Japan 8229 - 60ILT (the I may actually be a numeral "1").
