Citizen 2851A quartz divers watch

[AFV]

Hi I’m new here and wondering if someone can either advise me on the correct installation of these keyless works components or guide to where I can find support information. I cannot find a schematic on the movement. Details are Citizen GN-4-S, 35-5011, 2851-262981 Y, 3100079.

Im not sure how the brass coloured piece fits. Refer attachment.

thank you

Allan

Here are the details for another 28 Series movement which may help show you where the unlocking lever fits.

Did you take it apart and do you have any photos?

Hi AndyGSi

thank you for the link

yes I’ve dismantled it as someone just over oiled it or just hit it with WD40??

it runs but day jumper sticking (from oil!), so I’m giving it a good clean and light oil ( in the right places) with new battery. I will attach a few dismantling photos.

I hadn't realised this morning that the document did cover the 2851.

Well centralising the rotor to refit the train wheel bridge is a problem as it always cocks to one side. After many attempts the rotor went flying and I’m up for another magnet search tomorrow!!

any trip to do this? Saw a comment about placing a magnet underneath the plate?

Hi. It is feasible to put a magnet under the watch to stabilise the rotor  I believe it was Hector who first tried this out and was sucessfull

I think this is the crown you need.
