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?

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.
