Where should I go to have the battery changed on my GS 9F?

My GS 9F is in need of a new battery. Is it so specialized I should take it to the AD, which will charge $50 (includes pressure test), or can I just go to any watchmaker?

I don't have an answer, but $50 with a pressure test doesn't sound like a bad idea! They would probably charge nearly that much for the pressure test alone.

Any watchmaker will do it, but I always go to the Seiko Service Centre as it's not too far away and is a walk-in/while-you-wait job and I get an 'official' paper and pressure test printed readout to stash with the watch box and papers (and it's only $40 here). One thing to make sure is that a non-Seiko watchmaker uses the correct Seiko battery, which is a particular type made only by them (but easy to find on eBay).

I have the tools to do it myself (and there are 9F changes on YouTube if you need a walk though), and I have removed dozens of vintage Seiko casebacks for inspection, but the new ones seem tighter and I don't want to end up with a scratched caseback like I did with my new 2018 Turtle.

Out of curiosity, how old is the battery/watch?
I was wondering how long it lasted.

The GS 9F I bought new in Japan lasted exactly three years from the month of the production (per serial number) July 2017-July 2020. They changed it free as the three-year warranty started in Feb 2018 and I had the card with me.

All others I changed before required when bought used (one was doing the double-tick alert when I received it).

For mine I take it back to my AD. They can do it in house with factory batteries and gaskets as well as pressure test when done. As many as I have purchased from them it's complimentary.

I can also send it to seiko for $50. They do the same thing plus adjust the timing if off. Not a bad deal.

I just changed the battery on my SBGT235 for the first time. I used a friction ball to remove the caseback. The original battery lasted 3 years and 3 months. The battery just pops out when you pry underneath of it a little bit. I used plastic tweezers to do this. And when installing the new battery, it has to be angled in a certain way and then it goes in easily. At first it was not going in when I was pushing it down, but then I looked at how it was held in place and saw how it needed to be angled in order to be installed. Now my watch is running again, and I should be good for another 3 years or so. And I also greased the gasket. Here is a picture of the movement before I reassembled it.

If you bought a Rolex you didn't had this problem.




I hope people take this no too serious ofcourse

IMO...i'd probably just send it to Seiko just to be safe.

Good job. Thanks for the pic - now I know what my SBGT235 looks like inside

I thought you might like this picture. And here is the package from the battery I used as the replacement. It is made by Seiko.
