How to dismantle and repair SEIKO 8F56-0020 watch key mechanismus


Recommended Posts

Hello,

I am living in Brasil and I  bought the SEIKO Perpetual Calendar watch 8F56-0020 about 20 years ago outside Brasil

in Amsterdam Airpofrt,Netherlands.

The watch kept running very well but last few days after changing the battery the key mechanismus started to fail

to work properly. It does not arret at positions 1 and 2 as well and thus it makes the problem with electrical contacs

which depend on key positions. As in Brasil does not exist Seiko repair shop I do not now where the watch

could be repaired.  Maybe I have to send it to some Japanese repairing service ?

Please  can somebody help me with this problem.

Thank you

you should really go to the Seiko Japanese site Lookup servicing information and don't take you to the nearest service center. Unfortunately they know where I live and keep sending me to the US service center which isn't helpful

https://www.seikoserviceusa.com/

but either always reach out to them and asked them if they had service it. Unfortunately it's a complicated watch and nothing lasts forever so it would need to be serviced eventually. Note regarding complicated I found the service manual for it would not recommend anybody doing it it requires special tools but just in case you're curious as to what's inside your watch there is the service manual

    • Hello good watch folk ,I  just fancied a light hearted discussion after my head was starting to spin over Epilame 😅. Specifically I'm meaning the sale of vintage watches, say nothing past the 1980s market. The stuff we see on ebay and other similar sites and found at carboots, curio shops etc. And are  we thinking its reaching a peak volume ?  Younger generations clearing out passed parents and grandparents possessions.  The younger folk are not as sentimental as the old fogies ( I'm now nearly at an age that i used to think was old fogie age ). When might it have started ?  i often wish i discovered the hobby much much sooner when selling your grandfathers pocket watch at a boot sale for a few quid was just a way to offload some tat. And when might it slow down. Thoughts anyone ?
    • Yes i did eventually realise that the oil will act as a barrier, I'm sure the discussion will continue. Ive had two oleophobic coffees ( added coconut ) and in the meantime i have this just delivered to take my mind off epilame for the time being. My favourite type of dial, its a beautiful looking watch traditional English made and it runs,  the ticktock is phenomenal,  i can hear it across my living room .  You wont believe how much it was. Thats interesting about synthetic oils , i thought the same, going from a 2 year service to 5 years is a big drop in income for service folk.  I expect some did well when they embraced the use of synthetic,  probably drawing in more customers than those that didn't use the new fangled substances , i bet fairly short lived though. The more frequent service makes more sense to me, not for just the service but for the regular check up inspections that might pick up impending faults. As far as epilame goes, wouldn't it be great to be able to fumigate the complete movement in a sealed jar of heated stearic acid, 🤔 now theres a thought 😅.
    • Imm going to close the discussion by attaching the photo of my super-titanium after several vicissitudes finally working. Purchased as not working I replaced the battery and for a stroke of luck I found its semi-new solar panel which, having verified its operation, seems to recharge the accumulator perfectly. I had taken this watch almost by bet, with 40 euros I brought it back to life. The initial half idea was to resell it to finance another purchase, but.. it's definitely a nice item. It would need to check the impermeability but it's a pleasure to see it on the wrist 😃
    • In fact the secret is to go gently and find the way without forcing, and the movement enters without problems
    • Yea a have given it a full service this movement is chinese 2813 whats the lift angle for this movement does anyone knows  and how  do a remove the default  of 52 degrees on my timegrapher?   Hi you said my lift angle is default how do a remove this from my timegrapher?
