Vintage Digital Casio Clean & Service

In this video I take a Casio 31QS-11 from circa 1978 that has had battery leak damage, clean all the components and get it running again. I show you all the tools and equipment I use to perform this task.

If my videos have helped or inspired you into this hobby then I would be grateful if you could support the channel. A little goes a long way.


Thank you for your support.

I actually have one of these. It was my first watch I had not counting a few children watches. It's from 1977 and if I remember right I got it from my parents when I turned 13. I just found it again a few months ago. Put a battery in it and it runs nicely. The bracelet was long gone but I maned to find an original Casio from the same time era on a flea market the other day. I've been wearing it for a few days and I feel like a kid again. ;)

I started my love of watches with digital in the 80s my grandfather taught me how to fix them. My prize watch played The Yellow Rose of Texas. I miss those cool digital watches that did all those things that at the time were simply amazing. I remember a guy from church showed me his new watch it had a thermometer on it, man I thought that was the coolest watch ever. It was a Casio I believe.

Great instructional video Michael. I am just starting to look at a couple of old LCD watches so this provided me with a great inspiration. I was in electronics assembly for 20 years so should help.

Hi, I am currently rebuilding one similar to this module making one out of two, they are a right PITA to set the time and date took me ages as well to figure it out but got there eventually. Enjoying your video's and plan to watch more of them. Keep up the great work.

Another great video. I find using a "sticky ball" to remove the case back removes the risk of scratching it with the slip of a metal tool.

Brilliant.!If I remember the boxes flashing under the days of the week were an alarm function for each day? Don't hold me to that but took me back eon, s. Happy schooldays! Cheers.

Mike, to repair the battery contact where the plating has come off, try using the conductive paint that is used to repair broken contacts on car rear demisters.

But how to set it to normal time, not that am/pm stuff, it always took ages to get that out, and have the normal display instead of the weird yank settings..
