My introduction and request for movement service manuals


Fabz

Recommended Posts

Hi everyone,

I would like to introduce myself; my name is Fabz and I have recently started watchmaking as a hobby.

I am excited to join this group and learn this art from the more experienced members.

I would like to service 2 women manual watches I have just bought;  the first one is a Bulova (movement 5 BA) and the second one is a Nobellux (movement ETA 980), but I am struggling to find the service manuals. I wonder if anyone from this group can point me to the right documents.

Thanks in advance.

Fabz

Thanks for the introduction and welcome to WRT @Fabz ! 

I'm stalled partially through my first watch movement restore due to waiting on oils and tools (all of which should be on their way).

At this point I still don't have a network of resources to draw on and that's one of the great thing about places like this: it's filled with information.

I have several Bulova quartz watches and suppose I should start looking for a mechanical one.

Thanks for the reply and sorry for my late reply.

Unfortunately the ETA 980 in Cousins is a quartz movement, while mine is mechanic https://17jewels.info/movements/e/eta/eta-980/ . It looks like ETA named 2 movements (one mechanic and one quartz) with the same name?

(movement ETA 980), but I am struggling to find the service manuals..

According to Rannft the ETA 980 is a a 1940 approx. mov.t, back then there was no such thing as the service manual we have today that show exploded diagrams, what lubricants to use, etc. That is because watch repairers were supposed to know their trade well, and that kind of info was trivial for them.

So, all you can find is an illustrated parts list, for example on Cousins UK for the ETA 1010, which is very similar to all other of same age and type.

I see that JDM beat me to most of my answer. the unfortunate reality is every single watch does not have a detailed service manual. If you can find anything at all usually you'll find just the parts list. That's because the watch companies perceived that whoever was working on a watch new how to work on a watch they did not need a detailed service sheet. The day when we start getting specialty lubricants we are seeing more and more individual service sheets but they just didn't always exist. Then even today sometimes I have consolidated sheets with a take a grouping of watches and only have the things unique will be  covered. Then they maybe have separate instructions for lubrication or cleaning  or whatever and will probably never see those anyway because the watch companies today don't like to share.

then the 980 is an interesting movement in that it is a mechanical. The quartz are usually a 980 with a decimal point and some other additional numbers to differentiate them sometimes.

    • I used to just remove the stem pop the movement in its case then put the stem back in check everything then back on the timer. 
    • That's the right technique Mal 👍 If you are ok with a loupe ( which I'm not ) then pick up the dial in your left hand and make a tripod holder out of 3 fingers and then exactly how Mal and me described with your right hand, press and flick out the stem at the same time. You need three fingers to do this, i use my ring ring finger , sounds like mal uses his little finger, just whatever you feel comfortable with. The key point and dangerous side to this is the tweezers or driver slipping off the release screw. Stablise your left arm by resting your elbow on your bench, so that you can hold the movement horizontally flat, use a x5 loupe to view  and good light so you can see well and have a good tight fitting screwdriver to push the release down. Or as suggested a pusher mounted solid upside-down somewhere then all you need to do is push your movement up to it. I'll rig something up in a bit to show you what i mean. Something like this, but tbh its better to just learn to do with your fingers.
    • Thanks Michael, shes a real soldier, it would take a tank to knock her off her feet.  Shes surprised even me and i knew she was a tough cookie.  Good for you Michael, you keep at it. I've been reading your posts re. your watchroom they're inspiring and it doesn't matter how long it takes you to get there its about the journey. Rome wasn't built in a day, our watchcaves are our solitudes, our own little empires where we can shut ourselves away from the crap that goes on around us in the world. I look forward to seeing you progress, I have my own ideas how i like to do things. But in answer to your questions on that thread, just let your workspace evolve around you and how you work. You wont figure it out straight away but you will know when to change it and when to leave it alone. But most of all just enjoy it.
    • That can be tricky. Sometimes I hold the movement from the edges in left hand and with right hand I push the release with tweezers and simultaneously pull the stem out with right hand pinky or something. 
    • I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.
