I've got this Tissot SeaStar with 8980/990 marked on the back-plate.

Unfortunately, there is no battery. Can anybody help me to get knowledge about the correct battery so I can buy a new battery?

Alternativle find the makers mark and caliber number of the movement and post it on the site or a good clear close up of the movement.

It looks like a ETA movement I just don't recognize the number right off the top of my head. I circled in the picture where the number should be

Thank you very much.

I have measure the battery housing to 9,5x2mm (9,5 was acually also printed on the batterycontact) - and by looking up in https://www.watchbattery.co.uk/Replace-Battery-Find-Battery.shtml i found the battery to be 370 or 371, which seems to be equivalent.

I have difficulties ies to read the eta-number, but it looks like 955 414  - and a search reveals  movements that looks similar to mine. They also seems to use battery 370.

 

Thank you very much for your help.

Thank you for the service sheet. Fortunately, that watch started up as soon as I added a new battery. I think I will have to practice before I can use all the information in the datasheet.

    • Regarding the spring winders, I made my own and used copper pipe reducers as the tubes to retain the spring. You will need to cut out a section for the end of the spring to protrude but if you watch one of the many videos on this subject that will make sense. You can find a selection of sizes on Ebay for very little cost. I'll attach a pic showing one of mine.  Good luck!
    • There were things bothering me about this discussion that took me a while to figure out the problem. In the image below it appears to be the spring may be pushing up? Normally when Omega has a spring pushing up the pinion has a pivot with a bridge to hold it in place so in other words the spring can push on something that stationary as opposed to this which appears to be floating? To understand the problem with the above image we need another image of side view which I have below. In my image down below on the left-hand side it agrees with the image up above. But the only problem is the left-hand side is defective and the right-hand side image is the way it's supposed to look. Then Omega if you can access the right documents does explain how and why this problem occurs. With the pinion floating around it might be assumed that you support it when putting on all the hands but you do not because as noted below if you do this small bush on the pinion will relocate out of position exactly what we see in the image up above.   Then Omega does not mention this but there is a possibility of also damaging the pinion and causing the bush to move to where it's not supposed to be when removing the hands.   
    • Maybe show us 1) the watch, 2) timegrapher readings in DU, DD, PU, and PD.
    • The timegrapher displays significant beat error variations in the dial-up position. When the watch is lying flat (face up), the beat error is much higher than in other positions. Beat error readings are inconsistent, with especially large gaps in the face-up position.  Please help !
