seiko 5856 regulation


Recommended Posts

Hello!

I have a 5856 that is losing time. I opened it to see if i could adjust it slightly, but i cant figure out which screw to turn, or if it is even possible on this movement. Can someone maybe point me to the right screw or tell me if i am wasting my time?

It probably needs a clean and lube. Check this for more info.

Does anyone have a King Seiko Caliber 5856 service manual? Or one for a similar reference? 

I have a King Seiko I'd like to clean up but I'm hesitant without a technical document. 

Thanks!

Mark or photograph the current position and then try. These trim capacitors typically can be rotated all way round and have one position for maximum capacitance. Either way you go from there will reduce the capacitance and speed up the watch.

This will regulate the timing. Servicing it will also help, the rotors can get quite clogged up with wear debris. The train wheels are very tiny so be careful, also the rotor can be a real shite to place back with being magnetic. They want to stick to everything and jump around. There is a little trick that helps with that though.

And what little trick might that be?

Seriously if you decide to strip down and service the movement i can talk you through it .

All of this is based on my hobbyist experience.  Seiko quartz of this era came pretty highly regulated.  They were designed in the mechanical watch era, with mechanical watch parts, and were meant to be serviced.  If it is loosing that much time, it needs a service.  I have serviced a few 754x movements that were loosing significant time.  Without adjusting the trimmer, they all came up keeping time within seconds a month after servicing. 

I would not touch that trimmer screw until you have serviced it.

    • Thanks John, that will surely be helpful when I get time to continue the reassembly, My watch is different in that it uses a thumb slider for start/stop instead of the crown.
    • I get that and you are right choosing a scope is not easy, I'm on with that at the moment and i wont go until i know i have it right. There is some very misleading info and video out there, my first big mistake came from just that. I would just hate to see any harm done when Alex made a simple boo boo. Anyway enough said lets us let this error disappear .
    • Sounds like they didn't open up the watch to assess it, just put it on a timegrapher. If they are going to say the warranty is void because of misuse/damage, showing case damage isn't sufficient.  I would want them to be specific about how the movement was damaged.  I'm never happy, but I try not to take it out on people who are trying to do good work 🙂 Cheers!
    • @Paul80, I've very much appreciate your posts.  Reviews of tools are very valuable, especially when one is taking a chance by buying from some place like AliExpress.   
    • We all do. I make plenty, but I try to correct them, and I appreciate it when I'm educated by others. These videos live forever,  very few are ever fixed. If someone is watching these for "entertainment", no harm done. If, however, they are like me, and trying to educate themselves, then watching a video that is supposedly for educational purposes and the information that is presented is wrong,  then I get really annoyed.  I spent a very long time trying to wade through all of the scattered and unhelpful info on these inspection scopes before I finally purchased one.  I was out of the electronics and electronics repair field before they were routinely used and available, so I had no experience with these types of microscopes.  Trying to figure out how the lenses all worked together to get  a certain level of magnification, field of view, and working distance was not easy. I think I got it right, but it took me *years* before I was ready to pull the trigger. I didn't have, and certainly don't have now, the kind of money where I can afford to make a mistake on an expensive piece of equipment like a good scope.  Muddying the waters is not helpful
