Pictures please

 

Ok. We will telepathically work out which particular late 70s Seamaster quartz model you are talking about, out of the dozens that it could be.

Then we will research the availability of movement parts or replacement movements for you and provide all the information for free and without thanks.

Or, if you think we might not be able to do that, you could post some pictures so we can start to identify the model. You might also want to consider being a little less dismissive of people from whom you are asking for help.

 

This is why I switched from quartz watches to mechanical ones years ago. I got tired of spending money for watches from seemingly decent brands that ended up useless. It's a sign of our disposible society.

Only suggestion I have is to open up the watch, get the caliber (model) number of the movement and try to pick up a working version that uses the same movement for cheap on eBay. Once you do this, it is a simple matter for a watchmaker to perform the transplant.

You have to make sure you get exactly the right caliber movement, or it may not fit.

Best we can do without pictures.
