solar battery replacement of a Seiko watch

[@jamesmeap9093]

Thanks for the video. I've never opened my solar watch, it's always helpful to see it done before attempting. I will say though, for anyone attempting to work on any quartz watch, be careful not to touch the copper coil. Over time, oils from your fingers can cause premature corrosion to the coil, necessitating a replacement. I'm not saying you touched it, but it may not be clear to a first time do-it-yourselfer. Great camera work too!

I respect the ingenuity for improv skills. I'd like to note that the tool to remove these battery covers are like 8 bucks. Just got one and took about 5minute max to fit the tool to size and twist the cap off. Thank you so much for showing the actual process of replacing the battery too! I was very concerned I'd break something 😅

I have the same tools. They have taken the back off many watches, but not this one, just could not get enough torque through the small pins. If the normal tools do work then yes it is better option. This is not a preferred method of removing watch backs, more of a method of last resort. The back had been on for 15 years, grease hardened and the case on really tight. If you look carefully at the video even with big spanner it still required a lot of effort to release it. I do say out start if you can remove with usual tools jump to 7 minutes in.

@@dodeedo oh man I never considered it could be just shut down that hard due to age. The more we know and ill remember this technique if that ever becomes the same scenario. Thanks for the response back btw.

Thanks for the demo! One store quoted me $70 to change the battery. After seeing this video,I think I'll do it myself if I can open it!

[@dodeedo]

Please see my other video on getting the back off. When I did mine the usual tools didn’t work. Hence the need for big nut

[@dhruvd8953]

Can you please share the brand name of the battery that you used. My seiko Solar is lying idle for three years now because I can’t find its battery.

[@dodeedo]

If you get it out you can see what is on it. I think I may have purchased a Seiko brand. Just check if it has the tab or not. I did find battery info on Google from the movement number on the back of the watch

[@akorejepade1261]

Where do you get the replacement battery from?

[@dodeedo]

I got it from eBay. Found other on line battery specialists as well. Seems like there are two versions. My watch needed the one with the tab

Is this a joke?

[@dodeedo]

No, just a solution to real problem, if you can get the back off with normal tools then great otherwise this is my solution to replacing the battery after 15 years
