[Solved] Seiko 0903 5019

Is the coil broken? Or the gear train needs some lubrication?

could be any number of things, but i would say it probably will need cleaning and lubrication on top of whatever it has wrong with it, you could probably get a donor movement from ebay to trial and error the parts. the coil you could do a continuity test.

it looks pretty clean/ has no dead battery juice.

I was shocked because this movement have 3 languages on the day-disk, common one should be 2.

 

Thanks Rodders for the manual.

I'll be working thru the tests and servicing in the next few weeks as I equip my workspace.

I've got a list of kit I want get, preferably used and cheaper than new, from some youtube videos.

 

It is fun to play but realistically that is an inexpensive movement.

i myself have worked on inexpensive movements purely for the sentimental value, in fact that was what started me on my watchmaking jorney
