Hello everybody,

So I won a bidding war for a beautiful automatic Certina watch and I am super excited o receive it, I'm doing some research now but couldn't find any service manuals.

I'm very familiar with Seiko, Citizen watches and swiss made vintage watches but this movement looks really different to everything I'm used to and I don't want to screw things up.

The movement is Certina 919, the seller didn't include a photo of the movement but it's clearly running as you can tell from the position of the seconds hand.

Any advices how to go about servicing this watch?

P.S. I paid around $20 for this watch

There is some information on this page for 919-1, which has three datasheet pages linked:

https://www.vintagecertinas.ch/en/movements-en/

It says the base movement is 853 / 854, but so far I've not been able to find any details for those.

 

Thank you so much.

Love the yellow date wheel on the blue dial! Color is always a good thing.

Yes it looks really nice, I hope it's the original color and the date wheel isn't tarnished or something.

‘super’ shockproof!  Nice…

😄 double shock, its actually double secruity DS , Certina made a big thing about it in the 60's. 

Hope its ok, ive bin tryin to pick one of these up in decent nick for under £100 for a while.

How exactly does this double shock work? I've never seen it before.

Is it a good watch, based on the images I've seen on the internet the movement looks very nice but is it accurate and high quality?

This explains the double security function of the certina DS system

they are a reputable Swiss brand now owned by Swatch. I’m sure I have read somewhere that they were mainly marketed to the Middle Eastern and Asian markets.

Wow! thank you very much, very interesting.

I still can't imagine how the movement moves in all directions, does it move with the dial? if not wouldn't this affect the hands and the hour wheel? 

I guess I'm gonna have to wait for the watch to arrive to see form my self.

The movement, dial and hands move as one unit within the suspension. There will be a restriction in the build as to how close the hands and dial side get to the crystal.

A little update, the movement is in a great condition but the date change wheel is missing so I'm on the look out for one.

Is it Part No. 2556 that you're looking for?

Yes, Thant's exactly what I'm looking for.

I didn't inspect the movement thoroughly (seems to be running fine) but this is what jumped at me right away.WhatsAppImage2024-08-12at11_33_56.thumb.jpeg.03b3e0071cd206d3187d4e096e571fb0.jpeg

Thank you very much, I did see those yesterday but they are very expensive compared to what I've paid for the watch.

The extortionate customs taxes here makes even more difficult for me to buy this part

I presume that part if the only piece that's missing?

As far as I know yes.

I'll wait and see the local sellers I usually find the parts I need i a couple of months.

Yes, these sometimes break. That's why it's a popular part, hence the inflated prices.  I've seen posts where people make a new spring (the bit that breaks). If you find one, take note how you place it, otherwise the date change won't work properly.

Making a new part is way above my skill and tolls level, I'd like to get there one day though.

What do you mean about placing the part? does it have a specific way to install? do you mean that I have to hook the leaver under it in the hole of tha is on the wheel plate?

Just the orientation of the part. If you have it and place it, you'll see how it works. At one point, part of the wheel is turned so a spring is pushed out. That in turn pushes the date ring. You'll have to place the wheel so the timing for that works. There might be some timing marks on the wheel driving it. There should be some Certina tech sheets out there explaining it better then I do. They used the same system on a lot of there movements, like the 25-651.

Ok,

Thank you very much, I didn't know that I'll be careful when I get the part.

Checked cousins UK and is listing as discontinued, and they are pretty good about crossing over to bestfit if there is another caliber or another  manufacture's caliber part that would work...but might be worth a look anyway...

    • I believe @nickelsilver has a setup like that.
    • I posted pictures earlier in this thread. My lathe and mill are two separate instruments. I think I have seen examples of putting a milling head on a lathe bed...but not certain.
    • Timex Camper, September 1994, new to me. Strap is an old perlon with "Germany" in script etched into the resin on the tail end. Not Horlon or Eulit I believe. History unknown, running strong, losing less than a minute a day. Goals for this: Wear it a ton! Buy crystal lift, clean out the gunk around the ring and under the crystal Eventually swap into a stainless steel case. I've seen a member who has swapped a Timex mechanical movement into the Timex J.Crew quartz field watch case.
    • One of the problems we would have with a watchmaker's lathe is they were made over considerable span of time and manufacturing in the early days probably wasn't as good as it was today. Then if you look at the older catalogs typically it was just the head a few collets and something to rest graver on. So basically a basic lathe with over time things acquired but acquired things may or may not fit. Order today you purchase a used lathe that all kinds of nifty bits and pieces from a seller that acquired from? This would come back to that the basic watchmaker's lathe was used for basic watchmaking like turning things with a hand graver. Then limited indexing is fine because you can make things like stems Which don't need a whole bunch indexing   In the link above the word vector is mentioned and at the link below you can purchase one. Then of course you're going to need the motor that's a little bit extra for the price. https://www.hswalsh.com/product/lathe-vector-watchmakers-48-collets-hl11. That you're going to need some bonus parts like these found this picture online show the classic way of classic gear cutting.   The lathe could have a much bigger indexing disk but it has to be mounted close to the edge. Otherwise you're going to have a whole bunch of smaller disks like this which I think has notches rather than holes. Then as wonderful as these pictures look actually cutting a gear with this is not entirely fun. Look at all is belts all pulling on things and this is a watchmaker's lathe lightweight with lots of bits and pieces attached. It would make more sense if you actually cut a gear with something like this and it tends to be it's not really the best way to do it looks nice on paper but it is not the best way to go. Reality for cutting watch parts would be a bigger machine is much better. Than getting rid of all those belts and pulleys also good. Here is an interesting channel I would've liked of found a different video but this was nice and short if you look at his video as he uses a stepping motor and worm gear assembly for the indexing plate. In this particular video it gets attached to the lathe at about one minute and seven seconds and it looks like it's hiding looks like he has a Sherline. I do know he's had other stuff you'll just have to go through his videos to find it. Then at about one minute and 22 seconds you find out if you set up things appropriately. It's always bad we end up with half a tooth at the very end. Then you will note big lathe yes he's getting a big gear but you could easily cut a watch gear with the setup. And it definitely way more stable than a watchmaker's lathe.         Oh here's a company they been in business since 1911 http://www.fwderbyshireinc.com/
