Battery for a ESA 942.711 lcd watch

[rogart63]

Bought a cheap  Certina Chronoolympic lcd on auction. Am a  little tired in my head? Can't find what battery it should have. Need to buy some and see if it works?

If it's the one that takes 2 batteries I think they are size 392

Ordered. Fingers crossed that it will work  

Maybe it should be ETA 942.711 as i didn't find anything on ESA ?

SR41 is a 392 battery as in picture, remember to put them in the correct way as in picture.

I just put esa 942 711 into google images to get picture.

The seller told me had tested the watch with some batteries. He said it didn't work.Can hope he did set them the wrong way. And when i put them in the right  Let there be light. If not i have a NOS i can buy. 

Maybe i should take a look under the circuit tomorrow. Before i smack the batteries in.

Hope he hasn't put them wrong way and blown the circuit!!

 didn't work? But watch watch nice. So i will try to find a new circuit for it. The lcd was working but lots of numbers was missing. Tried to clean the strips on the lcd screen but didn't help. Or a complete movement will be better?

Sorry to bring up an old thread. Did you end up getting it all sorted?

Great stuff. Iv'e got a Longines one that isn't working either. Thought it might of been an easy fix until I removed the black plastic cover and saw this...

Maybe you could try using conductive paint on that? Have you tried to clean it with isopropanol?

I have cleaned it up and Iv'e used conductive paint to to re do the corroded parts, with no luck  I hope its not the IC (Think that's what it's called) I will start a new thread about it.
